Running Shoe Mileage Calculator
Estimate how many miles are on your running shoes and when to replace them. Enter your weekly distance, the first run in the pair, and the life you expect from them.
Example values are filled in. Replace them with your weekly running and this pair’s first run.
Distance on this pair
Daily trainers are usually rated for 300 to 500 miles (500 to 800 km). Racing shoes last less.
Left in this pair
Enter your weekly running and when this pair started.
Enter the date of your first run in this pair, or the distance already on it.
Let the app count the miles.
Vitadel Run logs each run against the pair you wore and tells you when a pair is due to retire.

The distance is an estimate from your entries unless you logged it. Shoe foam, your weight, and the surfaces you run on change how long a pair lasts, so check the midsole and outsole as the date gets close.
Count the miles you never logged
Shoe foam loses cushioning with distance, not with time on the shelf. If you did not log every run, this calculator estimates the distance on a pair from your weekly running and the date of its first run, then projects when it reaches the life you expect. If you did log it, enter the total and skip the estimate.
Estimate the distance so far
Weekly distance, times the share of it you run in this pair, times the weeks since the first run. A logged total from a watch or an app replaces the estimate.
distance so far = weekly distance × share × weeks since the first run
Set the life you expect
Retailers and manufacturers rate most daily trainers for 300 to 500 miles (about 500 to 800 km), with light racing shoes below that. Cook and colleagues measured shoes keeping roughly 70 percent of their shock absorption after 500 miles of real running. Heavier runners and rough surfaces shorten the range.
distance left = expected life − distance so far
Project the retire date
Distance left divided by the weekly distance in this pair gives the weeks left, and the date follows. Treat it as a reminder to check the midsole and outsole, not a deadline.
Example: 40 km a week, first run eight weeks ago
A pair worn for every run at 40 km a week has about 320 km on it after eight weeks. With an expected life of 650 km, 330 km remain, a little over eight weeks. The calculator shows the date and the share of the life used.
Common questions
How many miles do running shoes last?
Retailers and manufacturers put most daily trainers at 300 to 500 miles. Cook and colleagues found shoes kept about 70 percent of their initial shock absorption after 500 miles of running; machine testing lost more. Lighter racing shoes wear faster, and your weight, stride, and surfaces move the number.
What if I don’t know the date of the first run?
Enter the distance already on the pair instead, from a watch app, a log, or a best guess. The calculator then projects forward from that total.
What are the signs a pair is done before the number says so?
New aches after runs, flattened cushioning under the heel or forefoot, creases in the midsole foam, and outsole rubber worn through at your strike point. Any of these means retire the pair, whatever the distance.
Should I rotate two pairs?
Rotating spreads the wear and makes the share setting useful. A pair worn for half your runs lasts twice as many weeks. Run the calculator once per pair with its own share and first run.
Do walking and casual wear count?
Yes. The foam compresses whether you run or walk in the pair. If you wear them around town, add that distance to a logged total or lower the life you expect.
