Burton Ion 2023 - 2010 Review by The Good Ride
Burton Ion 2021-2023 Snowboard Boot Video and Written Review
Here sits the Burton Ion Snowboard Boot Review from an average rider that’s ridden a ton of boots and has an exceptionally objective perspective.
Update 2023: The Burton Ion has not changed much or at all since this review.
Turn Ons/Swipe Right: Turns incredibly well. Great for medium/wide feet.
Turn Offs/Swipe Left: Super expensive. Not ideal for narrow feet and heels.
The Burton Ion is super expensive and not great for narrower feet. However if you have medium/wide feet it really enhances how you will turn a board. It has a really special turning experience that isn’t common in most snowboard boots. That is what keeps drawing me back to this boot over my long and average snowboarding career.

A Breakdown of How It Rides And Who It Is For
How This Burton Ion Review Happened: We liked this boot sso much we asked to keep it (we only do this with our favorites).
Days: More than I can count over the years and more coming.
Size Tried: 9
Riders: James (Size 9, 5’10” 185-195lbs)
Insoles: Footprint Insole Technology Gamechangers, Sandsole Custom Insoles
Bindings: Union Atlas, Union Strata, Union Falcor, Union Force, Burton Genesis X, Burton Cartel Burton Malavita, and many more to come.
Boards: Many over the years.
James’ Foot Specs
Foot Size: 9 US
Foot Width: E
Arch Length: Right 9.5 and Left 9
Calve Circumference: Top of boot 17” & Bottom of boot 12”
Burton boots fit a wide varitety of foot widths but all of their boots, including the Burton Ion fit medium to wide widths best like my size 9E boot. Length wise it fits true and my almost true size 9’s fit in this boot perfectly.
A lot has changed over the years and Burton used to have the heaviest and arguably most durable boots out there. They would last a long as time and the Ion did a pretty good job at keeping its flex for a while before it softened up. These days it has a little less longevity but it breaks in super fast and the boots seem to be a bit lighter than the older construction. It is still a very well built and well designed boot from the liner to the durable toe that can handle a lot of pressure from a binding toe cap.
Lacing System/ Adjustability/Heel Hold/On & Off
We think the speed lacing is faster on because you don’t have any of that Double BOA micro adjusting that can take a while. You just pull till you feel it snug. If you need to loosen it doesn’t pop open like BOA and loosen too much. Speaking of…don’t crank down your boots or bindings!…you’ll ruin your feet over time but you also won’t be able to turn right.
The Burton Ion does great things when it comes to turning. It has a really unique personality that stands out over other boots when you pair it up with a carving friendly board. The way it initiate and powers out of a turn has a little bit of a cheating feel to it. It just feels like it is helping you into, through and out of the turn in a good way. Not hurrying…but helping you turn better.
Shock Absorption/Board Feel
The sole is pretty reduced to enhance board feel which is great. However, you pay a little price for this. When I put in my FIT Gamechanger Insoles with a ton of shock absorption It does a pretty good job.
Pretty solid traction and I love the almost all continuous rubber sole along the bottom.
One of the best in the industry. The Burton SLX might be a few mm shorter than the Burton Ion but overall it has a consistent footprint size throughout all sizes. It might not be as warm as some bulkier boots but it really helps you size down if you are in between snowboard sizes. Or, just help you carve harder or ride safer in steep terrain due to it having less toe/heel drag.

Burton Ion Past Reviews
The Burton Ion has been around for years and I’ve been riding this boot since the mid-2000s. It’s one of Burton’s signature boots and really integrates well with almost any mostly mountain set up.

2018 Burton Ion Review
James’ Foot Specs
Foot Size: Right 9 and Left 8.75
Foot Width: Right and Left between a D/E
Arch Length: Right 9.5 and Left 9
Calves (Widest Point): 17”
Calves (At top of boot): 12”
2017 Burton Ion Review
James’ Specs Relevant to Boots
Shoe Size: 9 with most boots/active shoes and 10 casual.
