Motion X Boots are constructed using Duratac™ compound on the outsole and burn guard, offering grip you can count on, without sacrificing durability. Exclusive to Fox, this rubber compound provides the perfect balance of grip and durability, while traction is enhanced even further thanks to the addition of the off-road-ready open tread pattern on the outsole. The slim and flat medial (the inner side) design on each boot increases the surface area to keep you in close contact with the bike, further enhancing your grip and connection. In terms of protection, Motion X Boots incorporate TPU, a hard plastic material, in strategic locations to offer reliable coverage where you need it most, plus have a waterproof membrane to help keep water out on those muddy and wet trail rides. These boots offer the second highest level of protection, with TPU at the ankle, calf guard, shin plate, and toe cap. The patented hinge lockout system around the ankle also stops motion before hyperextension to help prevent injury.
