Something remarkable has been happening at the finish lines of major marathons over the past two decades - and it's not just about the athletes crossing them. According to a timeline published by Dezeen, the dramatic collapse of marathon world records is largely tied to one surprisingly unglamorous factor: what runners are wearing on their feet.
More than just footwear
The so-called battle of the super shoes has been quietly unfolding between Adidas and Nike for years, with each brand pushing the boundaries of what running footwear can actually do. We're talking carbon fibre plates, advanced foam compounds, and geometries engineered to return energy with every stride. These aren't just trainers - they're performance technology disguised as sneakers.
Most experts now agree that advances in shoe design have played a significant role in the wave of records that have tumbled in recent years. The human body hasn't suddenly evolved. The shoes have.
Adidas claims the crown
The latest milestone belongs to Adidas. The brand has now recorded the first official sub-two-hour marathon result - a barrier that once seemed almost mythological in distance running. Their Adizero Adios Pro Evo 3 is at the centre of that achievement, representing the latest chapter in a rivalry that has pushed both companies to increasingly obsessive levels of engineering.
Nike famously flirted with the sub-two-hour milestone years earlier with their Breaking2 project, but that effort didn't meet the conditions required for an official world record. Adidas, it seems, has now delivered the real thing.
Why this matters beyond the podium
For most of us, a sub-two-hour marathon feels about as relevant to our daily lives as a moon landing. But the ripple effects of this technology do eventually reach everyday runners. Innovations developed at the elite level tend to filter down into consumer products over time - better cushioning, more efficient energy return, smarter construction.
There's also something genuinely exciting about watching two of the world's biggest brands pour resources into making humans move faster. It's one of those rare corners of the fashion and sportswear world where the design decisions are tested in the most brutally honest way possible: by the clock.
As Dezeen's timeline makes clear, this race between Adidas and Nike shows no sign of slowing down. If anything, the first official sub-two-hour marathon is less a finish line and more a starting gun for whatever comes next.
