Matthew M. Williams first collaborated with Nike at the Paris Fashion Week in June last year, and immediately attracted great attention from the outside world. The whole shoe is titled Nike Free Trainer 3.0. In addition to the sock-style high-top design, there are plastic stabilizers on both sides of the shoe body. The conspicuous Swoosh Logo and zippers can also be seen on the inside. In addition, the biggest highlight is naturally the detachable Vibram outsole with straps, which exudes a strong functional atmosphere.
