The Point6 fit is quickly becoming legendary. The deep heel pocket hugs your heel and prevents tightness across the instep. Our toe closure is the ultimate in smooth. Your toes won't feel any lump or irritation. Cross stretch is one of our secret weapons in creating a sock that is tight enough to stay up, but not too tight to impair circulation. Add just the right amount of terry loop cushioning where needed, ventilation zones where desired and the result is a kick-ass, bad-ass sock. 54% wool/ 43% nylon/3% spandex. Extra light cushion underfoot. A favorite of avid runners.
