What do you do with worn out trainers?

[LaFemmeDamnee]

I live in my trainers and walk a fair bit so I wear out the soles. My current trainers have absolutely no tread in them at the ball of my foot. I have bought some new ones but it feels weird to just bin the old ones. Any ideas or are they literally only good to be chucked? They are definitely too worn out to charity shop.

They can be recycled

I put them in the clothes and shoes recycling bins. There’s now one at our primary school but before that there was one at a local park and one at the dump.

Please dont put them in the clothes recycling bin they get sent to poorer countries in huge containers then the containers get bought and picked over again for selling be honest if they are too crap for you wear the person the other end of the chain is not going to sell them and they end up in huge mountains of rotting clothes and shoes , so just throw them away
