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 three configurations (diagram) used on cycling shoes, SPD-R, Look/SPD-SL and SPD. Road shoes feature one, two or even all three of these. 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!
