"Socks" We do a lot of live aboards so 10-25 dives in a week is normal. I always dive with socks and take a small roll of duck tape in my save a dive kit. We all have different feet, my toes will get hot spots after a few dives. I'll put some tape on the areas in question and leave it for the duration of the trip. It always makes the diving more comfortable for me and I always end up sharing the tape with others. Yes, I also use a crotch strap.
