Brittany Antoinette Wilson's dad has been a collector for over 30 years, starting with comics and expanding to baseball caps and sneakers. His sneaker collection, now around 500 pairs, reflects his passion for fashion and appearance.
Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.
The system, tested in prototype form by NPR at the company's headquarters, consists of fairly standard-looking sneakers with a carbon fiber plate running through the soles. These sneakers are attached at the back to close-fitting, 3D-printed titanium leg shells that cinch to the calves. The battery-powered contraptions, containing complex motors, sensors and circuitry, weigh a couple of pounds and look like something out of Terminator or RoboCop.
We were not expecting to find so much richness and depth from a physics point of view underneath the sole of a shoe, says Adel Djellouli, a scientist at Harvard University and co-lead of the study. In a new study, scientists explore the physics that give rise to the familiar squeak of basketball shoes sliding on a hard surface.
New Balance has turned its "dad shoe" image into a driver of growth. According to a recent CNBC report, New Balance sales were up 19% to $9.2 billion in 2025. The sneaker giant grabbed market share from rivals like Nike, per the report. New Balance told CNBC that it could reach its target of $10 billion in annual revenue by the end of 2026.
Patel's bespoke shoes were black, white, and yellow, and featured a number 9 on the side to signify that he is the bureau's ninth director. A "K$H" logo on the tongue is Patel's personal logo (FBI directors have personal logos now), and a skull from the Marvel character Punisher appeared across the back of the shoe, along with the FBI's slogan "Fidelity, Bravery, Integrity."
Specifically, the company is focusing on the production of its newest, weirdest shoe-a giant soled laceless running shoe with a single-piece toe box made of "hyper-foam" plastics sprayed on by robot arms. The plastics are 40 percent biofoam, and the shoe is made of just eight pieces; On says its minimalist approach saves on the shoe's carbon footprint.
I had to blink the first time I landed on the product page for the Nike ACG Ultrafly Trail. I'd seen lots of promotional assets ahead of the release (see here and here), where the trainer is caked with mud. But in the end, it's hi-vis orange - and like any other brand-new shoe, being sold without a stain or scratch.
In the show, "dirty" extends to anything that breaks fashion's pact with propriety. Here are clothes caked in grime, blotted with makeup, stiffened by salt, pieced from trash, frayed, and faded. The garments span decades, from the 1980s through the mid-2000s, when the likes of Vivienne Westwood and Jean Paul Gaultier built their fame on defying convention, to today, when corporatization has made such daring increasingly rare. But forgoing practicality frees certain designers from the demands that the body be polite-and thereby policed.
