I have for sale a new pair of size 11 Cabelas waders I've had for 5 years and have never put them on! I used to get them a little large and use them with a pair of felt "booties". They're 5MM neoprene with Armor-Flex. They're not in the catalogue now, but these are almost identical:
I gave over $200 for them; I'll take $130. I live west of Brookville and come to Salina fairly often, so I could bring them to town!
