Flex Rating: 7 (1 Soft – 10 Stiff)Super light and resilient, S4 Shell panels help evenly distribute strap pressure to maximize rebound and resist breakdown for a flex that remains consistent, season after season. The medium flex thin profile 3D molded tongue controls allows you to adjust the profile of the tongue’s thickness to control its flex, enhances its ability to wrap the forefoot, and reduce shell/liner stack-up for improved comfort. Offered in soft, medium, and firm flexing options based on the ride of each boot.

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 Vibram® ExoSep™ Recycled Rubber Outsole is recycled rubber and backed by nearly 70 years of mountaineering knowledge for superior traction, feel, and light weight. Rubber Ice Spikes are soft and grippy with stiffer spikes that dig into ice when slipping isn’t an option. B3 Gel provides ultimate dampening that is formulated to withstand repeated impacts without breaking down.

Speed Zone lacing offers lightning fast lacing control. Customize the fit of the upper or lower zone in seconds – without forcing your friends to wait. Get more power, improved response, and increased wrap – with less effort. Add that with the Imprint™ 3 Liner and Rad Pad you’ve got a quick and comfortable fit.

The Level 2 Molded EVA Footbed with ESS Support Shank and Aegis™ Antimicrobial Coating keeps your feet warm and prevents boot odor.
