The Brunners caught the tennis bug after emigrating to the United States, and built the brand around the Classic, the five-striped all-leather tennis shoe that became its calling card. In the 1990s, marketing campaigns like "I Wear My K-Swiss" pushed it onto young urban feet, and a 2007 rebrand around Anna Kournikova played up its tennis heritage.
Ownership has moved widely — Korea's E-Land in 2013, China's Xtep in 2019, and KP Global in 2024 — and the brand later leaned into a mission to "make sneakers for entrepreneurs," with collaborations including Gary Vaynerchuk. It is now based in Glendale, California.
