Legs and feet react differently, and have different needs during running, so these new Thorlos Experia Energy Ultra Light Running Compression Socks address those needs, with triple-zone compression engineered to create specific and differentiated compression gradation, placing the most intense compression in the foot and ankle area. As with all compression, the intensity decreases across the lower leg and up to the calf. The fabric of these US-produced socks includes Thor-wick Cool to move moisture quickly away from the skin. CuTEC® Copper Ion Technology has been permanently incorporated into the fibres, delivering anti-odour and antibacterial properties. At the mid-foot, arch wraps support the plantar fascia tendon, while a stabilising ankle wrap reduces ankle strain and turn. More padding is placed at the heel to reduce impact, and at the Achilles tendon eliminating rubbing and chafing while also functioning as a heel lock. Lightweight toe pads provide forefoot impact protection and an optimal no-slip fit, helping to protect against blisters, while ventilation in the toe box keeps your foot cooler and more comfortable.
