When its time to start baring forearms and knees, it's time to switch to the thinnest, best wicking, most breathable socks in your sock drawer. Giordana has designed the EXO Men's Mid Cuff Sock to occupy that spot in your clothing matrix. The sock is woven from a blend of Meryl Skinlife and Lycra. The Meryl is there because the fiber is light, thin, fast-wicking, and quick-drying. The Lycra is there to keep it snug, both around your feet and your ankles. To keep it super snug around your feet, there's a mid-foot band; sliding socks are no fun, not only can they be annoying, they can chafe. The Giro Men's EXO Mid Cuff Sock has a cuff height of 2. 5 inches. The socks are left and right specific. Sizes run from Small to Large.
