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.
This is an absolute beginners course on the foundations of classical ballet and, a single catastrophic line dance lesson aside, it is also the first dance class I have ever attended. I am in the minority. As we take the barre, it quickly becomes apparent that not being able to tell my left from my right will be a significant deficit over the next 16 weeks. This, however, is a tertiary concern.
But instead, they find their way to a small studio, where they join 27 others in strapping on a pair of high heels and throwing themselves into two hours of dance moves. This is the beginners heels class at Vibe Dance Studio, which was started by Izzy Gonzales and her dad Ed four years ago. It's a place where people can show up exhausted, but end up with so much energy they don't want to go home.
There are certain suitcase staples worth having in your travel wardrobe. An effortless pair of wrinkle-free travel pants is one of them. A comfy pair of shoes is the other. While clogs and flats make a stylish choice, sneakers are our top travel shoe pick, especially when they're known to endure 13-hours on your feet or 15,000 steps without blisters, like two of our editors' favorite Adidas styles.
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.
Squeaking occurs across various contexts including shoes, bike brakes, rubber tires, and biomedical implants when soft and hard surfaces contact each other. Researchers used high-speed photography to study a rubber block sliding across hard acrylic to identify the source of these sounds. The investigation revealed that pulses similar to earthquake dynamics drive the squeaking phenomenon.
Now, returning in 2.0 trim, it's been treated to a New York-inspired update thanks to the folks at HSDT. Proportions and comfort have been elevated, while the sneakers' visual language has taken shape through features inspired by NYC's everyday structures. This continues the brand's "The Architecture of Everyday Life" ideology, focusing on scaffolding and steel beams, stairwells and sidewalks, mesh fences, utility grates and metals.
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.
The On Cloudlfow 5 is a versatile daily trainer that is heavily focused on fast training runs, intervals, and speed workouts. They are part of On's lineup of performance-oriented footwear;they are not just an "everyday" sneaker. It is packed with numerous great technologies from On. Some of the new features include a top layer of Helion HF supercritical foam, a nylon-blended Speedboard, a rockered midsole geometry, and an upper made from engineered mesh.
There is every chance that 2026 will be the year you see your first pair of Gardana gardening clogs in the wild. In fact, if you spend much time on TikTok, or live in Brooklyn, you've probably already been seeing them for months, if not years. I saw my first pair a few weeks ago. I watched a dad dropping his kids off at school in head-to-toe Carhartt, a pair of Gardanas peeping out from below his trousers like a shy frog.
The earliest jewellery ever discovered wasn't gold or gemstone at all, but fish bones. In prehistoric times, hunters wore bones, teeth and claws from their kills as talismans of luck and prowess. For Italian shoe maestro Giuseppe Zanotti - famous for his sculptural, jewel-encrusted heels - this idea of turning humble scraps into ornamentation has long been second nature; during a seaside dinner in 2004, Zanotti sketched a fish skeleton on a tablecloth.
Paris is a city designed for strolling, with its grand boulevards, photogenic buildings, and hundreds of beautifully manicured parks. My biggest mistake on my first trip to Paris? I packed the wrong footwear. I visited in late May and brought an overstuffed suitcase of strappy sandals and heels. After a day of rain (leading to chafing and blisters), I popped into a few shops in the Marais and purchased comfortable sneakers and ankle boots that I wore on repeat for the rest of the trip.
