Adam Ryan Warrixwrote a review of Castelli Pioggia 3 Shoe Covers on December 7, 2013
The fabric is pretty flimsy. I tore is slightly just putting it on. Also, size up one size. I ordered a large, and they are impossible to get on. They don't have a heal cut out, but that really isn't a selling point for me. If you are short on money and need something to get you through the 35+ degree F days, this would be a good option.
