Atomic Hawx Ultra 110 W is the stiffest women s ski boot in our new lightweight Hawx Ultra range, bringing the legendary Hawx feel to female skiers with narrower feet. It includes Memory Fit for the personalization of a custom ski boot in minutes, plus a Memory Fit 3D Gold liner with pre-shaped heel and ankle areas for an even better first fit. It also has 3M(TM) Thinsulate(TM) Insulation for extra comfort. But most importantly, it s the lightest alpine ski boot we ve ever made! The reason: a Grilamid cuff combined with our radical new Progressive Shell that adds reinforcement in key zones but reduces wall thickness overall to cut weight by 25%. For the best combination of snow-feel and power ever felt in an all-mountain boot, Hawx Ultra also features an asymmetric Energy Backbone that provides extra strength and edge grip for super strong skiing. Add Power Shift, Cuff Alignment and our new Cantable Grip Pads and you ve got one of the best performing, most customizable boots to date.
