Lululemon Athletica, the fast-growing sports apparel company based in Vancouver, has leased a 28,000-square-foot office space south of the border in Portland, Oregon, the sports footwear cluster of the U.S., to help prepare the launch of its first footwear line, according to the Portland Business Journal. The usually well informed newspapers says the office will accommodate designers, engineers, product managers and other experienced people, many of whom have worked for Nike, Adidas or Columbia Sportswear. Lululemon has indicated that its first branded footwear line should come out early next year.
