The Carhartt Force Extremes Cushioned Ankle Work Sock is one of our fastest-drying socks. 37.5 Technology particles are naturally embedded in the yarn, and will never wash out for the entire lifetime of the socks. Force Extremes uses your body's energy to speed up the conversion of moisture to vapor, keeping you dry and comfortable during your daily grind. Force Extremes increases your comfort and performance in a wide range of conditions, from hot to cold, so you can stay dry and on the job longer without having to switch out your socks. The fully cushioned foot provides extra comfort, and the ribbed, elastic ankle brace and arch support ensure socks stay in place. A reinforced heel and toe delivers extra durability where you need it most; so you can count on these cushioned socks lasting as long as your favorite footwear.
