 Shares of Nike are falling after hours after the athletic apparel maker reported lower revenue in its latest quarter after seeing a significant drop in sales in its key footwear business in North America. The company says its results highlighted challenges that led the company to adjust its outlook for the fiscal year ahead. Shares of Levi Strauss fell over 15%. The jeans maker's latest quarterly revenue results fell short of analysts' expectations and not even news of a dividend increase could lift its shares.
