From August 4 to 13, 2017, the International Association of Athletics Federations kicked off their 105th year by showcasing some of the best marathoners in the world during their event held in London.

Our eagle-eyed friends over at Canadian Running Magazine were able to determine who was running with what running shoes.

Here’s what the top runners in their marathon wore on their feet, with Nike and adidas being the two top brands shown off. It’s important to note, though, that Eliud Kipchoge and Mary Keitany were among those marathoners who weren’t able to compete in London this year.

And without further ado, check out what world-class runners have on their feet during the event.
