Based on the popular 100mm Hawx Prime last, the Hawx Prime XTD 120 CT GW gives backcountry skiers with higher volume feet a chance to join in the fun. Bootfitters using the Atomic Memory Fit HD process and a few tricks have been successful in fitting many wider and taller feet in the Hawx Prime boots, and the XTD version is no exception - EXCEPT that it happens to also tour great. A 54˚ range of motion, the proven Free/Lock 4.0 lever system, and Atomic's Prolite construction mean you can be at the head of the pack going both uphill and downhill.
