Sports brand Nike has unveiled the first boots for American football players with 3D-printed studs (+ slideshow).
Nike's Vapor Laser Talon boots are fitted with a footplate made by selective laser sintering, a process that uses lasers to fuse small particles of material together.
With laser sintering, Nike's designers were able to prototype the boots much faster than usual and make updates as they went along. In future, boots could be individually shaped for each player.
The 3D-printed footplate also makes the boot extremely light, weighing in at 158 grams, and improves traction on the turf to help players run faster. According to the sportswear company, the boots can markedly improve a player's "40-yard dash" time – the standard measure used by scouts to assess speed and ability.
We've published lots of Nike shoes featuring the latest sports technology, including the spike pads worn by Paralympic sprinter Oscar Pistorius and football boots partly made from castor beans – see all Nike design.

Here's more information from Nike:
The quest for acceleration and speed has long been the north star for athletes across sport, and in order to excel in the game of football, the mastery of these skills is seen in the 40-yard dash. Played out on a national stage in Indianapolis, pro scouts clock 40-yard dash times in order to assess and translate these measurements to a football athlete’s game-time ability.
Today, Nike Football debuted the Nike Vapor Laser Talon with a revolutionary 3D printed plate that will help football athletes perform at their best. In a version built to master the 40, the Nike Vapor Laser Talon weighs a mere 5.6 oz. and is specifically designed to provide optimal traction on football turf and to help athletes maintain their “drive stance” longer.
With more than 40 years of athlete insights and innovation across sport, Nike designers worked with elite trainers within Nike SPARQ as well as long time partner and gold medal sprinter Michael Johnson to understand how he and his team at Michael Johnson Performance train football athletes for the 40. According to MJP Performance Director, Lance Walker, an athlete’s “Zero Step” is a pivotal point that can make or break an athlete’s 40 time. In the moments before that first step hits the turf, his propulsion and acceleration speed are determined. At that point, it’s all about geometry.
“Nike’s new 3D printed plate is contoured to allow football athletes to maintain their drive position longer and more efficiently, helping them accelerate faster through the critical first 10 yards of the 40,” said Johnson. “Translated to the game of football, mastering the Zero Step can mean the difference between a defensive lineman sacking the quarterback or getting blocked.”
The plate of the cleat is crafted using Selective Laser Sintering technology (SLS). It is the sport’s first 3D-printed plate. SLS is a manufacturing technique that uses high-powered lasers to fuse small particles of materials into a three-dimentional shape. Through proprietary material selection, Nike was able to prototype a fully functional plate and traction system within a fraction of the traditional timeframe and at a fraction of the weight. The SLS process allows for the engineering and creation of shapes not possible in traditional manufacturing processes. It also provides the ability to make design updates within hours instead of months to truly accelerate the innovation process to never seen speeds.
“SLS technology has revolutionized the way we design cleat plates – even beyond football – and gives Nike the ability to create solutions that were not possible within the constraints of traditional manufacturing processes,” said Shane Kohatsu, Director of Nike Footwear Innovation.
The way athletes train continues to evolve, and Nike continues to push the boundaries of innovation even further. By listening to the voice of the athlete, Nike is able to evolve footwear, apparel and equipment to help athletes achieve their highest potential.
