INCYLENCE RENEWED 97 sport socks are made from 97% recycled materials, primarily ECONYL® fibers sourced from marine and industrial waste. Manufactured in Portugal, these sustainable running socks provide exceptional comfort and breathability. These odor-free running socks can be worn multiple times without washing. Reinforced areas underfoot, at the heel, and the toes ensure long-lasting comfort. The double-layered wide cuff prevents sweat from entering the shoe, and integrated midfoot compression offers stability. Additional cushioning in the Achilles and heel areas protects sensitive spots, ensuring maximum comfort and durability.
