Über-Adaptable Airless Tires

By Lisa Eadicicco

In the future, our cars will be smart, and our tires will be smarter. For starters, it’s airless, eliminating the need to worry about pounds per square inch. It’s also made from recycled materials in an effort to reduce waste. But the most impressive feature may be its 3-D--printed treads, which can be swapped in and out to accommodate various road conditions—without changing the tire itself. The challenge will be figuring out a way to do it quickly, says Terry Gettys, who helped lead the project, “because consumers are going to want their tires [ready to go] in just a few minutes.”

A Shoe Engineered to Boost Performance

By Julia Zorthian

Imagine a shoe that lets you run faster, pivot better and jump higher. That’s the idea behind the Futurecraft 4D, a new sneaker whose midsole can be expertly tailored to the needs of its wearers—not only in size and shape, but also in flexibility, impact type, cushioning and more. The key is the 3-D printing process, which enables the company to “look at every single square millimeter of a midsole and tune it from a performance standpoint,” says Al VanNoy, who headed the project. It would take weeks to make those modifications using traditional shoemaking methods. But the Futurecraft 4D midsoles can be printed in as little as two hours, meaning they could even be produced in stores. At least that’s a possibility for the future.
