Split down the middle, the Endurace U features the skate cuff and ankle support from the old Hyper S skate boot and the forefoot flex from the Hyper Endurace classic boot. The result is a boot that sacrifices very little skating stability, yet still allows for pain-free classic skiing as the forefoot of the boot can flex with your foot. Add the RevoWrap lacing system that hugs your foot and provides even pressure distribution and a softshell lace cover, and you’ve got a boot that performs equally well for skating as for classic - your only challenge is deciding which technique to pick today!
