I have a pair of Bass Pro Redheads that I like fine. Very comfortable. They've only been in water a couple of times, but didn't leak. I ordered them 1/2 size large and am glad I did.
Used to have a pair of Rockys that I ordered at my regular size. When they arrived, they were a bit snug, but I thought what the heck, they'll stretch some. NOT! That material doesn't stretch a fraction of a millimeter. The farther I'd walk in them, the tighter they felt. Ended up giving them to a friend of mine.
