Alpinestars ZX v4 Nomex Socks These nomex socks from Alpinestars' advanced ZX base layer series were developed with a compression design for enhanced performance. Gradual compression, sport design wraps around the muscles, tendons and ligaments in the foot, ankle and calf. This aids overall circulation and blood flow to the legs, as well as assists in combatting fatigue.  Lightweight and comfortable, these ZX v4 socks incorporate elastane fiber for comfort and freedom of movement.  The latest version helps reduce pressure points, making them more comfortable for day-long stints in the car. Soft to the touch, the seamless construction is designed to reduce pressure points. The FIA 8856-2018 homologated socks fit to just below the knees for maximum protection. ALPINESTARS ZX V4 NOMEX SOCK PROTECTION Certified to the new SFI homologation standard.
