Nike's online sales in North America drove quarterly profit and revenue ahead of Wall Street estimates and led the world's largest athletic shoe maker to forecast better than expected sales for the year. 

Nike's brick-and-mortar sales have fallen since the Covid-19 pandemic began, as shopping centres and department stores were closed around the world. 

To combat that, the footwear maker has turned its focus to direct-to-consumer sales, especially through its own website and apps. 

The brand's digital sales surged 82% in the first quarter ended August 31, with at least double-digit rises recorded in all regions.

In the previous quarter, Nike reported a 75% increase in online sales - nearly a third of total revenue, a goal Nike had previously set for 2023. 

"We know that digital is the new normal. The consumer today is digitally grounded and simply will not revert back," Nike's chief executive John Donahoe said. 

Nike said it expected fiscal full-year revenue to rise between high single digits and low double digits versus last year, saying second-half sales would be "up significantly," even though first-half growth would be flat. 

Analysts forecast a fiscal 2021 sales rise of 5.9%, according to Refinitiv IBES. 

US retailers including Foot Locker and Dick's Sporting Goods - which canceled shipments in the early days of the pandemic - have begun making orders for inventory in the second half of Nike's fiscal year, analysts say. 

Earnings before interest and taxes rose 18% in North America, Nike's biggest market, with footwear sales up 11% to nearly $3 billion. 

Nike's latest results are a far cry from those of just a quarter ago, when Nike reported a surprise loss of $790m as retailers canceled orders and people kept away from Nike stores in key markets like North America, Europe and China. 

Shares in the Oregon-based company have risen 16% this year. Nike has gained favour among shoppers this year with investments in marketing itself as a socially conscious company, prominently supporting movements like Black Lives Matter and Time to Vote. 

First-quarter sales in China, where the economy opened from lockdowns much earlier than in other parts of the world, rose 6%, led by factory stores and online sales. 

The company said its net income rose to $1.52 billion, or 95 cents per share, from $1.37 billion, or 86 cents per share, a year earlier.
