Separation Anxiety - "Gorilla" or hot glue [gun]?

[ChipsHH]

I learned of this happening after my move in April/May. Sometime since last September, I wore these YRU Qozmo platform sneakers to a convention for almost a whole day, and that was literally the last time I had put them on.

Fast forward to my move and this was the discovery: the shoe separating from the platform! I couldn't believe what I was seeing! Still can't, even now. I had only worn them once and from that one wearing, they cracked! I'd like to assume that maybe, also, the environment the shoes are in - my room - make them a bit more prone to easy wearing out; rather, drying out because my room is in the basement with very little moisture depending on the time of day and season. But nonetheless, the shoes I paid a small fortune on were now unwearable Unless I put matters into my own hands.

Alas, the best access to anything I can do is either a hot glue gun my step-dad owns, or the "Gorilla Glue" I bought for this case. But BEFORE I do anything/make a possible mistake, do I have the best tools at hand here? Or will I need something more lasting and powerful?

It looks to me like the black fabric coating (vinyl?) is tearing and exposing the white interior, rather than the entire fabric separating from the heel. I don't see any adhesive doing much on a long-term basis. When vinyl decays, it's time to buy new shoes. Sorry. I may be wrong (and I hope you can repair them) but I don't see how. 

Good luck.

I agree with Steve, the vinyl is tearing. I don't think the hot glue will work well, whereas the gorilla glue might be more flex-able.

And if doesn't work, there is always Duct Tape.

Glue from a hot glue gun is pretty tenacious stuff, but can be a bit messy to apply in a 'crack' situation.   But worth a try!

You could even try a thicker superglue, carefully squirted into the gap.

You will need ready to hand some clamps or another means of squeezing the glued shoe together while the adhesive goes off.

If you decide to try Gorilla glue, you'll have to watch it while it dries as it expands.

Have you thought of the possibility of a contact cement,  Barge's is a common tool in the shoe repair shops.
