How to Use the Running Shoe Replacement Checker
Select your shoe type and enter your total mileage to see how much life your shoes have left. Optionally add your weekly mileage to get an estimate of how many weeks remain before replacement.
Running shoe lifespan varies by type: neutral cushioned shoes last 300–500 miles, trail shoes 250–370 miles, and racing flats 190–310 miles. Once cushioning compresses past its limit, shock absorption drops significantly — increasing injury risk to your knees, shins, and ankles. Body weight and running surface also affect lifespan; heavier runners and hard road surfaces accelerate wear.
Frequently Asked Questions
Cushioning degrades before the outsole visibly wears through. If you notice knee soreness or shin splints that weren't there before, worn cushioning is often the cause.

Yes — visible tread wear, the shoe leaning to one side on a flat surface, or new aches after a run all indicate the shoe needs replacing regardless of mileage.
