The Nitro Profile TLS Step On snowboard boot was developed in collaboration with two brands passionate about snowboarding, combining Nitro's ultimate fit with the groundbreaking convenience of Step On. This boot offers unmatched comfort and convenience, allowing you to get more runs in and stay out longer with a fit that lasts. It provides a secure foothold and comfortable fit from early morning groomers to last-run powder adventures.   The Step On Nitro Rubber Sole ensures the traction needed for exploration and durability for season-long use. Features like the Armored Spine, Internal Ankle Support, Power Tongue Stiffener, and Re/Lace Liner Locker provide the unique fit and support found only in Nitro boots. Additionally, the Cloud 9 Liner and Therminator Shield keep your feet warm on the coldest summit hikes.
