Kasina is a brand founded by former professional skateboarder EunHyuk Lee in 1997 and enjoys a high reputation in the field of Korean street fashion. The design of this collaboration with NK also conveys that Kasina's "travel" is inspired by the transportation elements in this "travel". The blue version also draws inspiration from Korean transportation in the 1980s. The color is derived from the appearance of the old Seoul bus, and the unique tag on the shoe side represents the steering wheel.
