The innovative Atomic Men's Hawx 90 Ski Boots featuring i-Flex is a unique go-anywhere performance boot that promotes natural forefoot flexibility and improves balance. I-Flex makes the skier more sensitive to feedback from the ski, and offers more control with less effort. The 90 flex and ASY Sport liner are stiff enough to transfer power directly to the ski without being overly demanding. Four lightweight Edge 7000 buckles and a wide power strap provide superb support. The Hawx 90 is the perfect boot for intermediate to lighter weight advanced skiers who like to combine great fit and power transmission with optimum control in all situations. 100mm Last.
