Welcome to Week 15! This week we will talk about all the miles you’ve been logging on your shoes, and if it’s time to replace them.
What you should know about running shoes is that they generally last 300-500 miles. This will vary greatly depending on the type of shoe, running surface, your running gait, etc. After these many miles, even if the outsole still looks good, the midsole will have lost its ability to compress and rebound, thus no longer adequately absorbing shock. Your body will be forced to absorb more of the forces generated by running, which can lead to discomfort and injury.
Sometimes the best way to know for sure if you need new shoes is to try on a new pair. If you notice a big difference right away, it’s a sign that it’s time to replace your old shoes.
In terms of timing, now is the perfect time to break in a new pair of shoes before your big race. Remember, we highly discourage running your race in shoes you’ve never worn before.
