The Lorpen PRUC Pro Ultra Run Crew socks are designed for long-distance trail running, featuring a mid-height crew that provides protection and comfort during training.This product stands out for its three-layer construction that prevents blister formation and odours, thanks to the combination of technical and natural fibres. They include a thin padding throughout the sole that cushions impacts without sacrificing the feeling of lightness when worn with shoes. Additionally, their design is intended to offer a perfect fit and high breathability, adapting to different weather conditions and terrains.They are made from high-quality and sustainable materials, such as RWS-certified Merino wool, which provides thermoregulating and anti-odour properties, and RED-CYCLED recycled nylon, which helps reduce textile waste. The inclusion of COOLMAX® ECOMADE ensures quick drying and maximum ventilation, while LYCRA® fibre provides elasticity and recovery for an optimal fit.
