I have a pair of neoprene waders I'm not quite ready to give up on (sorry, I'm cheap). While walking out of a spot last year, I stepped over a pile of busted up concrete and planted my wader boot squarely onto a piece of rebar sticking out. The hole went clear through the rubber boot on the inside just above the ankle. I patched them using a kit from Frog Toggs and they worked fine the rest of the season. This last weekend during youth season, they started leakin again. I'm sure it's through the patch job I made last year, as I was only wet from the ankle down. Wondering what's your best recommendations for patching waders?
