What material are most modern shoe soles made of and where can I buy it?
I am going to try to make my own shoes (and yes,if it works there will be an instructable) and I would also like to design custom soles. If you can get the material in pellets instead of sheets please tell me. One more thing, don't just say "rubber" 'cause that's not witty that's just dumb. There are LOTS of types of rubber.
