Why are Nike sneakers banned?

Running shoes banned in marathon are Nike's "magic shoes". The Times reported that Nike's Zoom Vaporfly NEXT% running shoes will be banned by the IAAF.

The reason is that IAAF thinks that the design of NEXT% running shoes does not meet the relevant requirements, such as the thick soles and the use of carbon plates, which makes Nike running shoes lose the fairness of marathon. Athletes can't wear this kind of shoes in the future, but the record set by wearing this kind of shoes before will not be affected.

Nike shoes are stimulants for marathon runners.

Of course, the scientific and technological elements in Nike running shoes can't obviously improve athletes' ability and won't harm athletes' health, but its role in improving sports performance is quite obvious. So some top marathoners think that NEXT% running shoes are like "stimulants" for marathoners.

In the Chicago Marathon on June 3, 20 19, 10, Kenyan female athlete Brigid Keji broke the women's marathon world record in 2 hours 16 and won the championship in 2 hours 14 minutes and 04 seconds. Koji also participated in the NEXT% running shoes competition.

Keji's performance is faster than the previous world record of 2 hours 15 minutes and 25 seconds 1 minute 2 1 second, which was set by Paula Radcliffe of Britain in the 2003 London Marathon. In addition, the world records of 20 19 for 5000m,10000m and half marathon were also broken one after another this year, and all the competitors who broke the records were wearing NEXT% running shoes.
