Over the years, the Superstar has remained popular, partly because it's so easy to wear. It might have gotten its start as an athletic shoe, but it doesn't look like an adidas basketball sneaker, as far as current standards go.
A superstar is someone who's either very famous or extremely good at what they do. Legendary baseball player Babe Ruth was the first person called a superstar in print, around 1920. You might think of a superstar as a popular musician, like Taylor Swift, or maybe a famous actor or well-known athlete.
