【With Hard Guards】Equipped with original hard guards placed on the left and right sides to firmly suppress inward and outward ankle inversion. By protecting the entire ankle, it stabilizes wobbly ankles. 【X-shaped Belt】Based on the theory of lifestyle taping, the strong compression knitting applied in a cross shape to the ankle area tightens firmly in opposite directions (up, down, left, and right), supporting ankle protection and stability. 【Adjustable Tightness】Made with stretchy material that expands up, down, left, and right, so you won't feel any discomfort when wearing it. You can adjust the tightness by changing the position of the Velcro on the surface. 【Highly Breathable Type】Adopts breathable dry mesh knitting, making it less prone to stuffiness even when worn for long periods, and allowing for comfortable, dry use. This product is recommended not only for summer but also for those who suffer from itching caused by stuffiness from supporters. 【Comfortable to Wear】The open-heel structure and a triple-layer construction using mesh fabric on the skin side suppress stuffiness and stickiness. It has excellent fit and elasticity, supporting smooth walking. Also, it doesn't get in the way when wearing shoes. I bought this because my 6th-grade child sprained their ankle, but they refused to wear it. It has been opened, but it's new and unused as it was only worn once. Only those who understand this are welcome to purchase.
