There's some crazy technology being used to make Nike's new boots. What sort you ask? How about 3D printers. They allowed Nike's designers to prototype and test new footwear designs with a remarkable quick turnaround.

The result is the Vapor HyperAgility Cleat, and it features re-engineered studs that Nike claims will give football players the grip to explode off the line. It will also give them the grip to stop and turn on a dime.



The Vapor HyperAgility cleat features an aggressive-looking tri-star stud design that Nike believes will give football players the speed they need for running down the field.

The studs are engineered to also serve as brakes as much as they provide extra traction for acceleration. The shoe's upper features Nike's woven Flywire cabling which is threaded through the cleat itself to help prevent slippage during a dash.

Is this an unfair technological advantage?[Nike]
