Brian C.wrote a review of Castelli Ultra Shoe Covers on February 16, 2014
Familiarity: I've used it once or twice and have initial impressions
I bought these to complete my winter castelli kit. my feet were always cold with other shoe covers. Although they fit well 44 was a snug large, the rear zippers are a pain to close and after wearing them twice the whole toe ripped out on the bottom. I honestly may have taken 30 steps in them? Just too thin and flimsy. I returned them!
