Shoes have a life.
We measure it.
Most running shoes are retired with hundreds of good kilometres still in them. NORMA gives every used pair a verified % life remaining, read from the Strava mileage they've already run — so a buyer knows exactly what they're getting before they pay.
Why we built this
Runners are honest people who sell into a dishonest market. “Barely worn.” “Only used a handful of times.” Everyone means well, but nobody can prove it — so the buyer discounts every listing to protect themselves, and good shoes with real life left get thrown out or sold for scrap.
We started NORMA because the missing number already existed. If you log your runs, your shoes have a mileage history. That history is the truth the market was guessing at. We simply make it legible: how far a pair has run, how much of its designed life is spent, and how much is left.
How % life works
It isn't a marketing star-rating. It's a subtraction anyone can check, grounded in data the seller can't quietly edit after the fact.
What makes a listing trustworthy
Where we're going
The mileage number is the start, not the finish. We're building a rotation tracker so runners can watch life deplete across their whole shoe cupboard, a fair-price guide anchored to life remaining rather than release date, and a clearer picture of which models actually last.
The goal is simple: fewer good shoes in landfill, and a used market runners can trust as much as a new one.
