Experience the AF7® Ankle Bracing Sleeve

Introducing K-Zone® Technology (KZT®) a breakthrough design that provides the support of a kinesiology taping treatment without the inconvenience of its temporary and binding nature. Using a hypoallergenic gel stabilizer system with high resistance fabrication zones, KZT® creates a strapping type effect in specific areas to steady and help secure supportive joint structures. The result is stabilization without immobilization. Proper medical-grade compression in combination with KZT® provides a slip-on therapy solution for use whenever you need it. KZT® is found in the newest OS1st® product, the AF7® Ankle Bracing Sleeve.
