The IAAF restricts shoe technology and prohibits AlphaFly
For months that an official pronunciation was being cooked by the International Athletics Federation (IAAF) about technology in competition shoes, something that had taken a good part of the current athletic events, especially after the INEOS Challenge 1:59 that Eliud Kipchoge achieved with a Nike prototype (the famous AlphaFly) that surprised locals and strangers and about which virtually nothing is known (beyond ensuring that, among other things, things have up to three plates carbon fiber).
The prototypes are over
"As of April 30, 2020, any shoe must be for sale and available in the market (either online or in store) for any athlete and for a period of at least four months before it can be used in competition, ”explains the federation in a statement. In this way, it makes clear that cases such as the AlphaFly of the world marathon record holder or the Adidas that wore athletes such as Kiplimo and Kipchumba in the Houston Media will be banned and any athlete running with them will be automatically disqualified.
In addition to prohibiting prototypes, the federation regulates the height of the sole (not exceeding 40mm) or the number of carbon plates inserted They can have. Thus, and according to AFP, the model used by Kosgei (with which he sprayed the previous record of Paula Radcliffe) can be used in the Tokyo Games. For competition nail sneakers, an additional plate is allowed but only in order to attach the nails to the sole.
World Athletics modifies rules governing competition shoes for elite athletes.
