Lately all kinds of people try to tell us the Kipchoge’s shoes shouldn’t be legal because they propel him like a trampoline. So here are some fact:
1. If it were the shoes all runners without exception who were them would significantly improve, and this isn’t the case.
2. Kipchoge ran London 16 without these shoes and clocked 2:03:05. Then he ran London 19 WITH the shoes in similar conditions and clocked 2:02:38. That’s not even 0.5%! And I can give many more examples like this.
I even have a feeling that he could have gone faster with “normal” shoes and not these moon boots. So it isn’t shoes! Might be EPO, but not shoes.
The shoes is plainly marketing gimmick to make amateur runners spend 250-300$ on shoes
