I bought Cabela's 5mm guide weight waders about a month ago, along with their Master Guide wading boot (felt sole). Cabela's claims these boots are sized to accomodate neoprene stocking foot waders. I usually wear a size 10 1/2 shoe, so I ordered size 11 (they only come in whole sizes). They were too small. I sent them back and got size 12 and they seem fine. The boots seem to be made of stout materials, but I have not used them yet as it is still too warm for the waders. If you buy from Cabela's, I would order one size more than you wear normally. Round up on whole sizes not down. Cabela's customer service was excellent as usual on the return. Hope this helps.
