Nike Inc said on Monday manufacturing issues pinching sales over the past six months were now behind it, positioning the company to take advantage of surging demand for sports shoes and apparel. Shares of the world's biggest sportswear maker rose 5.9% to $137.90 in extended trading, as it also beat third-quarter revenue and profit estimates. Pandemic-related factory closures last year in Vietnam, where about half of Nike's footwear is made, and the slow return to normal production in the country led to a shortage of Nike, Jordan and Converse sneakers across most markets. All Nike factories in Vietnam are now operational, with total footwear and apparel production in line with pre-closure volumes, the company's Chief Financial Officer Matthew Friend said. However, shipping delays were still a cause for concern for Nike, especially in North America where transit times have worsened, Friend added.
