The Rise of the Super Shoe: A Deep Dive Into the Anatomy of Today's Record-Breaking Footwear
The alarm blares at 4 a.m. while the rest of the world is a silent blur of blankets and heavy sleep. You step out into the crisp, biting air before the suns even up, running mile after mile through the darkness of the night. Every labored breath and rhythmic strike of your foot on the pavement is fueled by the hope of shaving a few seconds off your personal best. You have the best gels, the best hydration packs, and have invested in more top-of-the-line running shoes than most people have pairs of shorts. But no matter how hard you push, it's difficult to imagine how a human being can achieve what Sabastian Sawe did just a few weeks ago.
The 29-year-old Kenyan charged down the final stretch of The Mall in London almost a month ago, crushing the sub-two-hour marathon record by 30 seconds. Closely behind him was Ethiopia's Yomif Kejelcha, who was running his first marathon and finished in 1.59.41. Scientists often argue that such elite performance is written directly into an athlete's DNA, but on that Sunday, the biological advantage was paired with a mechanical one.
The Rise of the Super Shoe
Both runners were wearing the brand-new super shoe from Adidas, the Adizero Adios Pro Evo 3. The $500 shoe was released just before the marathon and weighs in at around 97 grams, which is about the same as a full deck of playing cards.
"The Adizero Adios Pro Evo 3 represents adidas's first-ever sub-100-gram race shoe, weighing an average of 97 grams in a UK 8.5 sample size," an Adidas spokesperson said. "The shoe was developed through what adidas described as a "moonshot brief"-to create the fastest and first-ever sub-100-gram shoe–while still delivering the stability and performance required for elite marathon racing."
Combined with carbon-fiber elements integrated into the sole that improve the shoe's stiffness, this super-shoe is engineered for those who chase records.
"To achieve that, the team redesigned the relationship between foam and carbon through the introduction of ENERGYRIM technology, alongside the latest iteration of Lightstrike Pro Evo foam, which is nearly 50% lighter than previous iterations," the spokesperson added. "Every element of the shoe was refined with weight reduction and race-day performance in mind, from the upper construction through to the laces and outsole design."
The Adizero Adios Pro Evo 3 isn't the only shoe in the game trying to help top athletes break records. The rise of the so-called super shoe came long before the marathoner broke the impossible two-hour record. Since the inception of these fascinating upgrades in running technology, studies have come out showing that wearing them can improve running economy by 2.7 percent, and brands have eaten it up.
In fact, top brands like HOKA, ASICS, and Nike, especially, have been in strict competition with Adidas for years. Nike in particular launched the category almost a decade ago in 2017 with the release of the Nike Zoom Vaporfly 4%.

"Our motivation has always been to innovate in service of athletes and sport," Bret Schoolmeester, VP of Running Footwear, told Men's Journal. "That mindset led us to the original super shoe, and it continues to define how we innovate today."
This shoe revolutionized the running industry by combining two key technologies: a highly responsive, lightweight foam and a stiff, curved carbon-fiber plate. This design philosophy reached its peak with the Nike Alphafly 3. While it's built with a robust, layered architecture that sits at 218 grams (more than double the weight of Adidas' latest model), it was this exact setup that carried Kelvin Kiptum when he set the world record at the Chicago Marathon with a time of 2.00.35.
"With Alphafly 3, the engine remains the same-the Air Zoom units, carbon Flyplate, and ZoomX foam-but an evolved recipe," Schoolmeester said. "We've refined how those elements work together so the Air Zoom units do more of the work, helping manage impact from the road and maximize energy return over the full distance, while the ZoomX, our lightest and most resilient foam, compresses and rebounds with intention. The result is a system that supports efficiency and consistency when it matters most, deep into the race."

Engineering the Modern Stride
The architecture that defined the original super shoe has become the industry blueprint. Today, the starting line of any major marathon looks like a sea of neon, maximalist foam. While every brand claims a secret sauce, the silhouettes have largely unified around a massive stack of lightweight foam and a rigid carbon plate hidden within the sole. This design relies on an aggressive, upward-curving rocker (a technology partially popularized by HOKA) that creates a continuous rolling sensation. It essentially pitches the runner forward, ensuring that no momentum is lost the moment the foot strikes the pavement.
"Super shoes are the frontier of innovation in running footwear, and those benefits show up across the entire field, from elite athletes to anyone chasing a personal best," says Bekah Broe, senior director of performance product at HOKA.
HOKA's Rocket X 3 helped bridge the gap between elite tech and the everyday runner. It serves as a nimble entry point into the world of carbon fiber, utilizing a responsive PEBA foam that snaps back the instant it is compressed. However, while the Rocket is built for high-speed agility over shorter bursts, the true marathon heavy-lifter is the brand's flagship racing shoe, the Cielo X1 3.0.
"The Cielo X1 3.0 is meaningfully lighter than a training shoe, a difference you feel the moment you're moving in it," Broe says. "The winged carbon plate and aggressive rocker that defines the Cielo line deliver real gains in propulsion and energy return, with the shoe rolling through each stride in a way that feels almost effortless."
The technical gap between the 97-gram Evo 3 and the structured Alphafly 3 shows just how far racing engineering has come. Whether you're topping podiums or heading out for a 4 a.m. run around your neighborhood, these shoes represent a chance to utilize the same innovation currently shattering world records.
