While there are some indoor cycling machines that can be used without spin shoes, those who are serious about the activity typically own a dedicated pair of indoor cycling shoes or rent them as needed. Both options can be quite costly, but Tiem is a brand that's offering performance cycling shoes that offer the same kind of comfort as a classic running shoe. Best of all, these shoes are fully compatible with all bikes in every studio.
Beyond spinning, the sneakers can be used for lifting weights, TRX or a variety of athletic pursuits. Two of the only activities that Tiem advises against are running and driving, likely because of the design of the sole that makes it suitable for use with stationary indoor bikes.
