The Drymax Run Hyper Thin No Show Socks are specifically designed for women ultrarunners who prefer a lightweight and minimalistic sock. These socks are made with a blend of Drymax and polyester fibers, offering excellent moisture-wicking and quick-drying properties. The thin construction provides a barely-there feel while still offering blister protection. The anti-slip wedge prevents the sock from slipping down during long runs. With their lightweight design and moisture-wicking capabilities, these socks are a popular choice for women's ultrarunning.
