I bought a set of these in a size 8 regular, they were a little tight for me around the calves, but i loved them so much i bought another pair in a 10 stout. I am 5'5
about 180 lbs, my shoe size is a size 9, and My calves are about 17 inches round and even in the stout they are a little tight but they don't cut off circulation and i can still layer up for the cold hunts. The stout size is a little baggy on me since im so short, but it allows a ton of room for layering.
I have tried banded and Drake waders and in my opinion these are much more comfortable.