Calves (Widest Point): 17”
Calves (At top of boot): 12”
Foot Width at Widest Point: 4”
Mid Foot Width: 4”
Heel Width: 2.5”
Foot Height (Highest Point): 3”
Widest Point Around My Ankles 11.5”
Flex: The flex dropped a bit when on your foot. With the Infinite Ride liner from 2015-2016, it had a stiffer forward flex and felt all around a little stiffer but with the new Life Ride liner, it’s got a softer all around flex. Now it feels medium and just a touch stiffer on the forward flex than the SLX and Almighty. I’d like to see them add some of that closed cell foam or some kind of stiffer material to the liner next year to stiffen it up a little bit.
Comfort: The trade-off with the softer flex is the comfort factor is really high this year from almost day one. Heat molding used to be recommended with the Infinite Ride liner from the past 2 years if you want it comfortable day one but now I’d say don’t do it unless you have a few uncomfortable days on it first. Heat molding isn’t usually as good as the boot slowly conforming to your foot. It fits around a medium sized foot width really well.
Heel Hold: Burton isn’t known for its amazing grip around the ankle but with the change to the lacing system it’s improved a bit. There are also still Velcro J-Bar mounts on the inside of the shell if you want a more snug fit. If you like that Focus BOA or even Triple BOA then this will feel loose. However, it’s a common problem with people to over crank or freak out on how tight the boot goes around the ankle. Most of us at The Good Ride have found that by not over cranking around the ankle and foot it leaves room for your foot to keep circulation but even more important have a little room to flex your foot. That makes for a more responsive because you can use the muscles in your feet much better. That being said if you have a really small ankle you might still be better off with BOA boots.
Adjustability: Speed lace in my humble opinion has some of the best adjustability because the upper and lower are completely separate. I love having a tight upper and moderately loose lower. Only a few BOA boots can do that.
Flex Retention: This isn’t like the SLX or Almighty when it comes to flex retention but it should keep a good amount of flex compared to other boots in its price range. I would like to see more flex retention though. It used to have a little more with the Infinite Ride Liner from past years but with the new liner, it doesn’t last as long. Still, 100 days is no problem without the boot becoming a sock.
Response: The Ion has a nice response that helps get a board to spring from edge to edge very well. It’s a little more response than you would think for its flex and it doesn’t have a twitchy feel. Even with the softer flex this year it doesn’t disappoint and it’s great to pair up with a board that likes a more responsive boot/binding combo.
Traction: Great traction and rubber combined with EVA is a great thing. It’s sad to see that it’s not always the way manufacturers do it nowadays. Great for anything from icy parking lots to long hikes.
Shock Absorption: It’s a tradeoff here between feel underfoot/set up the integration and shock absorption. It isn’t much here and it’s really minimized.
Footprint: in past years Burton was the best but this year Adidas now has a much more reduced footprint. It’s still on the upper tier of being reduced but there is no better out there for reducing toe and heel drag.
On & Off Ease: Very easy on and off. It’s faster than Double BOA getting em on and only a little slower getting them off.
So all in all the 2017 Burton Ion is still one of the best Mostly mountain boots for more responsive setups out there. It’s not super responsive but smooth and springy edge to edge. It’s built around the foot really well.
2015 – 2016 Burton Ion Review
The Burton Ion is an expensive but very well made boot. It’s got a feel and conformity with the common foot that is hard for other boots to obtain. Is it worth the price? That’s a hard question to answer. If you ride a lot it might be but you might get just as much satisfaction with a boot similar to it like the Imperial. It’s a boot I’ve worn off an on over the years and it keeps drawing my feet back into it.
The 2016 Burton Ion has a few changes this year but the general ride is the same.
- The Lacing system is a little bit improved. I’m not sure on the exact tech but it does tighten the boot a little better around the foot than it use to. It also seems a little more sturdy with the plastic barrier on the sides of each pannel.
- The Rad Pads that prevent the tongue from folding aren’t as thick or sturdy this year.
