Designers of sports brands are racking their brains over how to make sneakers even more stable to run in them was easy and safe.
Their colleague Aarisha Netarwala has other worries: he makes sneakers that fall under their feet like dry sand. A young designer, a graduate of the College of Art and Design in Pasadena, Aarish Netarwala, has developed for Adidas running shoes that are heavier than any other footwear (except perhaps high-heeled shoes or heavy boots of career workers, but it’s not about this).
The footwear printed on the 3D printer consists of several dozen layers of material that support the foot at the right moments, and when the pressure on a particular area is small, they collapse. So the sneakers mimic running along the sand, which also keeps your weight only at the maximum pressure point, and falls off where less force is applied to it.
Prototype of “sandy” sneakers Netharwala made by hand, building up layers of granular materials, such as magnetic sand, on the soles of their own shoes; then the designer tried to run around in what happened. To achieve that it was hard to run, it turned out almost immediately, but with the stabilization of the foot there were problems; in the first prototypes with heavy and high soles the runner did not need to turn his foot. To properly distribute the weight, Netarwala began to print additional layers on the 3D printer, controlling the amount and density of the material in different parts of the sole. The designer added more to the heel and added a wrinkled structure under the middle of the foot, easing the rest of the boot.
Then Netarwala printed from the elastic thermoplastic layered structure of the entire shoe; Inside he placed a textile “sock”. In the end, the designer added the last chip – the ability to adapt the structure of the laminated frame to the individual features of the runner. Netarvala proposes to strengthen those parts of the structure that have the greatest load, and this depends on which part of the foot is landing and what the athlete is pushing.
Running on the sand has to put more effort than on the hard surface, so running on the beaches is popular among those who have few ordinary roads. Professional athletes run through the sand in the hill; for this they have to go to places where such dunes, natural or artificial, are. If the development of Netarvala is adapted for mass production, fans of hardcore races can not go anywhere; In the sand under their feet will turn ordinary asphalt.
