I like that the come in some small sizes, would be nice to see a couple larger sizes as well.

Flex

The K2 Cosmo boots come with a 4/10 flex. They are pretty soft right out of the box, and held their flex throughout the season for the most part. The lack of upper lacing in the liner makes the boot feel softer. If it had a better inner liner lacking system or an inner power strap, I feel these boots would flex a lot nicer.

Lace Up System

These boots are mostly a traditional lace boot, but they do have a boa system for the ankle harness as well. The laces are easy to tighten, but I wish they came with a slightly different type of lace. They have round laces similar to the type you see on hiking boots and they don’t stay that tight. I had to tighten the boots down a couple times a day as I rode. I’ve since traded the laces out for a softer version that work much better and are also easier on the hands when tightening the boot down.

Sole & Traction

The Cosmo boots come with a nice amount of rubber on the sole. They have really nice traction in icy conditions.

Durability

The durability isn’t bad for the price point of the boot. But I did start to see significant wear on the outer liner after just two months of use. This mostly had to do with the outer shell showing wear and tear at friction points on the boot. Everything else seemed to hold up nicely.

Comfort

These felt great right out of the box, the break in time was about a week. But the flex felt fine right away. So if you are looking for a boot that you can use comfortably right away, this would work for that. Other than that, the rest of the boot was comfortable as well. I did have one hot spot that eventually went away after a week of use.

The K2 Cosmo boots are warm enough for average winter temps, but not too great from really cold winter conditions. They were a bit cold when I rode them in MT in some pretty chilly temps. But they do come with a reflective layer in the footbed to help with warmth as well.

Ankle Harness

The boa ankle harness on the inside helps a bit with heel lock. It also helps hold the inner liner together. I found the system somewhat functional but lacking in some ways as well. This boot is more of a relaxed fit boot that is somewhat free flexing for the most part. The upper part of the boot loosens up throughout the day and it is pretty challenging to get it to stay tightly cinched down with just the outer lace system to work with.

I feel the heel lock would be more effective if the rest of the boot held together better. But it fits well and is comfortable when it is cinched down.

Liner

The intuition liners feel great. They have a little bit of a molded liner to help lock in the ankle. There’s velcro at the top of the liner cuffs to help hold the tongue in place. But other than that, there’s nothing else to cinch up the liner itself except for the boa ankle harness.

Overall

The K2 Cosmo boots fit into the freestyle realm of riding. They could be good for someone that likes a soft flex, traditional lace boot at an affordable price. They aren’t too waterproof, so they are a better fit for more mild winter weather. But are very comfortable right out of the box, and have a good amount of traction from the rubber sole. They could be a good fit for an intermediate to advanced rider looking for this style of boot and lacing system.
