Fact: Cotton socks are not good for sports. Why? Cotton socks retain moisture when you sweat, which heightens the risk of developing blisters, athlete's foot, or infections. With that in mind, I was determined to find the best non-cotton sock for a day of walking the green, and after a discussion with my pros, I was introduced to the FootJoy Menâ€™s TechSof Low Cut Socks ($12). TechSof Low Cut Sock is a blend of polyester, acrylic, nylon, and Dri-Lex that wicks away moisture and has cushioning in those key areas on our feet where we apply the most pressure.
