Atomic Hawx Ultra 100 is the most flexible and forgiving of our lightweight Hawx Ultra range, offering the legendary Hawx feel and comfort in a narrow fit. It includes Memory Fit for a perfect personal fit in minutes, plus a quality Memory Fit 3D Silver liner with pre-shaped heel and ankle areas for an even better first fit. But the boot has another trick up its sleeve too - Hawx Ultra is the lightest alpine ski boot range we've ever made! The reason it's so light yet powerful: a radical Progressive Shell that adds reinforcement in key zones but reduces wall thickness overall to cut weight, combined with our Energy Backbone - a reinforced, asymmetric backbone that provides extra strength and edge grip for powerful skiing. These boots also feature Power Shift, Cuff Alignment and our Cantable Grip Pads for complete customization.
