For those looking for more fun than victory the Shimano SPD system offers the efficiency advantage of clipless pedals with shoes that offer walking comfort. Combined with any SPD shoes, the multi-directional release cleats provide a great combination of on-bike performance, spin class compatibility and off-bike walking comfort. Shimano invented the SPD, so you can depend on it! The Shimano SH-56 has been providing legendary in-the-dirt dependability, reliability and sheer endurance that has made the SPD the world's go-to pedal technology.**Note: These cleats should NOT be used for riding styles that may involve pulling up on the pedals or for activities, such as jumping, in which pulling forces are applied to the pedals causing possible release from the pedals.
