I use the same shoes. One pair goes over bare feet when I wear a wetsuit. Another pair one size larger goes over drysuit "socks" which themselves fit over light wool socks.
The Desperado shoes sometimes leave part of the ball of my foot slightly numb. It's almost a "funny bone" kind of feeling. Not enough to be bothersome, and only sometimes. My feet are not cold when that happens. I think there is an area that presses slightly in the wrong way. The fit is not that good for me. Maybe the same thing is happening with you.
