I usually buy new shoes every two years or so (mostly Nikes). When walking I seem to not lift my feet high enough and because of this I get a hole the size of a cent at the rear of the sole (under my foot pad).
I'm wondering if there is an easy solution to keep my feet dry when it rains. Either seal up the hole from the bottom or from the inside of the shoe. I don't want to throw them away already, because they still look pretty good.
The only thing I tried is sticking glue inside the hole. This wasn't a good idea, because the glue gets hard and doesn't stick well to the inside of the sole.
