Adidas unleashes the 97g revolution: racing shoes enter a new era
The relentless pursuit of speed has reached a new, almost absurd, level in the running world. Adidas is leading the charge with the Pro Evo 3, a shoe boasting a staggering 97-gram weight – a development poised to redefine what’s possible on the track.
A weight loss that matters: 30% lighter, 1.6% more efficient
After three years of intense R&D, Adidas claims the Pro Evo 3 is a full 30% lighter than its predecessor, thanks to a revolutionary new foam and a minimalist carbon plate design. This translates to a measurable performance gain: a 1.6% improvement in ‘running economy,’ meaning runners expend less energy per stride – a critical advantage at the elite level.
The technology isn’t just about shedding weight. The new Lightstrike Pro Evo foam, combined with the strategically placed carbon plate, is engineered to maximize energy return, converting impact into forward momentum with unprecedented efficiency. It’s a subtle shift, but one with potentially seismic consequences for marathon times.
Sabastian Sawe, Kenya’s fastest marathoner, will be the first to test this technology during the London Marathon on April 26th – a critical proving ground for any performance-enhancing innovation. A limited run of just 200 pairs, priced at $500, is available today, marking a deliberate attempt to maintain exclusivity and highlight the shoe’s handcrafted-like production process, limited by the constraints of mass manufacturing.
But the Pro Evo 3’s impact extends far beyond elite athletes. The global running market is projected to hit nearly $70 billion by 2032, fueled by a surge in popularity among Gen Z runners – a demographic that accounted for 25% of the 2025 New York Marathon participants, a significant jump from 17% in 2022. Adidas’s more accessible Evo SL, selling over 10 million pairs by the end of 2025, further demonstrates this trend.
The race to the sub-100 gram mark underscores a fundamental shift in the sport. A single gram reduction can shave crucial seconds off a marathon time – a detail previously confined to the obsessive calculations of serious competitors. And as Patrick Nava, Adidas’s Innovation Chief, noted, the brand isn't stopping there. Prototypes are already in development, pushing towards an even lighter 50 grams – a goal considered almost unattainable, yet relentlessly pursued.
“It’s as close to handcrafted as it gets when it comes to mass production,” Marc Makowski, Adidas’s innovation chief, explained, drawing a parallel to the meticulous process of crafting a luxury automobile. “Once you touch it, it honestly feels weightless. It’s set a new bar when it comes to both being the fastest and the lightest shoe at the same point in time.”
The Pro Evo 3’s arrival isn’t just about shaving weight; it’s about fundamentally rethinking the relationship between shoe and runner. Adidas’s investment in footwear technology is a clear signal: the race for speed is far from over, and the future of marathon running may very well be defined by a shoe that weighs less than a pound.
