Appropriate for high temperatures and humid climates, where breathability and rapid absorption of perspiration are essential. Made with bio-based Natex yarn that dries 50% faster than traditional synthetic materials and reduces odour. The Cool Air Flow system helps keep the foot ventilated. Anatomical design with Target Compression Bandage technology supports the arch to reduce foot fatigue; the absence of the elastic cuff promotes blood circulation while allowing the sock to remain in the right position.
