Athlete Eliud Kipchoge will be wearing the a pair of Nike trainers with 3D-printed uppers when he competes in the London Marathon this weekend.Nike revealed the shoes, which they claim are the first running shoes in the world to have 3D-printed uppers, earlier this week at an event in London.The uppers – the  top part of the trainer normally made from fabric – are made form a material dubbed Flyprint, which is constructed Nike Air Max 90 Homme using a  process known as solid  deposit modelling. Through this, plastic filament is unwound Nike Air VaporMax Mujer from a coil, melted and laid down in layers to form the shoe's shape.While Adidas unveiled its 3D-printed offering in 2016, Nike claims this is the first time in the world that an upper has utilised this technology.The shoe is the result of a year-long collaborative project with athlete Eliud Kipchoge – one of the runners who attempted to break the sub-two-hour marathon time wearing Nike's specially developed Zoom Vaporfly Elite trainers.Kipchoge ended up missing out by only 25 seconds, and Nike decided to work alongside Nike Air Max 2017 Womens him to improve the trainer for this year's event.His main feedback was that the shoe's upper absorbed water, making his trainers heavier as he made his way around the course. Apart from that, he noted that the shoe was "Nike Air Max Tavas Mujer perfect", so  Nike set about experimenting  with a 3D-upper they had been working on for over 10 years.

"Designers kicked off a rapid-fire prototyping phase, where they went through thousands Nike Air Max 90 Mens of upper possibilities before hitting print on several variations for each prototype."They went forward with so-called version D, but Kipchoge said the knitted upper still had its issues.In response, the designers quickly Nike Air Vapormax Womens made changes and sent the new shoes in a matter of days. Kipchoge tested and approved these, before suggesting he wore them for the London Marathon taking place this Sunday, 22 April 2018.The design process for the shoes begins with data taken from the athletes, including their running gait and foot's form.This data is then put into software to create the correct composition of the material, so the printer knows where  to layer Adidas NMD FemmeNike Air Presto Womens up and where to  create a tighter weave.Not only does this mean a tailor-made shoe, but Nike notes that through printing, it can prototype shoes "16 times quicker than in any previous manufacturing method"."One interesting benefit of 3D textiles over traditional 2D-fabrics is the increased dynamism made possible by adding an interconnection beyond a warp and weft; an advantage of www.daviddenardi.fr Flyprint textiles comes in the fused nature of the material," Nike said.

"Whereas in a knit or woven textile there is frictional resistance between the interlaced – warp and weft – yarns, in a printed textile, due to its fused intersections, there is greater potential for precision-tuned containment," the brand continued.Nike, which ranked at number 37 on Dezeen Hot List, often works alongside  athletes when innovating new shoes. The company previously  produced Nike Air Max 90 Femme Noir a custom Zoom Adidas Superstar Womens Superfly Elite shoe for Nike Air Presto Womens Jamaican sprinter Shelly-Ann Fraser-Pryce for the Rio Olympics, and it also scored goals for football, with a Magista boot that's said to allow players to better feel the ball.Nike's research laboratory has developed a vest to cool an athlete's body in less than five minutes, which tennis player Rafael Nadal has used in practice sessions during this year's US Open.
