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.
