I show you how to repair your climbing shoes on your own. This technique is so easy that everyone can use it. All you need for that is a strong shoe glue, I recommend 'Kövulfix', something to spread the glue over the surfaces (e.g. a woodstick) and a clamp. I hope it helps you to repair your climbing shoes on your own.
