They feature specially sculpted pads in the front and rear to ensure maximum comfort during all your favorite activities. Engineered to provide activity-specific protective padding, Thorlos Experia® socks provide blister-free comfort and protection. Designed for high performance runners, cyclists, hikers, and fitness walkers, these socks generally appeal to individuals who prefer a minimal amount of foot protection. By utilizing THOR•WICK® COOL, a high-performance moisture management fabric, these socks effectively move moisture away from the skin, keeping you cool, dry, and comfortable. The socks offer an aerodynamic fit and protection without added weight, suitable for running and multi-sport activities. An ultra-lightweight sock frame made of lycra mesh provides a contoured, aerodynamic glove-like fit and maximum breathability. Specially sculpted Thorlo pads in the ball and heel provide protection from shear and impact in critical strike or impact zones. A lightweight Achilles tendon pad protects against rubbing and chafing, while also functioning as a heel lock. Made in the USA | North Carolina.
