Soccer shoes need to be very tenacious and light-weighted, so the design is inspired from both Chinese philosophy of Tai chi and the silkworm cocoon. Tai chi is composed of masculine and feminine elements; these two elements are totally different yet can be combined and work interactively as a whole. The inner and outer parts of the shoe have different functions and the athletes may use them differently to make various movements, maneuvers and shootings accordingly. On the vamp we give it a special texture of many fine lines, which twist on the vamp just like the silk on the cocoon. We adopt lighter materials to achieve durability.
