A four percent gain in efficiency might not mean much on a jog around the neighborhood, but when you're running a marathon, it means a lot. The Nike Zoom Vaporfly 4% promises that exact improvement over their previous fastest marathon shoe. Born from the company's Breaking2 project — an effort to break the two-hour marathon barrier — they have a full-length carbon fiber plate that minimizes energy loss, a ZoomX midsole for cushioning and bounce, and a Flymesh upper to provide support without constraint. The result is the fastest shoe Nike's ever made for distance runners, and, perhaps, the first to cross the finish line in under 120 minutes.
The company's named after the Greek goddess of victory. The Nike Goddess Flyknit Racer promises to get you across the finish line in style. Like other Racers, it has a Zoom Air unit in the forefoot for cushioning, a full-length Phylon midsole for added comfort, and a lightweight Flyknit upper for a lock-down fit. But unlike other styles, this one comes in an all-white colorway — with a barely visible Swoosh — that looks as good with jeans as it does on the track.
They're not a remake of a classic silhouette. They just look like it. Drawing on '70s running shoe design, the Adidas Iniki Runner offers old-school simplicity with all-day comfort. The upper, a mix of two-way stretch mesh and suede, hides an OrthoLite sock liner, while the shiny tongue and serrated 3-stripes add visual interest. An exposed Boost midsole provides much-appreciated cushioning and bounce, while the gum rubber outsole ties the design together as a single, fashionable whole.
Chuck Taylors are acceptable footwear for a variety of occasions. The Converse Chuck Taylor All Star Modern Lux only expands their versatility. A monochromatic treatment gives the classic silhouette an added touch of restraint, with a supple leather upper, embossed patch, and full-length, color-matching Phylon outsole for comfort. Available in white or black.
As flying cars and Hoverboards have shown, it's not easy to bring the technologies found in Back to the Future Part II to life. This Nike Hyperadapt Teardown takes a look at how the auto-lacing system from the film was recreated. Hidden inside the shoe are sensors to let it know when you've it put on and buttons to let you adjust the fit. Heavy duty motors attached to Flywire pull the laces tight, arrays of LEDs provide lighting effects, wireless charging eliminates the need for battery changes, and an ARM Cortex M4 processor runs the show. It's like having a motor-laden smartphone hidden inside each shoe.
