Bauerfeind's ErgoPad Ball and Racket supports the foot and ankle during quick stops and turns to relieve pain and help avoid injury. It has been specially developed for match sports and racket sports such as basketball, handball, tennis and squash. Because it provides the necessary stability for the foot during quick stops and turns, it is perfect for ball sports. Its innovative Weightflex core provides gentle support for the foot arches and promotes the natural heel-to-toe movement of the foot. An ergonomically designed X-shape makes the core stable and flexible at the same time. This enables ErgoPad Ball and Racket to support the foot arches without restricting the foot's natural movement. With a thin construction, the insert fits into most shoes. Its heel cup surrounds the heel and stabilizes the ankle during lateral movements, while the sensorimotor spots stimulate the foot muscles and improve motor function and the antibacterial top cover inhibits odors. Give your feet the support they need while you enjoy the sports you love. Material: Fabric, Polyurethane.