Other than that it’s got a very similar ride and feel to the 2015 and it makes for a great boot for those that prefer more aggressive boards.
2015 Burton Ion Snowboard Boot Review
Approximate Weight: Size 9 Ion 2.6lbs per boot and 5.2lbs for the pair.
There are a couple of new things I’ve noticed with the 2015 Burton Ion.
1. There is a little extra padding between the sole and liner in the form of a thin eva foam pad.
2. There is a little more articulation in the ankle that helps the outer material maintain it’s flex.
3. The toe box is much stronger than past year models (same with the 2014). They keep stiffening it up each year which is really good. It looks like it would be really hard for this to break down. In the past the older Ion’s would start to get a little soft after 40 days or so. Now it doesn’t seem like that will happen. I can’t even get the toe box to bend when I push down as hard as I can.
For those of you who geek out on weight one size 9 weigh’s 2.6 lbs.
Fit: Nice fit that’s true to size. The size 9 boot matches my size 9 feet. The toe box is a tiny bit more narrow than boots like the SLX and other Burton boots but it’s still got some extra room width wise to let your feet expand on a forward lean that’s typical with all Burton boots.
Set Up: 23″ wide 15 front -15 back centered.
Flex: The Ion has a pretty stiff flex but it’s not un-bendable like the Driver X but a little stiffer than the SLX.
Turn Initiation: There is more response going on for the flex than you would think even though it’s flex is on the stiffer side. It feels quick but at the same time smooth compared to many stiff/responsive boots out there like the Driver X.. However if you are use to softer boots you might find them overly responsive and they can over steer the board you were riding with the same lean you had with softer boots. It takes some getting use to. It’s not as responsive as the Driver X but it lives at the bottom end of the fast response spectrum.
Comfort: The Ion’s move to the infinite ride liners increased the longevity of the flex but it doesn’t break in as quickly. It use to feel like day 1 was day 15 but now day 1 can feel like day 1. The denser foam of the Infinite Ride Liner caused discomfort around my Achilles heel and in order to break it in more quickly it would need heat molding from a local shop. After heat molding other infinite ride liners it went away. So the Infinite Ride liners aren’t as comfortable as before but if you take the time to heat mold them you should be good. I’m ok with a little heat molding for a little extra longevity.
Heel Hold: Iv’e never had issues with Burton’s heel hold but some have. If you have a narrow heel/ankle these boots might not be the best for you.
Adjustability: Burton Speed Lace is great when it comes to adjust ability. The upper lace and lower lace is completely separate which is great for those that really like to dial out how the boot wraps around your toe to calf. For me I like it not too tight on the lower and tight on the upper so this lacing system is ideal for me. I’ve never cared about heel lift except for when I was just starting out but these days all day comfort is way more important.
Flex Retention: This model has a little notch as well as different material in the flex point that will help the 2015 model retain it’s flex longer than previous models. That combined with the new infinite ride liner makes the flex life of this boot really good. It will soften up over time but not to the extent that the older boots did. You can get a few seasons out of this if you aren’t rough on them. There isn’t much packing out going on with these boots either.
Shock Absorption: Now you pay a little bit of a price here as it has less shock absorption going on than other Burton boots that don’t have the EST optimized insole. For 2015 they added a little bit of eva foam between the liner and the sole but it’s not going to completely change the ride. With Footprint Game Changer insoles in there it’s better but it’s not like the Burton Fiend or even SLX when it comes to shock absorption. It’s a really unique feel that’s much more connected with the board and it rocks back and forth much more easy than normal soles. There is one thing that’s interesting here and I think that because there is less hard rubber tread than non est optimized soles you can feel the shock absorbing material give a little easier under foot and it feels better for smaller slow speed shock absorption. So it’s a give and take between shock absorption and feel under foot. I usually lean towards more shock absorption but I have to admit the feel underfoot is special and it’s a pretty cool feeling. I just don’t like wearing these boots with bindings that don’t have much shock absorption. If I pair them with Burton Re:Flex bindings though I’m more than fine.
