Windproof, waterproof, flexible! This sock is meant to be used where most others fail. Rain, snow and mud are its elements. That's where it comes into its own. It protects your feet from all weather conditions and keeps you warm even in the worst conditions. The Running Lite socks are lightweight, feature an elastic ankle support and an elastic arch band, combined with next-generation drirelease® DriFil yarns and are designed to provide optimal performance in foot protection and support when running in wet, muddy and cold conditions.
