World Athletics will enforce a 20mm sole limit for track shoes from Nov 1, 2024, aiming for fairness but sparking debate over its impact on performance.
World Athletics has earlier announced that athletes should wear shoes with a uniform 20-millimeter sole thickness limit for all events. This rule will come into action on November 1st, 2024, marking a notable change in the actions of the athletes.
This rule has been induced to welcome fairness in the game. However, this has sparked controversies. While many athletes have accepted it, some are still in dilemmas about the rule.
Well, let's look at how the rule will impact the performance. However, for now, let's look at the present thickness.
Current Shoe Sole Thickness Rules in Athletics
Presently, there is no such uniformity of sole thickness. Thickness normally varies according to the events in which the athletes participate.
Suppose, in events where an athlete will have run more than 800 meters, shoes are allowed to have a sole up to 25 mm. However, when it comes to shorter distances, the maximum thickness has been limited to 20 mm.
For field events, including the high jump, athletes have a 20mm limit. But for the triple jump, athletes are allowed to wear shoes with soles up to 25mm.
These rules were implemented in January 2022, based on the technological advancements in shoes. However, from 1st November this year, there will be no distinction in sole thickness in different events.
Point to be noted: the rules for road events like marathons and race walks, which permit a 40mm sole thickness, will remain unchanged.
Why is World Athletics enforcing a 20mm sole limit?
The main motto of World Athletics is to ensure fairness. As a result of this, the federation has decided to apply the rule of a uniform 20mm limit to the sole.
In recent years, advances in shoe technology—particularly with thicker soles and carbon fiber plates—have sparked debates about whether these shoes offer athletes some unfair advantage.
Thus, World Athletics created its own Working Group on Athletic Shoes in 2020. The main task of this group is to analyze the impact of shoe technology on performance. They also draft regulations, ensuring that athletes are focusing more on skills and not technology.
The new rule was announced well in advance to give shoe manufacturers ample time to adapt their designs.
Athletes' Reactions to the 20mm Rule Change

Top athletes have had mixed reactions to the upcoming rule. Joshua Cheptegei, the Olympic and World Champion in the 10,000 meters, supports the change, describing it as "for the benefit of the sport."
He added that the thinner soles won’t necessarily lead to slower times, emphasizing that performance is often influenced by an athlete's mindset. Cheptegei also noted that recent shoe technology has aided recovery between training sessions, which could be impacted by the new regulations.
Meanwhile, Muktar Edris, a former two-time 5,000m World Champion, said that a thicker sole helps the athletes, providing them extra "energy" and "push." A reduced sole may hamper a regular action.
The Controversy Surrounding Shoe Technology

The controversy regarding shoe technology is nothing new. Before 2022, the track spikes had soles with thicknesses up to 30 mm.
During the Tokyo Olympics, legendary sprinter Usain Bolt brought this issue to the public, citing the unfair advantage an athlete may receive due to thicker boots. Not only that, but with the increased use of technologically advanced shoes, world records that looked unbreakable are at stake.
Karsten Warholm, the one who holds the World Record in 400m hurdles, also expressed his concern. After winning the gold medal in the Tokyo Olympics, he questioned the boots of the runner-up, Rai Benjamin.
Warholm made serious claims that Benjamin used thicker Nike soles that provided the later an unfair advantage. Warholm's remarks not only concerned the federation but drew attention to the fine line between technological innovation and "technological doping."
The Impact of Shoe Technology on Performance

Eliud Kipchoge, the first athlete who broke the two-hour marathon barrier in 2019, sparked controversies at his time as well. He used the Nike Alphafly, which featured thick soles and carbon plates. However, the nature of the event didn't let that record count.
Later, World Athletics introduced a rule. It required the new shoes to be in the open market for at least four months prior to the competition. This rule also aspired to thwart athletes with exclusive shoe deals from gaining an unfair advantage.
Will the 20mm sole limit affect athlete performance?
It is not exactly negative, but the athletes will solely depend on their physical abilities and techniques. Yes, a few athletes do consider this to hurt their performance, but just like Cheptegei mentioned, mental resilience and training will play a crucial role in breaking records or achieving personal bests (PB).
Well, a reduced cushion in the sole will demand more energy from the athlete. Thus, athletes need to adjust their training regimes to adapt to the new rules.
World Athletics had mentioned clearly that they want to promote uniformity. They want the athletes to rely on their power and skills, not some technology beneath their feet, that will change and evolve with time.
However, with shoe manufacturers rushing to adapt their designs, the real test will come when athletes compete under the new regulations in 2024.
