MedSpec ASO® Vortex® Ankle Stabilizer
Vortex® does not have a boot; instead it has an upper cuff member that has been
upgraded to better anchor around the malleoli. The stabilizing straps are the only
materials that spiral around the foot inside the shoe. The Vortex is bilateral and fits
either the left or right foot. Indications include: inversion or eversion ankle sprains
and medial or lateral ankle instability.
