One player. One problem
Prevolve didn't start in a lab or a boardroom. It started with an injured soccer player who refused to accept that his knees had to hurt.
01.The Injury
The dream that two surgeries ended
Oliver was on track to play soccer for a living until two knee surgeries at sixteen took it away. The pain didn't leave when the game did. Every cleat he owned forced his foot into a shape it was never built to hold, and his knees kept paying for it.
26 bones, 33 joints and over 100 muscles in each foot. Conventional cleats fit them as one block.
02.The Discovery
Running barefoot changed everything
After reading Born to Run, he tried running barefoot and felt what no cleat had given him: movement without pain. The problem was never his feet. It was what the footwear industry had built to cover them
Runners with a barefoot-style forefoot strike showed about half the repetitive stress injuries of heel-first runners. Daoud et al., Harvard, 2012.

03.The Obsession
The 12,500 hours custom fit algorithm
He left college, taught himself 3D printing, and started sanding down his own cleats in a one-bedroom apartment. The first versions broke after five to ten games, so he rebuilt them hundreds of times, eventually coding a custom-fit algorithm that took him 12,500 hours to get right.
12,500 hours of code, 254 prototype iterations, and 995 logged improvements on the public log.
04.The Result
Nine years of work, in every pair
Our toes spread instead of fold, the pressure points disappear, and your feet finally do the work they were built for. Players talk about sharper cuts, fewer rolled ankles, and the kind of ground feel that makes them faster, all from a boot shaped to their own feet.
+53% performance within their first season, athletes surveyed, June 2026.

“Big brands make one shoe 10,000 times. I'd rather make one shoe, 10,000 times better.”
Oliver Brossmann, Founder
He still plays in every design
Prevolve isn't tested in a lab either. It's tested at full speed, on turf, by the founder.
Oliver never stopped playing. He still competes at a high level, and every design for the soccer cleat goes through his feet first, proven through cutting, sprinting and shooting for hours. He's learned the subtle art of design and iteration when it comes to footwear. The fit algorithm behind every pair is code he wrote himself, line by line, and it gets reviewed through every session on the pitch.
Founder-tested in play before anything ships.

From a bedroom floor to 25 countries
The dates that matter, from the first sanded-down cleat in 2010 to cleats shipped to 25 countries.
The first experiments
Oliver sands down his own cleats to ease the knee pain. They help, but break after a handful of games.
The first custom-fit cleat
His earliest real attempt at a cleat printed to the shape of a foot.
Prevolve is founded — then life happens
He commits to building the cleat no one else would make. From 2017 to 2020 the project sits untouched.
The restart
Back at it late in the year: new gluing methods, and the barefoot design principles that still shape every pair.
Printing flat, then the algorithm
First uppers 3D-printed flat in 2021. The pattern algorithm is finished in 2022.
The garage shop
Production moves into his parents' garage, and trial pairs reach an NFL cornerback.
Real production
August: out of the garage, into a warehouse. December: cleat plate durability finally cracked.
Ready for you
Heel cup comfort in March, eyelet durability in April, and this site launches with every pair guaranteed for 250 hours.
