Wrong, no super shoe for Kiplimo's 26:33. His 7:26.64 3k and 12:48 5k from 2020 were also done in Mamba's. Dude is a huge talent. All sources below
"Kiplimo said his goal was only to run under 27:00. He ran in Nike Mamba spikes. I asked him why he didn't run in the new-age super-spikes like the Dragonfly: "It's not comfortable for me, but maybe in the Olympics I will use it. This mamba is comfortable for me.""
