The ViscoSpot Heel Inserts are shoe inserts designed for use by individuals with lower extremity disabilities or plantar fasciitis. Made of dual-density, medical-grade silicone, these inserts reduce shock loads to the heel. A softer, blue silicone spot on the medial side of the heel cushions the precise area where plantar fasciitis pain occurs. The extra height gently lifts the plantar fascia and decreases stress on the tendon. SIZES: Men's 6 to 6.5 and women's 3 to 8 or men's size 7 or larger and women's size 8 or larger. COLOR: Clear with blue spot.
