The Superstar was the best-selling shoe in the U.S. market in dollar terms last year, based on a ranking publicized in a tweet by Matt Powell, sports industry analyst at NPD. The ranking underlined avid demand for white retro sneakers in the U.S., as well as growing demand for the Adidas brand in the U.S. market. The German brand roughly doubled its market share to about 10 percent in the country last year. However, Nike remains far ahead and the nine other shoes in the top ranking belong to the Nike group, starting with the Jordan XII, Chuck Low, Roshe and Huarache. Powell predicted that demand for sports footwear would focus on technology again once the current, fashion-driven trend subsides.
