The Atmos EXP boot is the culmination of 4 years of walkable boot development. From the ground up, the Atmos EXP offers an all-new walkable Intuition+ liner enclosed by a double stitched hybrid shell, a blend of Para-Skin and flexible mesh, for ideal performance and durability. Featuring 3D molded rigid heel and toe components, designed for perfect fit and response. The Atmos is wrapped up with customized zonal fit SuperStraps, making the boot feel even more customized as it gets tighter or looser.
