The ASO Vortex delivers the proven technology of the figure-eight stabilizing strap in an ultra low-profile design, making it the ideal stabilizer for those athletes or patients that will not tolerate any bulky materials inside their shoe. Low Pofile DesignThe Vortex does not have a boot. It only has an upper body member, stabilizing straps, and an elastic cuff. The stabilizing straps are the only materials that spiral around the foot inside the shoe. Stabilizing StrapsNylon stabilizing straps form a complete figure-eight to help stabilize the subtalar and talocrural joints. Stabilizing straps are angled at the attachment to better contour above the malleoli for enchanced comfort and migration resistance. Upper Body MemberUpgraded upper body member now has four eyelets and an internal plastic rib to better anchor the stabilizing straps around the malleoli and resist distal migration.
