A “super shoes” war is taking place in the marathon world record march.

In the past month, the men’s and women’s world records have changed one after another at the marathon. On the 24th of last month (Korea Standard Time), Tigist Asefa (Ethiopia) completed 42.195km in the women’s division of the 2023 Berlin Marathon in 2:11:53, shortening the previous world record of 2:14:04 set by Brigid Kosgei (Kenya) at the 2019 Chicago Marathon by 2 minutes and 11 seconds. And on the 8th, Kelvin Kiptum (Kenya) finished the full course at 2:00:35 at the men’s 2023 Chicago Marathon in Chicago, Illinois, advancing the world record of 2:01:09 set by Eliud Kipchoge (Kenya) at the 2022 Berlin Marathon by 34 seconds. 스포츠토토

However, it is not Asefa and Kiptum that are drawing attention, but the sneakers they wear. This is because Asepa and Kiptum ran in shoes that are not currently released. Adidas’ Adizero Adios Pro Evo 1, which will be released this month, and Kiptum have worn a prototype of Nike’s Alpha Fly 3 (tentative name) to be released next year. Siphan Hasan of the Netherlands, who wore the same AlphaFly 3 prototype as Kiptum, won the Chicago Marathon women’s race with a time of 2:13:44. The Adizero Adios Pro Evo 1 costs 599,000 won. The price of AlphaFly 3 is undecided, and the previous model, AlphaFly 2, is 329,000 won.

The two sneakers focused on weight reduction and even maximized the repulsion by inserting carbon plates (carbon fiberboard) into midsole (medium window). In 2019, Kipchoge wore the first prototype of AlphaFly 1, the beginning of these sneakers, and ran 42.195km in 1 hour, 49 minutes and 40 seconds. It was not recognized as an official record because it was not an official competition, but it sparked controversy over “technical doping,” and eventually the World Athletics Federation announced regulations on sneakers.
