Giordana designed the SottoZero Shoecover for the serious winter road cyclist. Below-zero temperatures can sap your strength as you body struggles to stay warm. Unfortunately, your hands and feet are the most susceptible. The SottoZero's neoprene construction insulates and fights off the wind to give your foot full protection.
I Like the style and fit over shoe is great as well as keep your feet warm. The only thing is that they really dig into your ankle. They gave me blisters on the back of my heel. my recommendation would be to go with a neoprene cover with out a zipper. My husband sware's by the Castelli Diluvio!
