I’m on my second pair. LL Bean replaced the first pair after the glue on the soles melted. I’ve had the same problem with the second pair. I re-glued the soles and heels myself after they began to loosen. Then yesterday I came home from wading my local creek for smallies and found the heels were back somewhere in the Elkhorn. I guess I’ll send these back to LL Bean, too, unless someone knows where I can get replacement bottoms for the Aqua Treads. I’m willing to try re-glueing them (again.) But I’m thinking about going back to Gary Borger felt soles for my next pair of wading boots. The bottoms wear out eventually, and I know about the problems with dydamo and whirling disease. But at least I don’t have to deal with Shoe Goo, Barge Cement and various other things I’ve used to try to hold the Aqua Treads together.
