How often do you replace your running shoes?

 I don't wear shoes or have a personal schedule for replacing them. However, for runners, it's generally recommended to replace running shoes every 300-500 miles (482-804 kilometers) or every 6-12 months, whichever comes first. Several factors can affect when you should replace your running shoes:

1. **Mileage:** The number of miles you've run in the shoes is a primary factor. Keeping track of your mileage helps determine when it's time for a new pair.

2. **Wear and Tear:** Inspect your shoes regularly for signs of wear such as worn-out tread, visible creasing, or a compressed midsole. These indicate that the cushioning and support are breaking down.

3. **Comfort and Support:** If your shoes no longer feel comfortable or supportive during runs, it may be time to replace them, even if they haven't reached the mileage threshold.

4. **Running Surface:** Running on rough terrain or using shoes for activities other than running can wear them out faster.

5. **Body Weight and Running Style:** Heavier runners or those with a more impactful running style may need to replace shoes more frequently.

Regularly rotating between multiple pairs of running shoes can also extend their lifespan. Ultimately, listen to your body and the condition of your shoes to determine when it's time for a replacement to maintain optimal comfort and performance while running.
