The Footprint Shin Socks in Charcoal are fp "painkillers". Welcome to the end of shinners and ankle bruises. This is a shin/ankle gaurd. A new type of of nano technology, the fabric in this sock is permanently embedded with bamboo charcoal. Bamboo charcoal is antibacterial and anti fungal. Bamboo charcoal emits far infared rays and negative ions which penetrate the skin and increase oxygen delivery to cells which is known to increase cellular function and can result in less foot fatigue and faster recovery times.
During normal use, the special foam in these socks is soft, custom fitting and not noticeable. However, at the moment of impact, it becomes a hard protective shell and protects your body so you can focus on tricks, not on pain.
