Im using the hell out of this stuff, and its helping my shoes wear so much more evenly! Thanks shoe goo!

Also, to contribute more useful feedback, it dries very durably, it probably wears down a little faster than the rubber soles on your shoes would, but its also $3/tube or whatever, so that's not a real complaint. I always put it on when I can give it a couple days to cure and that seems good. It prolly takes a little over 24 hours to get fully set, but I put it on pretty thick. Also, set it up in a good sized room or outside, its not really stinky, but it's noticable.  will definitely buy more when the time comes!
