Now that the sole remover has been activated, you can press on the mudguard (on the side of the shoe) and the midsole. When you put the boonfolder in between the mudguard and the midsole, the upper wil detach. You need to remove the entire upper from the midsole.
With a Dremel sanding disc you can remove the remaining glue from the midsole. As soon as the midsole is entirely clean, you can use this for creating your own custom sneaker.
