The Lorpen Re-Thermic Midweight Hiker Sock is engineered to keep your feet warm, dry, and comfortable on the trail. Built with Lorpen’s innovative Re-Thermic technology, this midweight hiking sock combines technical fibres with hollow yarn construction to trap and retain heat, making it an excellent choice for medium-level outings on cooler days.

Strategically placed cushioning softens impact on high-stress areas, while reinforced heels and toes add long-lasting durability. The mid-height cut fits securely with hiking boots or approach shoes, offering reliable coverage and a snug fit that won’t slip or bunch, even during long days outdoors.

By effectively managing moisture and locking in warmth, the Re-Thermic Mid Hiker delivers dependable comfort and protection for trekking, backpacking, or everyday hikes in shifting temperatures.
