I would add that “Through The Roof” sealant appears to be basically the same stuff as “Shoe Goop” (and also E6000), and “Shoe Goop” is IMO pretty marginal in difficult usages. (That includes my “standard test” of repairing shoes or boots with soles coming loose!
Note: Except for quite pricey products, once the shoe and boot industry moved overseas for the most part, I’m not sure whether it is the adhesives or the substrates or both, but shoes and boots just don’t hold up well anymore. I have a pair of light work boots bought from Wally World under their brand of “Brahma” about 30 years ago, and they are still “together”, although I did get them re-heeled many years ago, because the heels had worn so badly! They are just a bit too tight on me now, and the heels and soles are worn smooth, so, traction in them is poor. :-(
Anyway, the point is, even modest price products should be able to not fall apart...
It’s called Shoe Goo . . .
