“There are different climbing shoes for climbing cracks in granite, for sport climbing, for gym climbing. It’s all about what you want to do. For bouldering, you just need climbing shoes and a chalk bag with some chalk. For sport climbing, you also need a harness, rope and belay device.” A lot of climbing gyms do gear demos, where you can try out shoes and see what works best for your feet and climbing style.
