I got these for my wife. She has only used them once so far, but it was in a pretty heavy rain and she was very happy with them.
The picture looked good but in reality they are useless. The ankle opening is so tight they wont even go over the shoes and there isn't a zipper so ended up sitting in the box.
I love Giro products (helmets, gloves). But these aero covers... while they look awesome... have no zipper. Almost impossible to get on.
These were tight like velotoze, but the material is much stronger. They may not be as aero, but I don't worry about tearing them when I put them on.
For the price, the Giro Ultralight Aero Shoe Cover is a good shoe cover. With added material to protect the toe. The fit is a little tight and all one peace, I can not get the show cover on with my foot in the show. it is best to get one size bigger then the size chart shows.
Very hard to get on and off especially after a long, hard time trial, but they are very durable. I purchased a similar product from another company (primarily because these were so hard to get on and off) The other Aero Shoe Cover cost more than twice as much but self destructed after only about wearing them five times.
