The 1000 Mile Approach Repreve Sock is a high-performance sock designed for outdoor enthusiasts who value comfort, durability, and sustainability. Made with Repreve, a recycled fiber created from post-consumer plastic bottles, these socks offer a combination of eco-friendliness and technical excellence. These socks are perfect for hiking, trekking, and other outdoor activities thanks to their advanced features. The sock's unique design incorporates a combination of cushioning and ventilation zones, ensuring optimal comfort and breathability. The cushioning zones provide support and protection in key areas, such as the heel and toe, while the ventilation zones allow for enhanced airflow, reducing the risk of sweaty and uncomfortable feet. Outer Layer: 42% REPREVE® Nylon 6, 20% wool, 18% acrylic, 18% polyamide, 2% elastane. Inner Layer: 99% REPREVE® Nylon 6, 1% elastane. The crew length 1000 Mile Approach Sock is designed for maximum comfort with today’s technical approach footwear. The inner layer stays with the foot, wicking away moisture, whilst the outer moves with the shoe, reducing friction and helping to prevent blisters and reduce wear. The unique combination of fibres maintains a comfortable temperature for the foot, making this the perfect warmer weather outdoor activity sock to wear with lightweight boots as well as approach/trail shoes and sandals. Features: Arch bracing for additional support and custom fit. HeelPower design grips the heel firmly in place – so no slippage! Double layer construction eliminates friction between foot and shoe, reducing wear and helping to prevent blisters. 71% Recycled Content.
