Estimate how many miles are left in your running shoes and when to swap them — before dead midsole foam invites injury.

estimated shoe life
An estimate based on typical midsole durability. Aches late in a run, or a flat, dead feel underfoot, mean it's time regardless of the number.
Frequently asked questions
How many miles do running shoes last?
Most running shoes last 300–500 miles. Lightweight and carbon racing shoes wear out sooner; max-cushion daily trainers last longer. The calculator adjusts for shoe type, your build and the surface you run on.
How do I know when to replace my running shoes?
The midsole foam loses its cushioning long before the upper looks worn, so mileage is the most reliable signal. Aches that appear late in runs, or a flat, dead feel underfoot, mean it is time.
