K-Swiss
K-Swiss makes tennis and pickleball shoes and apparel. It was started by two Swiss brothers who moved to California to create a tennis footwear brand; as keen skiers, they drew on leather ski boots to design a supportive leather tennis shoe. Introduced in 1966, the K-Swiss Classic was, according to the brand, the world's first all-leather tennis shoe, and K-Swiss is marking 60 years of tennis and style.
