Amazing Goop works well. That's aka Shoe Goo. Yes, really. Practice before you use it. Use it sparingly and tape it in place for a few hours after you apply it. It will stretch until it cures thoroughly.

I've had no problem in the past with hot glue, but maybe I used a bunch more than you're using.

Silicone might be the best, but when you eventually have to replace it, some of the silicone always stays behind looking ugly.

Droll story: Shoe Goo was invented as (or after its invention, it turned out to be) a good material for building up worn areas on running shoes. The last pack I got was called E6000 and was in a shoe department, but it was black, so no help with IR.

Ennyway....
So a large store's shoe department had some Amazing Goop. Someone from another department, say, tools, found out it could be used around the house for things. Then plumbing wanted some.

Some bright person at the factory figured out that if they made Plumber's Goop and Shoe Goo and Household Goop... they'd get three orders instead of one for the stuff from the stores that sold them. It seems to have worked.

Any of the varieties of Shoe Goo you find are all the same stuff and work the same, no matter what the name.
