Nike announced the update to its fastest running shoe back in late August — a simple Flyknit upper to keep things fresh and fast. The shoes are finally available, but already only in limited sizes. This unisex shoe flies off the shelves every time it’s restocked and for good reason. Elite marathoners like Eliud Kipchoge, Galen Rupp and Shalane Flanagan have all rocked the shoe and seen incredible times. Most recently, Kipchoge ran a new world record at the Berlin Marathon — a 2:01:39.
Data has shown that the sneakers can make you up to four percent faster, which is a big chunk of time when you look at a distance like a marathon. The New York Times even verified some of Nike’s claims, making the shoe even harder to find. The new Flyknit version of the shoes is lighter and more breathable than the original — and the velocity-inducing carbon plate is still underfoot. While $250 is a steep price for a pair of sneakers you should only wear on race day, the data tells a story that has people running to find them.
