In order to mount your pedal cleats to your shoes, they must have matching bolt patterns (pedals come with cleats, shoes come without). There are four configurations (diagram) used on cycling shoes: SPD-R, Look/SPD-SL, SPD, and Speedplay. Road shoes can feature a combination of these while mountain bike shoes usually use the SPD pattern. If you're unsure what bolt pattern your equipment uses, please contact us. We're here to help!
