  • CoolFlex Achilles Pad & Tongue: CoolFlex padding contains a latex free elastic fiber to provide superior comfort along the Achilles tendon and top of the foot. The shoe lace is attached to the tongue to ensure lace is always centered
  • Invisible Seam: For improved comfort and durability, the seam is positioned along the rear portion of the boot
  • Bilateral: Fits both the left and the right foot


  • Inversion or eversion ankle sprains
  • Medial or lateral ankle instability

Does a good job

Haven't found a better ankle support. Bothersome ankles and rubber boots don't mix, but adding the ASO ankle stabilizer does the trick.

Great product

Great product. Worth it.

Jacqueline Dicie
The best ankle stabilizer

I am post-polio. Not a lot of us left. I have to wear ASO ankle stabilizers every day. Both feet. The question is: how long will they last? The material on one of them is already fraying, so…we’ll see.
