K. SWISS Casesis is an American brand, but it was originally launched by two Swiss people in the USA with a dream of making shoe makers. This case chair started from the place of creating tennis shoes, but its characteristic 5-strand lines were made to prevent the shoe from stretching during intense tennis play. In the tennis shoe industry where canvas was normal at the time, all leather shoes became a talk of talk about it. In Japan, it has a high reputation for leather sneakers, and is known as case chair.
