Getting shoes that work with your foot design rather than against it is a very good and necessary first step. A really great insole can help give much-needed support and stability.

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.

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.

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 gravel edition sticks with the same PEBA and EVA hybrid midsole with a transition-smoothing curved rocker, but adds extra grip in the form of a 2.5-mm lugged outsole. There's also some extra reinforcement around the toe box.

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.

Puma PUMA MagMax Nitro 2 Verdict The PUMA MagMax 2 is a good max-stack daily trainer with deep cushioning and a moderately bouncy ride. Version 2 gets rid of the annoying poking arch and has a tweaked midsole that's more energetic. I was impressed with the updates made to the MagMax 2; however, there are similarly priced competitors with even more energetic rides. Daily training

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 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.

The Hyperion Elite 5 has a midsole made entirely of DNA Gold, a PEBA foam. It's the foam with the highest level of energy return of all the Brooks midsole foams. The Hyperion Max 3 has a dual-density midsole with a top layer of DNA Gold and a bottom layer of DNA Flash, an EVA foam. The firmer DNA Flash provides a stable, durable base. Both shoes have plates in their midsoles but the Hyperion Elite 5 has a stiff carbon plate while the Hyperion Max 3 has a flexible nylon plate.

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.

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.
