I ordered these with the notion that I was finally going to find a shoe cover that fits my speedplay cleats (fitted way back). I received them as ordered, but to my dismay they were too small! I have Specialized S-Works shoes size 39, and I could get barely get them around the heel. However, that was not the dealbreaker. I have some skinny ankles, and these did not come even close to getting around them. The product is well made, feels great, and looks fantastic. I have no doubt that if it would have fit, it would have suited my needs perfectly. However, it sizes quite small, and for that reason I had to exchange it. I marked it down because Giordana should indicate on their sizing charts that they size quite small. Make sure that you order at least one size larger than you would expect to.
