The ASO ankle stabiliser brace is a lace-up ankle support designed to hold the ankle steady and limit inversion, the inward roll of the foot. Non-stretch stabilising straps wrap in a figure-8 pattern that works like an ankle taping application, locking the heel in place. It sits low enough to fit inside a normal athletic or street shoe, and the straps retighten during wear without taking the shoe off. The brace fits either the left or right foot and comes in black, sizes XXS to XXL.
