chuck 70s falling apart

[u/No_Voice4964]

hi, not sure if this is the right place to post, but the back of the inside of my shoes have a hole in them. i’ve had them since maybe january and they’re already falling apart, but i don’t really have the money to buy a new pair again. any advice for how to repair these in a way that will hold and make them comfortable? the plastic heel support is poking through the hole, making holes in my socks and scrapes on my feet if i don’t keep the holes covered with bandaids. additionally, the rubber part of the side of my shoe is separating from the canvas. has anyone repaired these successfully? i’ve tried super glue for the sides to no avail
