Virgin wool-rich sports socks for runners who want the best mix of natural and performance synthetic fibres. Falke RU4 Cushioned Wool Sports Crew Socks are comfortable, ideal for keeping muscles ready for action by retaining warmth, yet the fabric structure is effective at thermal-regulation and moisture management for an optimal skin environment. These anatomically shaped socks have a perfect left/right fit, placing low bulk medium cushioning where it is most needed for running, at the toes and heels to provides protection against impact and blisters. Comfort tops and flat seam wrinkle free toe areas resist painful pressure marks, and foot arch shaping supports the foot whilst in motion.
