We view the entire mountain as our playground and require reliable performance on the up and on the down, so we glide out strapped into the Atomic Hawx Ultra XTD 120 BOA GW AT Boot. The Free/Lock 4. 5 walk mode mechanism opens up 74 degrees of motion, and the Frictionless Pivot smooths the transition for restriction-free strides on the skintrack. When locked in downhill mode, this boot's stiff flex and Energy Backbone have our skis responding instantly to our demands and keep power driving to our edges as we sweep down long, steep faces.
