The Nimbus has a midsole made of FF Blast+, which provides a soft ride but lacks energy return, making it best suited for slow, relaxed runs where pace doesn't matter.

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 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 brain is the conductor of the orchestra, the muscles are the instruments. When your body is out of alignment, the orchestra is playing out of tune. Misalignment in the musculoskeletal system is frequently the root cause of chronic pain and the resulting poor posture.

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.

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.

The midsole of the Nimbus 28 is slightly softer than the 27 but it's not very noticeable. The 28 midsole is also more sculpted and more streamlined which is how they managed to reduce the weight. The 28 is 7% lighter than the 27.

Buying new ski boots is an exciting process, but it's one that can easily be done wrong. If you decide to go into the shop and just try on boots with little guidance, or to order boots online hoping they'll fit, there's a good chance you'll wind up with an improper fit. Boot Solutions explained why buying boots without expert advice can lead to disaster.

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.

Rather than waiting until you arrive in a ski village or going out of your way to drive into the mountains, Boot Solutions is introducing a process in which you simply scan your feet and they do all the fitting remotely. Overall it seems pretty simple. You use the Boot Solutions app on on your phone to take a medical grade 3D scan of both feet and the company offers you plans from there.

Bracesys sidesteps all these limitations with an adjustable framework of segmented units, articulating connectors, and tension dials. The entire system weighs just 150 grams and folds flat into an envelope, yet provides rigid support comparable to traditional casts. More remarkably, clinicians can customize it to each patient's anatomy in real time, adjusting the fit as swelling decreases and healing progresses.

The Swiss brand's new LightSpray Cloudmonster 3 Hyper doesn't have a traditional upper. Instead, a robotic arm sprays a single continuous filament onto a foot-shaped mold, and in about three minutes, the entire upper is formed. No seams. No laces. No glue. The result bonds directly to the midsole through thermal fusing, and the whole shoe is made from just eight components.

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.

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.

That's why we chose the Tempur-Pedic "ProAdapt" Mattress as our top overall pick-the support layers feature high-density foam on top of steel coils that not only help with lumbar support but also minimize motion transfer, so you sleep soundly even if your partner can't stay still.

In addition to being comfortable to wear for long periods of time, I make sure my sneakers are supportive, don't give me blisters, and have a long-lasting quality. Skechers Hotshot Cool Transition Suede Sneakers from QVC met all of these requirements with flying colors after I tested them out recently, and they have become my go-to pair of walking shoes.

If you've shied away from buying leather sneakers for trips out of a fear that they might cause blisters, give this low-top option from Quince a try. Not only are they "super comfortable right out of the box," according to customers, but the sneakers' soft cotton lining and padded interior are ideal for "all-day comfort."

After reading through Oprah's Favorite Things List this year and purchasing this incredibly soft set that I now wear at least twice a week, I now know I can trust anything Oprah recommends. This includes Vionic, the shoe brand known for its comfortable, stylish footwear. Oprah isn't the only one who swears by them, either-podiatrists regularly recommend Vionic styles for their supportive design, all-day cushion, and foot-healthy construction.

The Brooks Adrenaline GTS reaches a major milestone in 2025 with the release of its 25th edition. Outside of the ASICS Kayano, it's hard to think of another stability trainer that has remained in production for this long. That longevity speaks to a shoe built on a strong foundation, one that has continued to evolve over the years while maintaining its place as one of the best-selling stability shoes on the market.

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.
