It was the shoe what won it.
Just to be clear, the following copy is taken from a BBC Sport news story, not an Adidas press release:
What shoe did Sawe, Kejelcha and Assefa wear? All three athletes wore Adidas' Adizero Adios Pro Evo 3. The shoe was launched on 25 April, just two days before the world's best took to the streets of London.
It is the third iteration of a hugely popular shoe. Adidas worked with Sawe, Kejelcha and Assefa over the last three years to produce this version of the trainer.
