When we're chasing lines beyond the ropes, we need gear that blends lightweight efficiency with rock-solid power—and that's where the Atomic Hawx Ultra XTD 115 BOA AT Boot comes in. With the stiffest flex in the women's Ultra XTD lineup, this boot delivers elite-level performance on the descent while staying nimble and comfortable on the skintrack. The BOA Fit System wraps our foot with micro-adjustable precision, enhancing foothold without creating hot spots—a major plus for big days in the backcountry. Its Prolite shell construction starts slim and reinforces only where necessary, keeping weight low without sacrificing power. The Mimic Platinum liner molds to our feet and ankles, while the Memory Fit shell and cuff fine-tune the fit for long-term comfort and response. Add in a 54° range of motion, Free/Lock 4. 5 ski/walk mechanism, and tech-binding-compatible GripWalk soles, and we've got a boot that climbs with ease and descends like we never left the resort.
