New rules for running shoes - because of Nike
Vaporfly: What sounds like a superhero from Marvel is a running shoe from Nike. And it has recently caused quite a stir on the scene. Now there are new rules because of this marvellous shoe. The most important points.
At the end of January, the World Athletics Federation announced a rule change for competition shoes. This was in response to the controversy surrounding Nike's latest running shoe development. An internal World Athletics working group concluded "that there is independent research indicating that the new technology used in the soles of road running shoes offers a performance advantage."
World Athletics saw the level playing field at risk and reacted. The three most important rule changes that have been in force since 30 April:
- The sole of a running shoe may be a maximum of 40 millimetres thick.
- A new running shoe must have been available on the market for at least four months before it can be used in competition.
- Shoes may only have one plate in the sole. The plate may consist of several parts, but they must be in a row in one plane and must not overlap.
A rule change that changes nothing
It is obvious that World Athletics is reacting to the hype surrounding the Nike models "Vaporfly4%" and "Vaporfly Next%" and their influence on running times in marathon competitions. However, the new rules hardly change anything in this respect. With the exception of the prototype with which Eliud Kipchoge broke the 2-hour barrier for the first time at the Ineos 1:59 Challenge in Vienna in 2019, all previous Vaporfly models are still permitted under the new rules. World Athletics is thus aiming for future developments. In Vienna, Kipchoge ran in a shoe with a sole thickness of around 50 millimetres and several carbon plates. With the new regulation, both are no longer permitted.
