Foot Drop, Plantar Fasciitis, Foot Inversion Correction, Ankle Dorsiflexion Support, Ankle Brace, Free Size, One Leg Thank you for viewing! Only used once indoors for a trial (almost new). It has a sturdy construction, so it provides a good amount of support. Adjustable with Velcro, so it's free size, unisex, and can be used on either the left or right leg. The same product is also listed in another window, and you can use it on both legs by purchasing them together (discount available). No smokers or pets, but it's a home-stored item, so we look forward to your purchase if you don't mind.
