It’s a top hard-flexing Hawx Ultra boot – a range with the legendary Hawx feel in a narrow 98mm last. It comes with Memory Fit for a perfect personal fit in minutes, and a Memory Fit 3D Platinum liner with pre-shaped heel and ankle areas for an even better first fit. 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 Atomic's Energy Backbone – a reinforced, asymmetric backbone that provides extra strength and edge grip for strong skiing.
