You don’t need to wear a full rock-climbing shoe unless you're a professional. Wear a regular pair of sturdy, flat-soled shoes that fit well and can be used for gym activities before going into the climbing walls. If you've been invited to try indoor climbing or bouldering for the very first time, then it's best to go in with the La Sportiva Katana climbing shoes. The shoe gives more edging power when climbers need to stand on small footholds. The best thing is that they are very comfortable, the best-known climbing shoes for beginners.
