Korkers size 13 soles x 5 and swift wading sandals with felt soles. I should have put them here first but they are on ebay and getting 0 bids so they are extra cheap right now! See them at:http://cgi.ebay.com/Korkers-soles-omnitrax-SET-5-size-13-/200488723994?cmd=ViewItem&pt=US_Men_s_Athletic_Footwear&hash=item2eae0f261a
