Tuft's warmest merino sock, with 65% warm merino wool and terry on the inside. A knee-high sock that fits perfectly in the slalom boot, and will keep you warm and comfortable as you go down the slopes. The socks will also be excellent in rubber boots or in high boots - regardless of the area of use, the knee socks will warm you right from the knees to the tip of the toe. To make it easier to distinguish our merino socks from one another in the sock drawer, we have marked the Warm socks with three stripes above the instep. The socks are dark blue with details in burgundy red.
