The Royce Medical® Airform® Dorsal Night Splint is recommended for use in reducing pain from plantar fasciitis and Achilles tendonitis by holding the foot in a neutral position throughout the night. The dorsal design supports your foot from above, leaving the heel and arch exposed for maximum comfort and a natural feel while sleeping. This support is convenient to use; simply adjust the foot strap once, slide your foot in, and adjust the calf strap. The air-filled cells and padded straps combine to make this a very comfortable support. Universal fit for right and left legs. Order by Women's or Men's shoe size.
