While it was rumored that the prototype that Kipchoge was carrying had three carbon plates, Bignell told Runner’s World that this was not correct. According to Nike, the three “critical” components of the Alphafly NEXT% are the full-length carbon plate, the Zoom X cushioning and the two Nike Zoom Air pods added to the forefoot to ensure responsive cushioning and responsiveness. These are all updates from the predecessor of the shoes and sneakers.
When Bignell spoke about Kipchoges Alphafly, he told Runner’s World that it would have been legal under the new WA regulations. The 40 mm stack height control is based on a men’s size of 8.5, Kipchoge runs in a 10.5.
Nike has confirmed that the shoe will be available on February 29, just in time for the United States Olympics. According to the new World Athletics regulations, a shoe must be on the market four months before it can be worn in competition. The shoe costs $ 300, which is about $ 231 at the time of writing.
In addition to Alphafly NEXT%, Nike will release updated training shoes based on the technology used in Alphafly. This includes the Nike Air Zoom Tempo NEXT%, which is designed for higher mileage and more frequent use. It doesn’t have a carbon plate, but it does have the Nike Zoom Air Pods in the forefoot. The pace is not allowed for the competition because the stack height is higher than 40 mm.
They will also launch the Nike Air Zoom Viperfly – their new running shoe. According to Kacamata Rayban, the shoe was developed for the 100-meter race and has a carbon fiber plate. It was developed together with the NEXT% to help the runners in the last 20 meters of their race. The Viperfly has a new Atomknit upper, a new version of Nike Flyknit.
