You know you can count on a shoe brand to be comfortable when its founder is a podiatrist. Created by Beverly Hills-based Dr. Sylvia in 2008, Planet Flops were first introduced to the doctor's clientele—but it wasn't long before she decided to make them available worldwide. In an array of versatile hues and styles, Planet Flops flip-flops are made with natural rubber, guaranteeing a firm, comfortable fit that magazines like Shape swear by.
