The Matthew M. Williams x Wmns Free Trainer 3 Flyknit SP is a collaboration between the renowned British designer and Nike. This particular edition, known as the 'Light Bone' colorway, was unveiled in June 2019 and is designed to cater to the needs of a modern lifestyle. The shoe boasts a ribbed knit bootie that is strengthened with molded synthetic overlays, along with a suede heel and a textile shroud. What sets this model apart is its detachable crampon rubber sole, which not only offers lockdown with tonal straps but also showcases Vibram technology for enhanced versatility and support on both indoor and outdoor surfaces.
