Running and jogging offers exercise for millions of people every day. It improves our physical health, helps to prevent obesity and even helps us feel better. When possible, we need to take steps to prevent running injuries. Knowing when to replace running shoes is one way to do it.
Traumatic injuries are much less common than overuse injuries, especially overuse injuries of the feet, ankles, and legs. Running shoes are really the only equipment you have to protect you from the impact on your feet from taking thousands of steps with each run.
Your running shoes will wear out over time. The conventional rule of thumb is to replace them every six months or after every 500 miles you run. Having said that, people of different sizes, or those with different foot anatomy or stride patterns might wear out their shoes differently.
Inspect your running shoes to see if they are wearing out in certain areas faster than others. For example, if you overly pronate, you will probably see more wear on the inside of the soles. An added benefit of checking for uneven wear patterns is that the wear patterns can help you select the appropriate types of running shoes for your feet.
