Compared to a lot of other outdoor sports, rock climbing has a relatively low barrier to entry. You can go to your local gym, rent a pair of shoes, rent a harness and in no time you'll be up on the wall!
If you want your own kit, here's what you should know about the basics and rock climbing gear. So, if you want to invest in your own kit, shoes are a great place to start most importantly!
Because, the shoes that you'll be renting from your local gym will be really worn out, the rubber won't be as sticky as something that you can buy new from this store.
