Shimano's SH-RT31s are great, lightweight Cycling/Spin shoes. The nylon mesh uppers provide high breathability, while dual Velcro straps enable you to customize the fit for all your rides. Shimano's slim-line walkable outsoles have a durable rubber layer which provides extra walking traction. And, these shoes feature recessed cleat mounts for SPD cleats (sold separately) so you can pedal with plenty of power. These are the shoes to use at all the local spin clubs.
