Running calculator
Shoe mileage calculator — replacement range and date
Start from the 500–800 km running-shoe guideline, see every adjustment for shoe type, body weight, and surface, then estimate distance and date remaining.

Adjustments applied
The 500–800 km band is multiplied by shoe type, surface, and body-mass factors. The same factor moves both ends, so the result stays a range rather than false precision.
Keep this pace on file — watch it drop as training lands.
Free — no card, 30 seconds. Your result comes with you.
A guideline, not an expiry date
No trial shows that replacing shoes at one exact distance prevents injury. Retire a pair earlier when the outsole, fit, comfort, or ride changes materially; a shoe that still feels sound does not become dangerous at midnight on the estimate date.
