May 6, 2017. Eliud Kipchoge appears on the finish line of the Monza circuit, northern Italy. This time the sound of the engines is provided by the crash against the asphalt of the athletes who accompany the Kenyan in the breaking 2the first attempt to go under two hours in marathon distance. But it is the tires that attract attention. The feet fit the Nike Vaporfly Elite. A very high profile, a foam with an absorption capacity unlike anything seen before. And the most striking thing: a carbon plate. The promise is that the shoe saves energy when running. That is, fatigue comes later and/or the athlete can run faster with the same feeling of effort. Almost a decade ago, Eliud Kipchoge was a handful of seconds away from breaking the two-hour marathon distance. He breaking 2 It did not break the desired 120-minute barrier, but Nike had just opened a new page in the history of athletics. A space race began that has ended almost nine years after that challenge. On April 26, 2026, the moon was reached. But Adidas has put the flag. A photo for history Since 2017 we have been wondering who would be the first man to break under two hours in a conventional marathon. Eliud Kipchoge himself achieved it the following year, becoming the first to complete the 42,195 meters in less than 120 minutes. But the event, surrounded by hares, with a car making a screen to block the wind and with mobile supplies, could not be validated as a world record. In 2018, in the Berlin marathon, considered one of the circuits faster of the world, Eliud Kipchoge amazed by stopping the clock at 2:01’39”. The following year, the legendary Kenenisa Bekele was just two seconds away from that same record in one of the cruelest final stretches in history. At that time, records were already falling in pairs with the new Nike carbon plate. Athletes were breaking records at the same rate as complaints of technological doping were rising. Some, in fact, They broke contracts when they understood that they were playing at a disadvantage. With the world’s fastest man in the long distance 99 seconds away from breaking the two-hour barrier, the question of whether we would ever see this milestone was more than repeated. In 2022, Kipchoge managed to get closer and made us dream. He finally exceeded it by one minute and nine seconds. On April 26, 2026, Sabastian Sawe put the flag on the Moon. And Yomif Kejelcha propped it up. Adidas had won the space race with a photo that will go down in history. Since Nike revolutionized the market with the launch of the first Vaporfly, athletics brands went into combustion. Sneakers with carbon plates multiplied, foams softened and became more reactive. The competition arrived and Nike seemed to have fallen behind. Kelvin Kiptum in 2023 proved that we were wrong, that he was the main candidate to break the mythical barrier. He was 35 seconds away from achieving it in the Chicago Marathon but a car accident ended his life a few months later. A few months earlier, Tigst Assefa stopped the clock in a historic 2:11’53” in the Berlin Marathon. He had just shaved almost two minutes off the world record. On his feet, the Adidas Adizero Adios Pro EVO 1. The Nike-Adidas battle is on fire and in 2024 Ruth Chepngetich, dressed by Nike, becomes the first woman in history to beat 2 hours and 10 minutes. The following year, Chepngetich is sanctioned for doping but it does not affect this record. This same year in Barcelona, Fotyen Tesfay manages to go under two hours and 11 minutes and Adidas also already has the second fastest mark in the history of the women’s marathon. But the final blow was given yesterday. Only two men have gone under two hours in a conventional marathon. They both wear Adidas. From the Vaporfly to the Adizero Adios Pro EVO 3 When Nike first released the Vaporfly, all hell broke loose. Not only among the more or less amateur public, athletes verified on the spot that their shoes were not up to par with those of the Oregon brand. Until its arrival, competition shoes had been standardized in minimal profiles and low drop (the difference in height between the front and rear area). The Vaporfly blew up what was known until then. Impossible heights for the time, very soft foams and zero “feel” of the asphalt for feet accustomed to always being close to the ground. However, for some reason, they worked. The improvement was quickly attributed to the carbon plate but the plate is only one of the pieces that make the whole work. Although it was directly attributed to the plate, the truth is that that sensation of “catapult” and extreme rebound of the foot was the result of using a supercritical foam with a lot of return. In fact, the carbon served to structure the shoe and give stability to the foot. Javi Moro, head of material at the magazine Corridorexplains that these foams “are very light and have a great capacity to retain and return energy” but emphasizes that they really have not changed much in general. “They have changed the curvatures of the plate and the midsoles to generate more rocker effect,” he explains, although he emphasizes that it is more as a means to adapt to all types of audiences “because not all runners tolerate the same type of plate in the same way.” This swing is more pronounced as brands have sought the limits of the regulations. World Athletic, which organizes major events and certifies the tests and the validity of the results, prevents competition with shoes whose height between the ground and the support of the insole exceeds 40 mm. But brands play with “where” those measurements are taken (at two specific points, heel and midfoot) to play with the geometries and try to put more foam … Read more
