Flex Rating: 4 (1 Soft – 10 Stiff) Shrinkage footprint reduction technology reduces the boot’s overall footprint one full size, meaning a men’s size 10 fits like a size 10, but has the footprint of a typical size 9. Shorter, lighter, sleeker – never suffer from toe drag again. The articulating off allows the upper and lower zones of the boot to flex independently and create fluid forward motion while minimizing shell distortion and maximizing heel hold and response. The Flex Spine Backstay lets you get effortless medial and lateral mobility with ample edge to edge support for when it’s time to throw down the landing gear.

270° cushioning offers more cush and less weight. A 50% larger airbag covers approximately 75% of the midsole for unstoppable impact protection. The new Stay Puft Tongue allows you to tuck that knee and tweak it with the smoother forward motion and cushy comfort of it’s padded, progressive flexing upper tongue construction.

The 2:1 Power Lacing System ratio gives you more pulling power with less effort, making it easy to fine tune your fit. Add that with the Imprint™ 3 Liner and Rad Pad you’ve got a quick and comfortable fit.

Bring the storm. The Ultra Cush Park 2 Footbed combines with the Aegis™ Antimicrobial Coating to keep your feet warm and prevent boot odor.
