The SLX boot comes equipped with a Vibram 3D Gumlite outsole, which offers a super grip 3D gumlite rubber, which is 40% lighter than the traditional rubber outsole components. This boot also comes with a dual-component power spine backstay, which allows the rider to fine tune medail/lateral support, edge-to-edge response, as well as the durability. The SLX also comes with an easy slide articulating cuff, which allows the upper and lower zones of the boot to flex independently, creating a fluid forward motion while maximizing heel hold and support.
