BEST FOR SPEEDWORK- Nike Zoom Fly 4 Premium One downside: ItвЂ™s heavier than the regular Alphafly. According to Nike, the shoe is made of at least 50 percent recycled content by weight. In late 2021, Nike also released the Alphafly Next Nature, a new version that utilizes scrap materials, including leftover ZoomX foam, in the upper and sockliner. What does all that tech do? For Kipchoge, at least, it enables record-breaking speed. With this shoe, Nike threw in everything but the kitchen sink: two Zoom Air units in the forefoot, even more ZoomX foam in the heel, a full-length carbon fiber plate that varies in thickness depending on shoe size, and a new ultralight upper material called AtomKnit. The latest in NikeвЂ™s quest to build the fastest shoes on earth, the Alphafly is the production version of what Eliud Kipchoge wore when he broke the two-hour marathon record in Vienna in 2019. This technology continues in the Air Zoom shoes of today. It debuted on the Air Tailwind shoe in 1978, but Nike continued to refine the design and released Zoom Air cushioning in 1995. Another notable Nike invention of this era was the Air Sole design, which featured an air-filled bag in the midsole to absorb shock.

Designed to be lighter and more water-resistant than other sneakers, the Cortez gained a following for its full-length cushioned EVA midsole, a new feature that gave runners unprecedented comfort. In 1972, Knight and Bowerman released the Cortez, one of NikeвЂ™s most iconic shoes.

Now a global behemoth, Nike maintains its strong commitment to creating shoes that help runners go faster and farther. The pair began experimenting with new running shoe designs, and that itch to push the envelope has been a Nike hallmark ever since. Phil Knight started Blue Ribbon Sports in 1962 to sell Onitsuka (later known as Asics) shoes in the U.S., and by 1964 his former coach Bill Bowerman had joined him. The company that would become one of the biggest names in sports all began with a University of Oregon runner selling imported shoes from the back of his car.
