The Atomic Men's Hawx 100 Ski Boots featuring i-Flex are a unique 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 100 flex and ASY Pro liner transfer power directly to the ski. Four lightweight Edge 7000 buckles and an extra-wide strap provide superb support. This boot allows you to control the ski more precisely and have reliable traction. Using a combination of heat moldable EVA and memory foams, the ASY Pro liner gives the best combination of comfort and warmth while still providing phenomenal precision and energy transmission. Combined, this creates a boot with a fit that allows you to wear them all day and the confidence to ski the most gnarly terrain. The Hawx 100 also includes a SIDAS Insole to help with general foot comfort, warmth and heel retention. The Hawx 100 is the perfect boot for advanced skiers who like to combine great fit and power transmission with optimum control in all situations.
