The K2 Ender is new this year and packs a lot of higher end K2 tech into a mid flexing playful freestyle oriented boot. It’s not just for freestyle riders but for anyone who likes a mid flexing boot that will last a long time. Are they referencing the book Enders Game? I don’t know.
Flex: Very mid level flex that has room for those who like a little range of movement.
Comfort: Like all higher end K2 boots the Ender is very comfortable and doesn’t have a long break in period.
Heel Hold: the BOA liner helps keep the ankle locked pretty well but then it’s up to you to make sure you lace up the outer shell correctly. It’s still great hold but just not as good as the K2 double or triple BOA boots in K2’s line.
Adjustability: It’s not quick but you can dial out your upper and lower if you know how to tie the right knots like a mountaineers not. If so you can create a complete separation from upper and lower as well as dial out each rung of the upper. It’s not easy but it’s very customizable.
Flex Retention: The Ender has “Endo” construction and that just makes any boot last a really long time. The flex will break down a little in the front but the Urethane support in the back will keep the boot from completely breaking down. So day 100 will be pretty close to Day 1.
Response: This right there in the middle and has a nice balance of freedom and response.
Traction: There is pretty good traction here and most icy parking lots will be doable.
Shock Absorption: K2 has good shock absorption compared to many companies out there and the K2 Ender is no exception.
All in all the K2 Ender is a solid boot that is very comfortable and could work if you don’t need or care about reduced footprint technology.
