I am 6'4" 250 WITH SIZE 15 FEET!!! (I think I win
As a newbie I did not want to plunk down so much Cash on some cutom Simms waders so I found Very large sized Stockingfoot waders at Hook and Hackle they are a sponsor of this site and give 20 percent off everything (I ordered a 4XL which sounds ridiculous but with my foot size they were the right ones) they arrived in two days and are just what the doctor ordered. Wading boots are a little easier to find. I got Cabelas Ultralights for like 50 Bucks.
Good Luck,
Rawfish
