This style of footwear also became prominent in America at the turn of the 20th century, where they were called 'sneakers'. In 1892, the U.S. Rubber Company introduced the first rubber-soled shoes in the country, sparking a surge in demand and production. The first basketball shoes were designed by Spalding as early as 1907. The market for sneakers grew after World War I, when sports and athletics increasingly became a way to demonstrate moral fiber and patriotism. The U.S. market for sneakers grew steadily as young boys lined up to buy sneakers endorsed by football player Jim Thorpe and Converse All Stars endorsed by basketball player Chuck Taylor.
