The Swede-O Passive Night Splint holds the foot at a consistent 90 degree angle to give consistent stretching of the plantar fascia to relieve pain from plantar fasciitis, Achilles tendonitis, and heel spurs.  A foam wedge is included to give an additional five degrees of dorsal flexion, and the soft gray padding gives a comfortable fit throughout the night.  Univerally designed to fit the right and left legs.  Order by Women's and Men's shoe size.
