Profits at Sportswear giant Nike jumped 60% in the three months to February as the weak dollar boosted sales.
Demand for the firm's iconic footwear soared in Europe, with sales up 36%.
But a strong performance in the US also helped the results, which showed profits of $200m on sales of $3bn - up 21% for the best gain in six years.
Nike finally settled a long-running row with distributor Foot Locker, which returned its top-of-the-range shoes to the shelves after almost two years.
That meant wider distribution for the firm's $110 smash hit, the Air Zoom Generation sold with the signature of basketball star LeBron James, as well as other sneakers with a three-figure price tag.
During the dispute over pricing and promotion, Nike had lost ground to arch-rival Reebok.
But it was the dollar influence which may have helped the most.
More than half the overall European sales growth of 36% was the result of currency changes, as dollar fell as much as 11% against the euro during the quarter.
Similarly, half Asia's 21% growth was caused by the weak dollar.
