Nike scene experts stare at his shoes 25 players. This is called “Vapor Laser Talon” shoes, craft unique, traditional shoe Nike abandon the process, the use of 3D printing manufacturing, because it is possible to break out in a short time, to create a help athletes in the grass on the field. ” fly “up shoes.Almost all athletes are concerned about the foot of the shoes, it means lighter, more to the force. This Tony Bignell (Tony Bignell) fully understood, he was vice president (Nike) Nike footwear innovation, 17 years ago is a footwear designer. “Let the athletes run faster” is Bignell team is working hard to do. Nike designers for this frequent contact with athletes, expert advice and athletics coach,http://www.formfab.co.uk/, also Nike laboratory support. Michael Johnson (Michael Johnson) has swept the same Olympic Games men’s 200 meters and 400-meter race gold medals, one of Nike’s advice coach, he told Bignell asked: “Hey, you can make a pair of runs in the grass shoes, track shoes as fast as it do? “” he’s a big shot, but track and field. “Bignell told reporters, when Johnson made this suggestion, from rookie training camp just 7 months.In the usual shoe program designer must first listen to the needs of athletes, then design programs, etc. produced after test try to give athletes, if not achieve the desired effect, it means that all processes again. This process often makes people exhausted, Bignell said to produce a design concept entirely consistent with shoes, you may want to try on hundreds of times. “Design, modeling, do shoes, it takes a long time to go, but we have too little time.” Bignell recalls. Nike has thought of 3D printing technology in model design, and product design and development stage designer help speed a lot, Bignell said: “! OK, we try to make shoes with new technology it.”In the NFL rookie training camp and 40-yard dash is observed rookie scout explosive manner. For 40-yard dash, the start of the most critical first three steps. Shoes not only to generate grip push forward the athletes must also be just right to force.

Nike can bring a key factor in the proper place on the strength of the outsole of the shoe. High-speed camera, the Nike athlete running action decomposition observed traction, grip and a lot of analysis soles, looking relationship between performance and the sole, until the athletes said:. “Ah, this really makes me run faster.” the balance between friction and may fall found.
