Amosan breaks world record in 100m hurdles to revive debate over super shoes | World Championships in Athletics

Nigeria’s Toby Amosan has reignited the controversy over new track and field shoes as she unexpectedly smashed the world record in the 100m hurdles in Eugene.

On the one night that Mundo Duplantis also broke his pole vault world record, Amosann clocked a staggering 12.12 seconds in the semi-final to beat her best Kendra Harrison by 0.08 seconds – breaking her personal best time by nearly three tenths of a second.

Immediately after the race, Michael Johnson, the former world record holder in the 200m and 400m, wondered if the timing system at Hayward Field had broken. It was far from the unit. However, it turns out that Amusan got a boost with Adidas Adizero Avanti shoes, which are designed for runners of 5km and 10km, instead of spikes.

After running faster to win gold in the final nearly two hours later, Amosan revealed that she accidentally stumbled upon the idea of ​​using the shoes, which have extra bouncy foam, after injuring her foot.

Adidas called the Adizero Avanti “like hitting fast forward” and pledged that the shoes “provide a fast, powerful ride with high traction and reduced fatigue, so you finish the 5k and 10k races with a kick.” There is nothing illegal in the shoes, as the current rules of world athletics state that soles of a sprint can not have soles thicker than 20 mm – like Adizero Avanti.

Until now, these shoes had always been used in long races, but the benefits for Amusan were obvious as they flew high over the barriers and in the record books. “My abilities are not centered around nails,” said the Nigerian, who ran 12.06 in the final, only to a wind speed of +2.5m/s to make it ineligible for standard purposes.

“I had patellar fasciitis early in the season, so that set me back a while,” Amosan added. “I spoke to adidas and asked if I could get the nails with a softer sole. They recommended a lot of things and I feel comfortable in them. [the shoes]So I basically used it all the time.”

The new breed of super boots appears to be especially helping to make it through, as Sydney McLaughlin also broke the women’s 400m hurdles record wearing the latest New Balance models earlier this week.

There was another world record at the conclusion of these tournaments where Duplantis achieved 6.21 metres. The Swede won another gold medal – and like Amosan, he left Eugene with an additional check of $100,000.

“I have to save the best for last,” said Duplantis, who beat his nearest rival Christopher Nielsen by 27 cm. “You get a lot of pressure on you when you’re the only person competing the entire track. It’s an honor for people to stay in their seats when it’s literally just me on the track. It was such a pleasure to jump there, honestly.”

When asked how he would celebrate, the Olympic and world champion smiled. “I’m probably going to stay up kind of late,” he said. “Maybe these shows kinda require something fun.”

Earlier in the day, Jacob Ingbrigtsen made up for his 1500m defeat to Jake Whiteman with a dominant performance in the 5000m. The race wasn’t fast enough to impair the Norwegian’s bottom speed, and he was able to take the lead with the 900m to go, gradually increasing his pace before heading home.

Such was his dominance that he was even able to celebrate by pointing his finger at the crowd and relieving before crossing the line. “I didn’t want to finish the sprint because I wanted to prove that I was the better guy,” said Ingebrigtsen, who beat Kenya’s Jacob Krupp for silver by 0.74 seconds. “It was a great race but I wanted and needed it. It was a really great feeling.”

Elsewhere, German Olympic champion Malaika Mihambo continued her dominance in the women’s long jump by climbing to a second consecutive world gold with a final jump of 7.12 metres.

Mihambo was on the verge of being knocked out of the competition after she missed her first and second jumps but recovered well to score a valid third attempt of 6.98m. Nigeria’s Ese Brume took the silver with 7.02 metres, while Brazil’s Leticia Oro Melo took the bronze with 6.89 metres, a personal best.

Then, World Athletics revealed the record-breaking number of countries won gold medals in a single tournament, with 29 countries taking turns taking the podium, compared to 26 in 2017. Peru, Kazakhstan and Nigeria won the first. all-time gold medals, while India and Burkina Faso enjoyed their best-ever medal performance in winning the silver medal.
