We've employed super soft Merino wool and Coralast abrasion resistant fibers to engineer an ultra-comfortable, long-lasting work sock. Revolutionary comfort-stretch top yields to the shape of the leg without falling, pinching or binding for a superior never-know-its-there feel. Compression arch and ankle stabilizers keep socks securely in place. It's a real tough sock with a super-soft side. Men's sizes X-Large (US Men’s shoe size 12-14.5).
