A couple of the guys that I hunt with are wearing Muck Boots. Most of them are wearing them due to the fact that they have large calves, and couldnt wear a pair of rubber boots without rubbing the hair off their legs and getting blisters. They all say they are not boots to wear for super cold weather, but are very comfortable.
I cant imagine what it would cost to have boots custom made, but I'm sure that there are some boots that will work for you at alot less cost.
I'll check with a couple of the guys tonight at work if they are working, and see what else has worked for them.
Sometimes its nice to be an "average" sized guy. <img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle>
