Running shoe mileage calculator
When a pair of running shoes is due for replacing, from the distance on it and how much you run in it each week.
Which pair?
How the estimate works
The calculator divides the distance left on the pair by your weekly distance in it and rounds to the nearest week. It never shows zero weeks while there is distance left.
- Replacement line. Running and trail shoes 400 mi (650 km), race shoes 250 mi (400 km), walking shoes 500 mi (800 km). Set your own if your pairs last longer or shorter.
- Getting close. Starts at 80% of the line, a good point to line up the next pair.
- Rotation. Splits your weekly distance evenly across pairs. It moves the date, not the number of miles a pair lasts.

Questions
How many miles do running shoes last?
Most brands and running stores say 300 to 500 miles (about 480 to 800 km), and HOKA gives 400 to 800 km. The calculator uses 400 miles for daily trainers. Treat it as a planning line and check the shoe itself as you get close.
Why do race shoes get a lower line?
The lightest racing foams lose their advantage sooner. In one study, a PEBA super shoe lost its running economy edge after 450 km, so the calculator defaults race shoes to 250 miles of racing life.
Does rotating shoes make them last longer?
Not in total miles. Rotation splits your weekly distance, so each pair reaches its line later on the calendar. The main evidence for rotation is about injury risk, not shoe life.
Will running in shoes past the line cause an injury?
Not automatically. We could not find a study showing that crossing a mileage number causes injuries, and a 2026 review found limited effects of footwear on running injuries. Replace a pair when the outsole is bald, the midsole is creased or flat, the shoe tilts, or aches keep showing up after easy runs.
