Nike has released the Nike Classic Cortez KM QS (11,000 yen), a shoe based on a product prototype by Bill Bowerman, which will go on sale from August 11th.

In 1965, long-distance runner Kenny Moore, while playing for the University of Oregon, broke his right foot while practicing in high jump shoes. Moore's track and field coach, Bill Bowerman, pointed this out to Moore and created a custom shoe in the six weeks it took for the fracture to heal.

He contacted the factory and instructed them on any changes that needed to be made, such as thickening the sole, widening the base, and combining uppers to fit various foot shapes. Moore then tried on the prototypes made by the factory. Bowerman then made further improvements and approvals based on the results. The shoe, later named the "Cortez," symbolizes Nike and Bowerman's commitment to "creating better products to improve athlete performance."

This event 52 years ago led to the creation of the Nike Classic Cortez KM QS, which is now being released. The shoe's pure white side features Moore's name, and the insole is printed with his former track and field training schedule. The shoe is available on the official website (https://www.nike.com) and at select Nike retailers.