Traction: Very good traction. I’ve never had a problem with any year Ion when it came to traction. It does have less tread than the SLX in thickness and surface area.
Footprint: About a size smaller than the boots of old. Some companies haven’t chose to reduce their boot size and those that didn’t are much longer than the Ion.
On & Off Ease: Speed lace is very easy on and off.
So all in all this is one of the better boots I’ve ever tried for those that want comfort, response and support. It’s pricey but for some (like me) its worth it.
Regarding the Burton Ion Auto Cant: Burton has a unique thing going on with a few of their boots and this is one of them. The Burton Ion has a sole that rolls easy inward to line your ankles, knees and hips up better with your stance width. It’s easier on the body and has less fatigue. It’s also doable with Burton’s Auto Cant bindings as well as Canted bindings from other companines.
Regarding Reduced Footprint: Burton’s foot print is almost a full size smaller on the outside but the same size on the inside. So a size 10 boot is still a size 10 on the inside but more like a size 9 on the outside. This really reduces toe drag and Burton is the best in the industry when it comes to this. The warmth and feel of the ride is unaffected and all you have is a boot less likely to catch the snow on a hard turn or in steep terrain. This is great for those that have big feet, ride narrow waist boards or are in between board and binding sizing.
Riders: James, Peter, Eli and a few others
Bindings: Burton Cartel, Burton Cartel Limited, Burton Diode, Union Force, Flux DMCC, Flux SF45,Burton Genesis, Union SL, Union Contact Pro, Burton Cartel EST, Burton Malavita EST , Burton Diode EST and many more
Boards: Jones Mountain Twin, Gnu Impossible Series, Yes Greats, Rossignol One Magtek, Lib Tech Burtner Box Scratcher, Never Summer Proto, Never Summer Cobra, Lib Tech TRS, Lib Tech Lando Phoenix, Lib Tech Hot Knife, Arbor Coda, Burton Barracuda, Burton Nug Flying V, Gnu Space Case, Gnu Riders Choice, Slash ATV,Yes Jackpot and many more.
Flex: The 2014 Burton Ion has stiffened up it’s flex and the overall feel of the Ion is a little more on the stiffer supportive side than previous years models. The Ion Leather is even stiffer and closer to the Burton Driver X.
Comfort: All years we have come across are very comfortable and the 2012 plus models offer up almost day one comfort. They break in incredibly easy without breaking you in the process. You would expect this at the high price point but not all high end boots deliver like the Ion. The Ion Leather was not as comfortable as the regular Ion but it’s still pretty comfortable and just needs more time to break in.
Heel Hold: The heel hold is good enough for most and none of us here at The Good Ride have had any issues with our heels lifting. It holds without feeling tight and constrictive which is a great thing. If you have problems with a smaller ankle or a heel that often lifts up the Burton Ion should work but the boot doesn’t have the grip of higher end BOA competitors. You can put in J-Bars around the ankles though to secure the boots even more. Sometimes Burton provides them but if not you can buy J-Bars from other providers
Adjustability: What we love about Burton Speed Lace is it allows you to to have complete separation between your upper and lower lacing. This gives Burton the Advantage over BOA here because even most Double BOA boots don’t have complete separation. They usually share the ankle where Burton doesn’t. So BOA win’s on heel hold but Burton is the hands down winner for adjustability. Also Speed lace is easy and almost as easy as BOA.
Flex Retention: The 2013 and Below Burton Ion’s did very well but the 2014 Burton Ion has a few upgrades that make it the better choice. There is a new liner that has a different material that is made to last a lot longer and retain it’s original flex longer. Before the Flex retention was good but now the Ion can last a lot longer than before without going completely noodle on you. It’s still not like the SLX but it’s a lot better than the previous years models. Also the reinforcement around the toe has been beefed up so it will not break down as easy after many days on the hill.
