This may seem like an odd question but I have a pair of Saucony Endorphin Speed 2 shoes and at some point a stone or something similar has pierced the foam base of the sole on one of them. Now every time I use them the shoe makes a squeaking sound as the air is pushed in and out of the tiny hole with each footstep.
Is there any way that people know of to fix this? Is it a case of just filling it in with glue or something similar?
Any google searches I do come up with something called ShoeGoo but that seems to be for more heavy duty repairs and a bit overkill for what I want to do.
