Nike's global sales are booming. The company's revenues rose 11 percent in its March-to-May quarter compared to a year ago, Nike said Thursday.

Nike is outfitting 10 teams, including the US team, during the World Cup. The company introduced four new soccer shoes in the lead-up to the tournament, and more World Cup athletes are wearing Nike shoes than those of all other brands combined, Nike President Trevor Edwards said in a call to investors.

A third of the tournament's players are wearing Nike Magista cleats. Nike's soccer-related sales grew 21 percent during the fiscal year to $2.3 billion (1.7 billion euros).

Most of the growth was in Europe and in emerging markets, while growth was weaker in the US and China.

Nike's global net income rose just 5 percent, with the difference in gross and net income reflecting Nike's heavy expenditures for marketing in connection with the World Cup soccer tournament.

The company's three-month net income rose to $698 million (512 million euros), or 78 cents per share, compared to 76 cents per share a year earlier.

Nike is increasingly grabbing market share in soccer equipment - a segment of the sports gear market in which German firms Adidas and Puma have traditionally been strong.
