Like any product, running shoes wear down over time. How fast this happens is determined by your foot type and your running style. Road running will wear out your running shoes more quickly than running in terrain.
A heavy runner will wear out his shoes faster than a lighter, neutral runner who runs every other day.
How often should you change your running shoes?
Each running shoe wears down differently depending on your running style, how often you run, and the shoe’s design.
You have to start looking for a new pair of running shoes if:
- Parts of the outsole are so worn that you can see the softer foam underneath
- The midsole is too weak and collapses easily when you run.
- You can see longitudinal creases in the midsole
- The heel of the shoe no longer provide good enough support.
- You have increased muscle soreness after running
How many miles before you change running shoes?
As a general rule, consider replacing your running shoes between every 400 to 500 miles. However, if you do not increase muscle soreness when you run, you may use them longer without increasing the risk of injury.
