This is the "D.I.Y Collection," which allows you to customize your shoes to your liking by cutting along the stitching, like SK8-HI ⇒ SK8-MID ⇒ SK8-LOW. The exterior features a simple black and white color scheme with checkerboard patterns on the inside. Following the theory, you can change the height, or you can have fun by cutting it partway. I think this is a rare model with limited domestic distribution!
