The OCS OrthoPro™ Stretch Night Splint with Tread holds the foot in a user-adjustable dorsiflexion throughout the night to give comfortable stretching of the plantar fascia, calf muscles, and Achilles tendon. As recognized by podiatrists and orthopedists, the sustained stretching afforded by night splints has been clinically shown to help relieve pain from plantar fasciitis. The plush padding is treated with Kool-Wick and Bacti-Ban to keep you dry and comfortable. Specially designed for nighttime use, the non-skid bottom gives firm footing for those unscheduled trips during the night. A foam toe wedge is included and can be used if toe dorsiflexion is recommended. Fits right and left foot. Order by Women's and Men's shoe size.
