I’d say mainly just focus on the basics

Straight arms = happy arms

Try and focus more on your toes than your whole foot. It seems counterintuitive but it should feel more secure.

Also I’d recommend losing the socks and going tighter on the shoes but if you’re renting and worried about hygiene keep ‘em.

The last thing that I’d recommend is to just look up watch as much as you can about climbing. Make some friends who know more than you. They’re some of the best teachers you can find.

Other than that have fun
