AirForm Night Splint combines light-as-air comfort with therapeutic results. This innovative plantar fasciitis night splint is smaller and lighter (only 9 ounces) than most, delivering both nighttime comfort and morning pain relief with ease. Designed to maintain your ankle in a neutral position (right angle, as if standing) and provide a passive stretch to the Achilles tendon and plantar fascia by pulling from above, gently lengthening tendons while you sleep, while leaving the heel exposed and keeping the foot cooler. An air-filled pad lines this anatomically molded splint at your ankle and foot juncture, providing a cushioned fit. Two adjustable hook-and-loop closures adjust to fit. Note: Intended for nighttime use only. Fits left or right foot. Material Content: Plastic shell: 100% ABS plastic. Padding: 100% polyester and urethane foam. Laminate Binding: 100% polyester. Straps: 100% neoprene with polyester fabric. Care: Hand wash only with warm water and mild detergent. Remove excess water and air dry. Imported.
