The Atomic Hawx Ultra XTD blurs the line between a supportive freeride mono and an all-around skinning mono. The Hawx Ultra XTD is designed for skiers looking for a versatile, high-performance freeride shoe. The comparatively narrow last and shorter shaft make the Ultra XTD a good choice for those with narrower and smaller feet. The Hawx Ultra XTD has an innovative walking space and frictionless stem movement, just like Atomic's even lighter Backland series boots. The Ultra XTD features high-quality Mimic Platinum inner shoes that can be customized to fit your feet. The innovative Prolite structure strengthens the most important areas in terms of power transmission, but keeps the overall weight light. This is the lightest mono of the Ultra XTD series. This Boa version has a nifty Boa mechanism for precise, reliable and light operation. - Fits both alpine standard and Dynatech type bindings - Flex: 120 - Last: 98 mm - Mimic Platinum inner shoe - Memory Fit - Gripwalk soles - Prolite c
