A:Answer That depends on which side of our SPD compatible pedal you choose. If you choose to use the toe cage side, wear athletic shoes. We recommend as hard of a sole as possible. Never ride in open toed shoes, slippers, flip flops, or barefoot. If you choose to use our clip-in option on the reverse side of pedal, use SPD cleats on the bottom of your SPD compatible cycling shoe. We offer SPD cleats on our site as well. It is the two clip cycling shoes.
