Not all I wished for.
First of all, these aren't really shoe covers, at least not until you cut a big hole in the bottom for your cleats. I my feet still got really cold on the first ride and it didn't feel like they stopped the wind at all. As a second sock layer (which Capo says they also are) they weren't much better. I'd spend the extra dollars to get the PI Cyclones if you plan to ride in cold weather.
