A perfect fit must start with a perfect shoe fit: that's why the original HAWX - best-selling shoes with amazing comfort and optimal balance - were created. And now with the unique boot width of 98mm in the new HAWX Ultra , all-mountain skiers with a narrow foot can also enjoy the legendary HAWX feel. The HAWX Ultra is also special because it's also the lightest alpine ski boot ever - by 25%! This is thanks to the radical new Progressive Shell technology , which adds reinforcement in key zones but reduces wall thickness and overall weight. Plus, the new Memory Fit 3D Liner is added for total comfort. All in all, the HAWX Ultra keeps your feet incredibly light and nimble as you blast your way down the hill - with the best combination of snow and power you've ever felt in an all-mountain boot.
