FP MFG Painkillers socks are embedded with Artilage (Artificial Cartilage Foam) in the shin and ankle bone areas to protect from shinners… Artilage is a unique type of memory foam that becomes firm when impacted therefore allowing the socks to be comfortable and form fitting like a normal sock while still being very protective.
