Split down the middle, the Endurace U features the skate cuff and ankle support from the Endurace Skate boot and the forefoot flex from the Endurace classic boot. The result is a boot that sacrifices very little skating stability, yet still allows for great 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 have got a boot that performs equally well for skating as for classic - your only challenge is deciding which technique to pick today!
