Soap Shoes are shoes mae for grinding. They were introduced by Chris Morris of Artemis Innovations Inc. with the brand name "Soap" in 1997 and simultaneously invented a new extreme sport based on Aggressive Inline Skating. They have a plastic concavity in the sole, which allows the wearer to grind on objects such as pipes, handrails, and stone ledges. The company and their product rapidly gained popularity through numerous fansites, a video game, and live demonstrations across North America and Europe soon after, but fell to legal vulnerabilities and was readministrated twice, eventually bringing the brand to Heeling Sports Limited. The act of grinding on rails and ledges specifically using soap shoes has been dubbed "soaping," with the "soaper" being the one performing said act.
