Therapeutic AND Comfortable…The Plantar FXT is the ideal alternative to cumbersome Night Splints. With its low profile, comfortable design, the Plantar FXT pulls the toes back comfortably stretching the Plantar Fascia. More user friendly than most Night Splints on the market, the Plantar FXT may also be worn during the day to provide longer per day treatment times. Made of Thermoskin’s patented Trioxon lining, the Plantar FXT increases the subcutaneous skin temperature (2-3 °F) allowing for optimal heat therapy and blood flow to the tissue. The spiral structure of the Trioxon lining lifts moisture away from the skin and traps air within the lining to prevent excessive perspiration.
