MADE IN THE USA: DeFeet products are made with Recycled Poly and/or Merino Wool: We've been knitting our socks and apparel in our North Carolina microsockery since 1992. Engineered to be long-lasting, DeFeet products are sustainably manufactured within a local supply chain. Our wool goods are made from USA-grown Merino and our Repreve recycled poly is manufactured right here in North Carolina from locally collected post-consumer water bottles. OPEN MESH WEAVE: Breathable and Moisture-wicking, designed to keep your feet dry by efficiently pulling moisture away from the skin and allowing it to evaporate. Perfect for athletes, hikers, and individuals whose activities cause their feet to sweat. LIGHTWEIGHT: Designed with a thin profile to provide a minimalist feel. Reduces bulk and enhance comfort while minimizing wrinkles and bunching, ensuring a seamless interface between the foot and the cycling shoe. Promoting better pedal feel and control. NO-FEEL TOE SEAMS: Seamless toe design reduces friction, minimizes the risk of blisters, and enhance overall comfort during prolonged activity.
