GoldToeMoretz wants to sock it to the competition. It makes socks for sporting goods stores and retailers, such as Gap, Target, and Old Navy, and offers private-label services for companies including Cherokee, Faded Glory, and Pro Spirit. It peddles the PowerSox brand -- a heavy hitter in performance socks -- as well as Gold Toe. GoldToeMoretz has licensing agreements with the likes of New Balance and Under Armour and ships some 360 million pairs of socks annually. Founded in 1946, Moretz was bought by The Blackstone Group for $400 million in 2006; it later merged with 90-year-old Gold Toe to form GoldToeMoretz and become the top US sock maker. Looking to pair up, Gildan Activewear acquired the company in 2011.