Response: The Ion is smooth but very responsive and fine for even challenging boards. It doesn’t have the sharp response of the Driver X but it’s got a more well rounded response that is fine with a park board or a challenging to turn Freeride board. It’s hard to describe but it just does an amazing job with just about any board you want to ride. The Ion is best more in the middle but it’s still great with Very challenging and Easy Turning boards. The Ion Leather is a little more responsive and closer to the Driver X but still has more of a smooth ride like an Ion.
Traction: Excellent in just about any condiiton.
Shock Absorption: The last few years The Burton Ion has reduced it’s cushioning by a lot and not it’s pretty thin. It still has good shock absorption but they are going more for feel than shock absorption these days. The older models use to have a pillow under your foot that was un-matched. I’d personally like to see something in the middle closer to the Imperial and SLX .
Regardless of wether you buy the 2014 or 2013 Ion they are all great. The 2014 offers up a little more support, a stronger flex and a longer lasting flex than the older Ion so it seems like there is some improvement going on here.
Burton Ion 2013-2010 Review
It’s very similar to the 2012 except it’s lighter and the flex seems a little softer. Both the 2012 and 2013 Boots are a good call.
Flex:What some might like or dislike about the Ion is the flex feels softer on the shelf but when you get it on it’s very supportive. The boot is definitely better for stiff to medium boards but we have had no problems riding this boot with softer boards. It seems to adapt well to the board under foot.
Comfort: The Burton Ion is sooooooo light and sooo comfortable. Each year it keeps getting easier on the feet and staying ahead of the competition in terms of comfort. In 2012 they tweaked the fit a little more to give the Ion Even though the boots have softened up the last few years their aren’t additional pressure points. It’s a boot you can go out at night with too if you want.
Heel Hold: If you are the average rider the heel will be locked in as soon as it’s tightened up correctly. Burton’s boots seem to accomodate the widest variety of users with their boots.
Upper and Lower Adjustability: The dual zone lacing system keeps adjust-ability at its finest. In our opinion Speed Zone Lacing is allot better than BOA if you crank your boots up really tight. It’s very hard to create a pressure point no matter how tight you make them. Its not lightning quick but much easier than lacing. You have four things to adjust and fasten before getting it right. 2 inner and 2 outer. For 2011 and 2012 The Ion has improved the longevity of the Speed Laces. Before the laces would start coming apart at the end of a 100 day season which was frustrating. Now they make it through the whole season without even a sign of wear.
Response: To us response and comfort are the two most important things in a boot. So you know this is comfortable but how is the The Burton Ions are a light mid to almost soft flexing boot that some how creates the response of a super stiff boot. This is hard to describe but the boots seem to help you get ready for the next turn. This is something that we haven’t experienced in any other boot and it’s very unique. We can’t put a finger on what tech makes this boot so adaptive to any condition. It’s probably a combo of forward lean reflex tech and other tech beyond our comprehension. We’ll just give up and say this boot is an industry leader when it comes to response. It’s a great freeride boot but it’s also tweakable for park riding (even jibbing) which again is rather unique.
Traction: The traction is great on just about anything you walk on. The rubber works very well on ice or deep snow.
Sole Cushioning: The sole cushioning is great in the heel with the air cushioning. Its not marketed very much but there is some sort of air spacing between the white part of the inner sole and what ever is inside. What ever it is the result is an incredibly smooth ride. Heel hold is stepping up but it would be great to have perfect fit without having to fu^& around with the J-Bar inserts. When they are in its hard to take out the liners to dry without ruining the J-Bars and your perfect heel hold. That is why its an 8. This boot makes board and bindings feel like they are all one. Especially if you have a burton binding. Burton has allot of competitors now and its hard to stay at the top so give them big ups for this boot. Also bitch at them for making them soo expensive!!!!! For 2012 the large deep padding system has been removed to make the boot lower profile. This is to work better with the est binding system. It’s still good with shock absorption but we liked the older versions better.
