Designed with a Muscle Support System, the Zone3 Calf Guards are built to reduce muscle vibration and improve shock absorption. Preventing injury, calf guards work to prevent muscle tears, cramping, shin splints and impact injuries. Post-exercise, you can expect quicker muscle repair and recovery times allowing you to train harder and reduce fatigue. Made from a high-wicking fabric, you can be sure to stay cool and dry and the 360-degree seamless construction eliminates chafing so you stay distraction-free and focused.
