For the Latch mountain bike shoe, Giro started with a new fit that brings the foot closer to the pedal and flattens the sole profile, optimizing the contact patch between sole and pedal. Then they collaborated with a team of rubber engineers to formulate Tack Rubber, a highly elastic compound that matches grip with durability in the new Gamma tread design. And at the heart of the shoe is a revelation in performance called Mute Foam, a midsole foam that's specially engineered with a slow-rebound action that cuts chatter and vibration to help keep you connected to the pedal, regardless of ruts, roots, and rocks. The unique combination of fit, a fast-drying microfiber upper, the grip of Tack Rubber, and the damping of Mute Foam makes Latch a new benchmark in flat-pedal performance.
