For heavy-duty work, you need a comfortable, heavy-duty sock. This new quarter crew sock for women is made from a cotton-rich blend with CoolMax® polyester that keeps feet dry and blister free .. all day long. In addition, the mesh-knit instep, arch and ankle panels allow moisture and heat to move out of the sock. It also features anti-odor properties; a reinforced toe, arch and heel; a terry-cushioned foot for comfort; and spandex reinforcement to keep the sock up. The knit-in Carhartt logo says it all: job-tested, dependable, durable.
