This model is inspired by the sole of the GEL-EXTREME basketball shoes released in 1989, and has a sole structure that pursues stability against intense movements. The interior is equipped with BLAST FOAM, which has excellent cushioning properties that are also used in running shoes, to provide cushioning against impact when landing. The upper is made of suede material on the outer shell side to increase durability, and the inner shell is made of mesh material for breathability. In addition, the tongue part is made thicker to provide an excellent fit and reduce foot contact when operating the board. The insole is designed to have different hardness on the inside and outside based on skateboard motion analysis, and has punched holes to promote a center of gravity inside.
