Sportful calls its new RD Socks the softest sock we've ever made, due to the ultralight composition and generous mesh paneling along the top. The Socks were made from a lightweight Meryl Skinlife microfiber, which is breathable, antibacterial, and works to pull moisture from the skin. Lightweight mesh paneling at the top of the foot works to promote cooling airflow, while reinforced heel and toe areas add light cushioning and durability to the socks. Sportful finished off the socks with a 9cm cuff height, which works to provide both moderate coverage and give your ankles a light amount of compressive support. The Sportful RD Socks are available in sizes Small, Mediumlarge, and X Large, and they come in the colors Black and White.
