Now upgraded with a BOA® Fit System, the Atomic Hawx Prime 115 S Boa Ski Boot roosts at the top of the all-mountain boot game. The 115 flex is well suited to powerful rippers who need control in pow, chunder, and on groomers, the 100mm last balances a high-performance fit with comfort and warmth, and the Mimic liner locks your heel and toes in place so that you can get on edge and off with precision.
