ADJUSTABLE ANGLE: Plantar Fasciitis Splint Night relieves the pain and discomfort of plantar fasciitis and Achilles tendonitis at night. By adjusting the angle at which the aluminum strips are inserted, you can vary the tension placed on the plantar fascia. (85-90 degrees) Product Highlights: This plantar fasciitis night splint offers two aluminum bars. If your fasciitis symptoms are mild, a thin aluminum rod is recommended first. If you feel the effect is not obvious, try thick aluminum strips. The plantar fasciitis branch has two straps that pull the toes up and the foot into a slight dorsiflexion position. Other brands have only one strap. Who to use: This plantar fasciitis reliever is available for both men and women and is suitable for your right or left foot. You can also try wearing the splint for 1 hour at a time before going to bed and then try to wear it throughout the night. BETTER RESULTS: Relieves pain caused by plantar fasciitis, flat feet, heel spurs, high arch aggravation, and relieves arch pain and heel pain caused by prolonged standing and walking. PREMIUM MATERIAL: Made of breathable, lightweight elastic tricot material, this footrest is designed with soft padded foam and supported by a bendable aluminum bar at the instep. Give you a comfortable wearing experience and relieve your pain. It can be worn day and night, allowing you to sleep comfortably throughout the night.
