Nike Inc (NKE)

Thanks to Nike, that swoosh symbol is about as ubiquitous as oxygen. The Oregon-based company sells shoes (duh), sports apparel, athletic bags, socks, eyewear, watches, swimwear, cycling apparel, and accessories. And you knew all of that, but we're guessing you didn't know that Nike also sells a line of dress and casual footwear, under the brand names Cole Haan, G Series, Bragano, and the classic Converse Chuck Taylor sneaker line.
