Upgrade your sock drawer with the Darn Tough Vertex No Show Tab. Darn Tough designed the Vertex for a distraction-free fit. The seamless construction keeps blisters at bay, and the no-show tab height stays out of sight for a clean look. Darn Tough knit the Vertex from 50 percent Merino wool, 45 percent nylon and 5 percent Lycra Spandex. The combination is moisture-wicking, fast drying and soft to deliver a premium feel and unbeatable performance. With light cushioning underfoot for a thin feel, the Darn Tough Vertex No Show Tab will be the first socks you reach for before your run.
