If your shoes wear out in the heel area inside the shoe, I warmly recommend these Swedish delicacies. The inside of the shoe including the heel is made by pig skin; it won't wear out.
Skate shoes in general are a fucking lottery. Griptape does mean damage to any shoe, yet I still can't help to think that shoe companies could make super durable shoes if they wanted, but won't because worn out shoes = new shoes = profit. Maybe I'm just pessimistic.
