Questions
How many kilometers can a running shoe last?
Most road running shoes are retired somewhere between 500 and 800 km (300 to 500 miles), but it depends on the shoe, your weight, your stride and the surface. In Outsole you set your own goal for each pair and get a heads-up at 80% and again at 100%.
Does Outsole record my runs?
No. Outsole picks up runs from Apple Health, so anything your Apple Watch or a running app saves to Health shows up. You then assign each run to the shoe you wore, or accept the suggestion. You can also add a run by hand.
Can I import my shoes from Strava?
Yes. Connect Strava once and Outsole brings in your shoes and their existing mileage, so you do not have to start every pair from zero.
How does Outsole know which shoe to suggest?
You give each shoe a job, such as daily trainer, tempo, long run, race or trail. Outsole learns what each pair is actually used for and suggests the best fit after every run. It also points out gaps in your rotation and when to start a replacement.
How does the surface breakdown work?
Surface analysis is optional. It matches a run's route to OpenStreetMap to work out how much was road, gravel or trail. To do this, the route is sent to public OpenStreetMap servers. Turn it off in Settings and nothing is sent.
Where is my data stored?
Your Health data, runs and routes stay on your device. Shoes you add (brand, model, total distance and your ratings) are shared anonymously, without a name or email, to help build the shoe catalog.
Which devices and languages are supported?
Outsole is for iPhone and needs iOS 26 or later. It is available in English, German, Spanish, French, Italian, Japanese and Portuguese (Brazil).
