Designed to recreate the 'barefoot environment' with all-round air conditioning, and protect with a soft cocoon of protective, targeted cushioning, the ladies X-Socks Trekking Light & Comfort Socks are foot-to-calf constructed for all types of mountain climbing, trail trekking and lengthy walks through woodland, assuring perfect comfort each and every time. The left/right anatomical foot shape is a special 'NarrowArrow™' construction, making these socks ideal for the female foot, with a broader forefoot, slender, higher middle and narrow heel bone, preventing wrinkling and minimising pressure points. A high performance fibre mix allows the socks to be robust, yet cashmere-soft; moisture-repelling and protective, using patented Xitaloft, Pneumaloft nano-fibre, which out-performs all comparable natural materials, and hollow-core Robur for light, effective cushioning. Shaped padding on the calf, shin, Achilles' tendon, ankle bone, instep, toes, toe-tips and heel protects against shock, pressure and friction. Every step you take, the AirFlow and AirConditioning Channel® design allows moist, overheated air to be pumped out of the shoe for dry, cool feet. X-Socks Trekking Light & Comfort Socks are perfect for treks in any weather and on any terrain, day in and day out.
