Merino wool has many great, and natural, benefits for sports activity socks – it’s soft, its breathable and its warm - but left to its own devices, wool also enables an extremely high rate of bacterial growth. Switzerland’s X-Socks have tackled this shortfall, bringing extra hygiene, freer air circulation and enhanced comfort to their X-Socks Air Step Trekking Socks by developing and using several smart textile technologies.With left/right specific, anatomically shaped footbeds for targeted cushioning and protection, their ultra-light, breathable and hypoallergenic Mythlan™ fibre actively reduces unwanted bacteria growth, with Merino wool providing the warmth. Special AirGuide and AirConditioning channels create continual air circulation.X-Socks Air Step Trekking Socks provide protection at every vulnerable zone of the foot and leg, with the X-Cross Bandage for ankle stability, targeted padding, Activ-Bund perfect hold cuffs and flat toe seams to avoid uncomfortable blisters forming.