All in all the Burton Ion is one of the more diverse all around boots you can buy. We’d like to see this add some better ankle articulation but this boot still blows doors and will integrate well with just about any type of set up you can find.
2012 Burton Ion– For 2012 the stiffness is about the same but the comfort is a little better than the 2011’s. They also added a cant in the sole of the boot. to allow your hips to align better with the board/bindings. It’s not really a cant like you see in many bindings these days. Instead the boot just seems to roll easier to the inside than a regular boot. It doesn’t walk funny or anything. The new low profile set up also removed a majority of the super thick/cush padding most people expect with the older Ion’s. The “auto cant” tech was a nice leap in tech so even though it’s not as shock absorbent in the past it’s still hands down the choice over the past models.
2011 Burton Ion– Burton stiffened things up a bit and but not as much as before 2010. Their boots also have a more solid feel that offers the support we expect from Burotn.
2010 Burton Ion– In 2010 the Ion like all Burton boots was made really soft compared to the 2008 and 2009 models. The Ion wasn’t stiff to begin with so some weren’t happy.

Burton Ion User Reviews
Not what they used to be
Don't get me wrong, these boots are still amazing when it comes to performance. I have been riding Ions for over 20 years, in fact the only boot I have ridden, always in size 10. In January I replaced them with this year's model (speed lace) and after 30+ days a pressure point in the upper part of my right foot never went away. I also found that the shell does not wrap around the liner as uniform as my 2018 ones did. I actually wonder if I just got a poorly manufactured boot or if the sizing has changed slightly??. I have never had an issue with my previous models... Burton has changed a lot in this boot with less structural support, not sure the impact of that... just beware...
The very best on the market
I have these boots since 2017 and they are still brand new. They are a true work horse, still warm and super responsive.
However I can relate to some people that complain about ankle pain. Owning a lot of ski and snowboard socks, I can ensure that the ankle pain comes from certain ski or snowboard socks. You have to be specially picky choosing your socks so that you dont feel the ankle pain or abrasion. Therefore, I think it would be good to have some socks recommendations to work with these boots for all the folks that complain about this issue. The ankle support from these boots is crucial for the control you will have of your board with these boots. It's not a negative point for me but it can be for a lot of people out there.
I bought these because I read somehwere that the heel hold is really good.Well it's not, perhaps it could have been. There must be some kind of design flaw in this boot to be honest. And I don't understand how a company like Burton could have produced this without knowing what happens when you tighten the ankle dial.
I have the boa version 2019 and I never tighten the dial for the ankles. It causes a lot of pain and cuts into my ankle if I tighten it. Waste of money in my opinion. Stay away you have been warned.
Stiff and Painful
Oh the pain in my ankle! I've owned multiple pairs of Burton Motos, and Imperial boots. The Ion is the only one that causes pain on the inside of my ankles. Super stiff and responsive, but for some reason the fit around my ankle just ain't right. After a month of riding, I thought it would break in and become more comfortable. However, after a few hours I need to take off the boot to relieve the pressure. After reading the reviews, this seems to be a pretty common problem for some of us with the Ion. This was a super expensive boot and now I'm looking replacing them cuz it's just too painful to live with.
Burton ION 2016
well I am riding SNB for 11 seasons , for 5 seasons I am spending whole winter on the mountain as SNB/ski instructor so I am riding a lot.
I ´ve had IONs since 2017 ...my experience with it is very good...of course they have some downfalls in longevity like :
1.(hardenplasticTIP of ur boot VS veird material of the boot..the boot is loosing durability in there since the plastic material properties are to expand and goback the other way depend on temperature?the sews are also geting lose)
2. one more downfall of them is back side of the rubber and front tip is not so tick and glued so well.
3.that plastic is keeping cold pretty well so during the whole rly cold freezing day ur feet is gonna be not so happy.
