I've got a pair of these now, waterproof too. very comfy. I think I paid around $120 a few years ago. I used to work on ships and 12-18 hour work days on steel decks were murder on my feet. Redwings helped a lot!
When you buy these at a Redwing store they have a machine that measures your feet. You get exact width, my duck feet are "EE". Made in USA too.
