Full product description

The OS1st Thin Air Performance No Show Socks (3‑pair pack) are built for runners and active walkers who want the thinnest possible sock without sacrificing cushioning, protection, or comfort. Using OS1st’s TA4 Thin Air technology, these socks feature ultra‑thin “Skin Thin” zones on the top of the foot with uniquely positioned lift bars that maximize air flow and help release heat, keeping your feet cooler on long runs and hot days.

A lightly cushioned bottom and 4 zones of graduated light compression provide a secure, supportive feel while still staying low bulk inside performance footwear. The no‑show design includes a higher heel tab and deep heel pocket to help prevent slipping, bunching, or pinching, so the sock stays in place as you move. Made with soft, durable microfiber yarns and moisture‑wicking, anti‑bacterial properties, Thin Air Performance socks help reduce blisters, friction, and odor, making this 3‑pair pack ideal for everyday training, races, gym sessions, or casual wear.