IN term of perfection of this boot IMO in 2016 at least was :
1. infinite ride liner(hard to get in at start..with combo of the boot made it very stiff... i felt like my feet is in concrete day 1, dont forget about new sole + good socks- helps a lot)
2. Lacing system
3. long lasting flex...(responsivness)
Would i reccomend this?for 30+ day rider for sure. mh since I am in the boots all day long..that warmness is missing a little bit...also depends on what u expect individualy...u have to know what are u aiming for ...It´s definitely not boot for beginer...that responsivnes of this boot is not going to tolerate too much mistakes. Especialy in combination with stiff board , stiff binding. IMO it´s about the finding balance between those 3 kindafriends.
een boarding since mid 90's, mostly using Burton gear, been through about 10 different set-ups to day and...
..more importantly, coming from Burton Ambush, I've got to say that Burton IONs are a huge improvement when it comes to stiffness, flex retention and overall feel. Last season I managed to sneak a real bargain - I've got a 2016 model with an infinite liner. It did take me about 15 days to break in, some of which were rather a bit painful than comfy, had to push myself a bit to bear the pain, but then it was worth it. Now, there are almost perfect. I’d be hard thinking about any better boot than those. Moreover, they go well with Burton Cartel/Genesis bindings matching the stiffness range nicely, which I think is quite important when picking up a good combo. Here and there, especially by the end of the day, they still can feel a bit painful but when you pay some attention to tying up the boot you should get what you're aiming for. One thing that definitely stands out is that they are quite waterproof and really help to keep water out the inside area, which Ambush couldn't really do even on colder days. All in all, the IONs are really good bid for those lads loving semi-locked to locked feel. Bombing down the mountain feels great, you can count on them in all situations likely to arise. However, I wouldn't recommend them to newbies and seasonal riders doing up to 10-15 days per season as they are really hard-charging boots. There are definitely better boots out there, like AMB, Ruler…
wear & tear
I have used Burton Ion's for the last 10 years and bought a new pair for this season as I aiming for 90 days riding (67 so far). First impressions were good and generally they have fitted OK, but and they are big but's the inner lining has not managed to remain intact and on the right foot there is a hole by the inside of my ankle, when riding for more than a few hours my big toes seem to get loads of pressure and turn black at the ends. In order to reduce heel lift I need to tighten the laces as much as I can and even then there is just to much and I end up adjusting the boots several times a day to stop the tongue twisting in the boot. These are high end boots and the latest version (2018/19) just don't live up to the quality and fit of my previous Ion's which I used for circa 130 days and only changed them because the did not have enough life in them to do this season
25 years of boarding and Burton Ion Redwings are the most painful boot i have ever used. The ankle pad hits right under my ankle and has gave a massive blister that has turned into a hole after 10 days of riding. Bruised as well. Had to take time out because they became so unusable. In the end i have took a knife to the inside and cut out the liner. And made padding and taped that to my ankles just to ride. Joke as they are most expensive boots i have bought. Never again Burton. Thing is i used Burton board binding and socks.
Most uncomfortable boots I've ever owned
I've been boarding since the 80's and I've had some really uncomfortable boots from Sorels with ski boot liners to others that just had zero stiffness.
The 2016 Ions are constructed well but the infinite ride liners don't work for me. The liner has very aggressive ankle support, unfortunately, they hit right on the bone.
I've tried heat molding and hoping they would break in, I'd have a better chance of my ankles molding to the liner than the other way around.
Maybe other would fare better but these are a no-go for me.
All mountain but for advanced rider
Overall, the 2017 model of these boots feel stiff in the foot with a lot of free space in the base of the foot for people with large or flat feet. They are very warm and they could have some more impact cushion. The responsiveness of these boots is incredible. I didn't have that break in period that everyone describes from previous versions of the boot. This liner is awesome and the boot itself is indeed on of the top of the line from Burton. Similar to what happens with ski boots, you can't buy these boots after owning a a pair of the entry line Burton boots. These boots are really only for advanced riders that are really specific about what they want to achieve with these boots. For the seasonal rider, I wouldn't recommend these boots since there are better choices in the range of the AMB and Almighty.
