Hi,
Yeah epoxy will work, also your very strong super glues!
So I gained 20kg during UNI, stress eating. So in my break I walked during day light, got up walked, I went to the bathroom, and ate if I was hungry and drank when I was thirsty, When I was tired I slept.
over that month I went through 8 pairs of shoes, and believe it or not there are Shoes that cost more per wear than others, A good pair of boots will run you about 4 cents per wear. A bad pair of shoes 34 cents.
I used hardwood glue but this just melted during my walking, I tried hot glue gunning and that was not effective, I tried taping them, the tape wore off.
the soles wear off.
Also with leather shoes if you do not wear them for a long time they will get wrecked,
But with shoes if you wear the same pair over and over every day, your going to wear them faster than if you wear them on of. because the shoes do not breath.
Unfortunately with those shoes they are rubber on the sole, which is not really able to replace to soles. so your going to have to use glue,
but you want to also clamp the sole down and spread the glue so it does not harden into an uncomfortable mess,
I recommend removing the whole sole then reattaching it, your going to have to be extremely careful about this.
