I've worn these quite a bit since buying them at a used clothing store, but the insoles and soles are clean, and I think they can still be worn! I've washed them in a shoe washing machine once before using them. There are no tears, and since I mainly used them as sneakers, the rubber on the slip-on part is still in good condition. They are size 24.5, but the heel is rubber, so they can fit sizes around that. If you have any other questions, please comment before purchasing.
