The U.S. Rubber Company came up with more comfortable rubber sneakers with canvas tops called Keds. Keds set up in America to sell rubber soles which was created from a newly developed process called vulcanisation which is still in use today. It uses heat to meld rubber and cloth together.
Keds mass produced their sneakers. They got nicknamed sneakers by Henry Nelson McKinney, an advertising agent, because they were so quiet, a person wearing them could sneak up on someone.
