Velcro_Wide:Extra-wide Velcro for added support and individual, excellent fit.
Rubberized heel cap:External rubber heel cap for added protection.
SupTraction_Rubber Soul CL w/ reinforced shank:We rely on the design and rubber blend of the sole. But we felt that the stiffness can be amped. That’s why we reinforced the shank inside the sole to get a plus in stiffness and make for a proper sole of a high-end trail oriented bike shoe.
