Run Ultralight Tab is our lightest-knit running sock, built for runners who want breathable foot coverage, immediate shoe connection, and high responsiveness across varied terrain without excess cushioning. The nylon-blend construction delivers a low-bulk feel while supporting all-day breathability. Infiknit™ reinforcement is built into the heels and toes—the highest-wear zones of a running sock—to improve durability where abrasion typically starts. Freshtek™ provides moisture and odor control to help manage sweat during repeated wear. Performance Mesh increases airflow through the sock structure, while Channeled Air Cushioning adds targeted cushioning without turning the sock into a thick, padded fit. Performance Arch Support helps secure the sock around the midfoot for a more stable in-shoe feel, and the Seamless Toe Closure removes bulky toe seams for smoother forefoot comfort in snug running shoes. The tab profile adds heel coverage at the shoe collar, and the reflective logo helps return light when illuminated in low-light conditions. For value, this sock combines reinforced wear zones, breathable mesh, moisture and odor control, arch support, seamless toe construction, and ultralight running performance in one pair. Every pair is backed by our All Good Guarantee.
