For decades flip flops have had a bad rap among foot doctors. Many doctors still believe that flip flops are flimsy, offer no support, and put extra strain on lower body muscles and joints. There is, however; a growing recognition in the medical community of the distinction between healthy flip flops and unhealthy flip flops. Several podiatrists and foot care experts have even taken it upon themselves to step up to the challenge of designing a truly healthy, therapeutic flip flop. Vionic flip flops - created, approved, and recommended by podiatrists - are one of the most medically respected orthotic flip flops on the market today.
