Gavin Elite MTB Cycling Shoes A micro adjustable buckle and two hook and loop closure straps allow you to fine tune the fit for comfort and performance, even while on the fly. The buckle features an easy to use ratcheting system. Just insert the strap, pull up on the ratchet buckle (larger tab) to incrementally adjust and tighten, and take care to not pull past the release tab. When your ride is finished push down on the (smaller) release tab to loosen and free the strap. It's that simple! Shoes ship in a right-sized box in order to eliminate extra packaging materials and save valuable resources. The box is reusable, recyclable, and decomposes quickly. Size chart, and more info Cycling shoes like the Gavin Elite MTB Cycling Shoes are meant to be stiff, have a rigid sole, fit snugly and offer good support. They are designed to work with clipless pedal systems. These systems temporarily connect the shoe to the pedal (much like a ski binding system) for increased efficiency of power-transfer. They use a cleat installed on the bottom of each shoe and a matched fitting on the pedal. Cleats generally come with pedals and/or can be purchased separately for indoor cycling class, trail riding, or wherever the next training session takes you. Check out the size chart.
