Quatro socks are ideal for use in spring and summer conditions, and all year round in insulated boots. Ergonomically designed, the Elastic Support System (ESS) locks the sock to the foot, while the wide elastic arch prevents foot compression.

Strategically placed ventilation ribs control moisture management. Sculptured cushioning and reinforcement panels provide foot and leg comfort and offer overall protection.

Serious comfort. Skellerup's range of revolutionary, purpose-specific socks are the result of combining leading-edge technology and premium yarn selections to deliver new levels of comfort, resilience, practicality and longevity.
