Professional Men's Dress Socks Black - Size 10-13 - Machine Washable - 12 Pack

Stay-Up Technology We tested over 97 different tension levels when trying to find the perfect one. What we landed on is the perfect balancing act between tight enough to never-ever slip down during everyday wear, while free enough to never feel tight or leave any kind of imprint.
Sure-Fit Cuff Our specially-designed cuff stretches not just outward, but also vertically, to perfectly contour to your leg and comfortably stay right in place, while never sliding down.
Seamless Toe We took the extra time to link the final seam on every pair of socks, creating a fully-smooth sock with no annoying bump.
