Kiptum’s time beat that of previous record holder Eliud Kipchoge, who held the men’s world record with a time of 2 hours, 1 minute and 9 seconds, according to ESPN. As previously reported in Footwear News, this is the latest running record to be broken in 2023, following Tigst Assefa’s record-setting win of 2 hours, 11 minutes and 53 seconds at the women’s world marathon in September.

Nike first released its Air Zoom Alphafly sneaker in 2020. As previously reported in FN, the line has expanded with a range of styles — including the Air Zoom Alphafly Next 2% sneakers, which were made with input from Nike runners including Kipchoge.

Nike’s Alphlafly sneakers have grown rapidly popular in the running field. In the past, the line’s been worn by athletes including Kipchoge — who wore an Alphafly prototype in 2019 when he recorded an unofficial sub-two-hour marathon for the Ineos 1:59 Challenge. In 2022, Kipchoge also wore the Nike Air Zoom Alphafly Next% 2 running shoes while breaking his own record at the Berlin Marathon, which stood until today.

Nike’s Alphafly sneaker range is renowned for being lightweight and balanced, thanks to features like knit Flyknit uppers and notched laces. The shoes also feature Nike’s signature ZoomX foam within their thick soles, creating a comfortable base with added cushioning. Carbon fiber plates enhance these styles with high energy return as well, making the shoe both easy to wear and efficient for racing.
