The new store preserves the building's historic character-keeping original brick walls exposed-while layering in contemporary materials such as metallic finishes, reflective surfaces, and semi‑gloss flooring.

The supportive high drop Cloudnova 2s are down from $170 to $115, making them an excellent choice for serious runners looking for quality at a discount.

For most of human history, night arrived as a planetary certainty. Darkness spread across landscapes, and the sky revealed thousands of stars. Today, that sky is disappearing. Artificial light spills upward from cities, scattering through the atmosphere and turning night into a permanent haze. Research mapping global sky brightness shows that more than 80 percent of humanity now lives under light-polluted skies, and the Milky Way has vanished from view for over a third of the world's population.

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."

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 Eski.Sub draws inspiration from the visual language of Brutalist architecture and the cultural atmosphere of UK grime music scene. The project examines the relationship between design, urban context, and emotional listening experiences, positioning the loudspeaker as both an audio device and a spatial object.

The results showed that the squeaking sound is produced by wave-like patterns across the rubber surface, contacting and then releasing from the glass, allowing the sliding between the surfaces. The waves move across the interface between the two materials at a speed of nearly 300 kilometers per hour.

The ring-like portable speaker has a lanyard that lets users hook it onto a backpack or simply carry it around the wrist. Another option is to wear it around the neck, turning the device into a personal stereo system that surrounds the user with sound while remaining lightweight and portable.

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.

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.

I remember standing in a boutique in San Francisco, sliding my credit card across the counter for a pair of $400 sneakers I absolutely could not afford. My second startup had just folded-eighteen months of burning through investor money, eighteen months of watching something I built crumble in slow motion-and I was drowning in debt. But there I was, walking out with a shopping bag and a receipt that made my stomach turn, telling myself this was an investment in how people perceived me.

While we started designing a retail space for the brand, we perceived Gully Labs as a celebration of Indian street culture, glorified, unified, and expressed through sneakers and apparel that pay homage to Indian craftsmanship and the raw vibrancy of the streets. Every element, from design to detailing, reflects this authenticity, positioning the brand not just as a retail destination but as a cultural movement.

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.

They're called open earbuds (or open-ear buds, depending on the brand), and just about every audio brand has a pair (or three). They come in a slew of styles, but most either loop around your ears like older Beats buds, or clip on like funky-futuristic earrings. Whatever the style, they're designed to deliver satisfying sound while keeping your ear canals open to the sounds of the world around you.

The writing was always on the wall -- from the moment the London-based tech company debuted with a pair of earbuds with a transparent design. Yet, somehow, I found myself taking a step back when I unboxed the . To an extent, Headphone 1 represent the pinnacle of Nothing: a playful, finely tuned pair of headphones with Teenage Engineering influence, a seamless software experience that leaves no iOS or Android user behind, and a feel and finish that could split any room into two.

For years, innovation in earbuds centered on sound quality, battery life, and noise cancellation, while aesthetics converged on a single in-ear silhouette. Today, designers and brands are challenging that orthodoxy, reimagining earbuds as jewelry-adjacent objects that sit visibly on the ear, more ear cuff than invisible tech. The idea of elevating earbuds into luxury objects is not new. Over the past decade, bespoke jewelers have produced gold-plated AirPods, diamond-encrusted headphones, and one-off couture audio pieces intended as collector's items or status symbols.

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.

I was able to take the Sidekick for a spin around the CES showfloor and it was a truly surprising sensation. The best way I can describe walking with the Sidekick powered on is that with every step forward there's a noticeable upward push from under your heel. It wasn't enough to throw me off balance, but it did feel a bit strange.

At the end of the day, choosing your pair of Hokas will come down to personal preference. Think about your intended use and issues you have faced previously in walking shoes. If you're looking for a pair for walking that have more cushion than others, you will want to look for those that have the maximum cushion and stability. Or if you want a lightweight pair that you can also use for running, consider weight and versatility.

Stylists say Mary Janes and ballet sneakers will be trendy as they prioritize comfort and style.
