The number of Foot Locker stores outside the U.S. rose last year by 1.8 percent to 732, with those located in Europe rising to 604 from 590. According to the group's 10-K filing with the U.S. Securities Commission, sales per square foot rose in its stores by 3.9 percent to $460 last year, and they were 38 percent higher than in 2009. The report shows that 68 percent of the Foot Locker group's purchases came from Nike in 2013, up from 61 percent two years earlier, with each division buying between 39 and 80 percent of the goods from the Swoosh. The second-largest vendor – presumably Adidas – accounted for 15 percent of purchases. Together, the four largest brands supplied 88 percent of the merchandise sold in its stores, compared with 82 percent in 2011.
