Serfas' Radium Road Shoes blend comfort, function and value. The shoes' three offset straps provide a secure hold of the foot, and the triple-density soles deliver the right amount of stiff pedaling efficiency and support. Additional support comes from the integrated heel counters to keep the back of your feet in place. Plus, when you're going fast and breathing hard, these shoes breathe too, thanks to the ventilation of the Syn-Tech uppers.
In order to mount your pedals' cleats to your shoes, they must have matching bolt patterns. There are 3 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 have any questions about cleat compatibility, please contact us. We're here to help!
