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 articulating cuff allows the upper and lower zones of the boot to flex independently creating fluid forward motion, minimizing shell distortion, and maximizing heel hold and response. The medium flex thin profile 3D molded tongue controls allow 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. The power spine backstays fine-tune medial/lateral support, edge to edge response, and durability.
