The stiff Atomic Hawx Ultra XTD 115 BOA W is built for your freeride ambitions if you're looking for a compact, powerful touring ski boot with a narrow 98mm fit for off-piste terrain.

Thanks to the BOA® Fit System, the shell wraps evenly around the foot, delivering exceptional comfort and heel hold. The Prolite technology combines a lightweight construction with reinforcements at critical areas of the shell and cuff for added stability. With Memory Fit, the shell and cuff can be individually customized. The thermoformable Mimic Platinum liner can also be shaped to your foot – smart: its Power Ankle Lock technology features a firm material layer at the ankle for strong heel retention and direct power transmission.

The adjustable tongue construction allows the tongue to adapt to different foot shapes and instep heights. The 54° range of motion in the cuff enables natural mobility for relaxed climbing and standing – and when skiing down, the Free/Lock 4.5 hike/ski mechanism securely locks the cuff to the shell of the Atomic Hawx Ultra XTD 115 BOA W.
