Ninja Junior - green/yellow, kid's climbing shoes

For the best performance, climbing shoes should fit tight but not painfully so. A proper fit will help you climb harder and longer.

Experienced climbers strongly disagree on how tight is "tight" and what "comfortable" actually means. Combine this with the fact that all feet are different and that each brand has slightly different sizing standards, and you will understand why it is very hard to give proper advice on climbing shoe sizes. Even sizing recommendations based on your street shoe size will always be hit or miss... but mostly miss.

Having said that, if you're a beginner, expect your climbing shoes to feel much tighter than your street shoes. Do yourself a favor and start with shoes from our comfort range! Your second or even third pair will be smaller, and that's totally ok.

We realise this might not be the shoe size advice you were expecting, but the best we can do is being honest 🙃
