Don't forget Ebay & craigslist for shoes. Used shoes = gross sometimes but if you use at least half a brain you can pick up a good deal. I bought some Lake winter shoes for $35.00 once, guy had mailordered the wrong size & I presume didn't care what he was paid with no minimum bid or anything. The retailed for $300 & are still going strong in the winter.
I've never actually purchased any "gross" used shoes having half a brain and all
