The Bont Riot + MTB shoes are designed to adapt perfectly to the foot of the rider. They have the fully customizable setting with template and thermoformable chassis thanks to the Thermoset resin. The cover is made with microfibres to withstand the rigors of day to day. The chassis is made with Carbon to reduce the weight. It has the retention system consisting of a Velcro closure in the shape of "Z" and the BOA dial with micro-adjustment to ensure a comfortable and accurate support. It also incorporates ventilation holes that help maintain a constant flow of air avoiding excessive sweating of the foot. What fits is the material of the cover not the carbon of the sole.
