The more the foot's muscles atrophy and weaken, the more vulnerable the foot is to diabetic complications such as ulcers, fractures, and infections. Nerves and muscles are activated in the foot and not braced. Muscles in foot are naturally strengthened to increase blow flow and circulation. They are soft and comfortable that can treat the root cause of most foot related pathologies rather than treating the symptoms. This product is unique in that it works by stimulating the foot to strengthen itself and naturally creates a strong, functional foundation for the entire skeletal system. This results in an increase proprioception, circulation, balance, a decrease in fatigue and pain, and improved skeletal alignment and posture. This new model of insoles uses Celliant technology for its top textile layer. This material has been scientifically proven to improve circulation using the body's own infra-red energy. For now, the Therapeutic PLUS model is available only in full-length.
