I bought three pairs of these for my indoor cycling studio. It was shown as a common pedal for indoor cycling classes and I assumed everyone cant be wrong......well....they were kind of wrong.As a SPD or Look pedal I had no complaints from clients.For clients who used their gym shoes I had complaint after complaint. I decided to take the class with the bikes with these pedals and my feet still hurt a week later. I don't think there is enough foot space for the shoe and and the whole class I felt like all my weight was at the very front of my foot.I am returning the three pairs that I bought and replacing them with the stock pedals until I find a spd/toe clip variation that is comfortable.
