Invisible but highly functional. The new UYN Ghost 4.0 sock offers comfort, breathability and protection for everyday activity. The cotton fabric leaves a pleasant sense of freshness and softness on the skin, the use of Fibresist yarn in the toe and heel increases abrasion resistance. The attention to detail results in superior comfort: the inner surface with micro Terry loops facilitates impact absorption, the non-slip insert on the heel and the elastic band in the middle of the sock improve stability.
