ASO Ankle Brace Review 2019

Updated January 11, 2019

ASO ankle stabilizers are the number one choice of sports medicine professionals the world over. ASO stands for Ankle Stabilizing Orthosis and offers a superior method of support than strapping or wrapping with tape. That’s why it’s been chosen by over 250 universities and pro teams throughout the USA.

In this article, we go in depth on the four premiere sellers in the ASO range, and then compare them with the best of the rest on the market.

The Best of the ASO Range

ASO began with just a single innovative ankle brace. They have now extended their range to cater for every market segment. In this section, we review their four most popular products:

In the following section, we compare three popular ASO alternatives; ACE Deluxe Ankle Brace, Active Ankle T2 Brace and the Shock Doctor 851 Ankle Brace.

#1. ASO Ankle Stabilizer

ASO Ankle Stabilizer

The ASO Ankle abilizer is the original ASO product. It features nylon stabilizing straps which place a restriction on inversion or eversion ankle motion, movements which often lead to injury, especially when running. The ballistic nylon boot construction makes this an extremely durable, yet lightweight brace. This greatly increases the longevity over other construction materials such as neoprene. The brace is a bilateral design, so can be used on either the left or right foot.

The non stretch stabilizing straps of the ASO Ankle stabilizer simulate the basketweave technique used to apply athletic tape, providing the rigidity of tape, without the hassle. The heel is effectively locked in place to enhance plantar protection. A unique aspect of the ASO is that you are able to retighten the straps at any time without having to take off the shoe. Furthermore, the low profile design makes it suitable for all types of footwear.

ASO EVO Ankle Stabilizer

The ASO EVO Stabilizer has all of the extra support features of the original ASP stabilizer but adds an inner stirrup strap and an ankle cuff. This provides even greater protection against inversion and eversion ankle injuries when running. The dynamic cuff boosts the stability and support you need when you are recovering from an ankle injury. It also allows you to continue training without discomfort. In addition, the inner stirrup strap affords maximum protection against heel displacement injuries.
