The original ASO ankle stabilizer provides excellent support, comfort and durability with angled stabilizing straps that contour above the malleolii, CoolFlex™ padding in the tongue and on the inside of the boot along the Achilles tendon and an invisible seam at the rear portion of the boot. In addition, the ASO boot design has been upgraded for a better fit around the heel. The ASO is bilateral and fits either the left or right foot. Indications include: inversion or eversion ankle sprains and medial or lateral ankle instability. PDAC Verified (Colors: BLACK, WHITE) (Fits: Left or Right)

The EVO ankle stabilizer is an evolutionary step forward in ankle protection with its internal stirrup strap, external stabilizing straps and dynamic cuff. This patent pending design enables the EVO to comfortably provide superior support to the original ASO and better protection against high ankle sprains. The dynamic cuff and lining materials have been upgraded to better conform to the ankle above the malleolli and resist distal migration. The EVO is bilateral and fits either the left or right foot. Indications include: inversion or eversion ankle sprains, syndesmotic ankle sprain (high ankle sprain), subtalar joint instability, and media or lateral ankle instability. PDAC verified (Colors: WHITE, BLACK) (Fits: Left or Right).

The ASO with Plastic Stays has the same great features as the original ASO along with the addition of medial and lateral plastic stays to provide enhanced proprioceptive support. The plastic stays are secured in a fully padded pocket and are easily removable. The ASO with Plastic Stays is bilateral and fits either the left or right foot. Indications include: inversion or eversion ankle sprains and medial or lateral ankle instability. (Colors: WHITE, BLACK) (Fits: Left or Right)
