Jobst for Men Tall socks have a fashionable ribbed design that delivers effective compression support, yet looks like a men's dress sock.

Special soft micro fibers wick away moisture six times faster than standard nylon, keeping feet cooler and dryer longer. The special formula fights odor by inhibiting growth of fungi and bacteria on the socks. Flat toe seams and roomy toe section provide extra wiggle room.
