Along with its innovative design, it offers us maximum comfort thanks to its composition based on long-fiber combed cotton, anti-allergic and with a high moisture absorption power. This natural fabric prevents the accumulation of static electricity and avoids the appearance of friction and bad odors thanks to its treatment with silver ions. It incorporates Sanitized, permanent antibacterial treatment that prevents skin infections. The outer structure of the sock with greater friction is reinforced with an extra contribution of polyamide (greater resistance), and lycra (greater elasticity) and its vertical fastening system ensures that the sock fits firmly without pressure. COMPOSITION: 67% Cotton, 18% Polyamide, 6% Lycra, 9% Elastane
