I want to like these covers but the missing heel cutout is a deal breaker. I've only used it once and already the bottom part is showing wear and tear. At this rate it won't last more than a month.
Also, it fit awkwardly around my left cleat, making it hard for me to snap into my pedal.
I'm returning it and buying something else.
