If you have narrow feet and are looking for a lightweight, all mountain ski boot, the Atomic Hawx Ultra 120 could be the boot for you. This is the lightest ski boot that Atomic has ever made. The Progressive Shell adds reinforcement in key areas, while reducing wall thickness overall to cut weight by 25%. This results in the best combination of snow feel and power ever felt in an all-mountain boot. The Hawx Ultra also features an asymmetrical Energy Backbone that provides extra strength and edge grip for super strong skiing.
