Most beginners don't realize it, but replacing running shoes is crucial to preventing injuries. As shoes get worn out, they lose their ability to absorb shock. Hence, you're in for a world of hurt (and maybe injury). Here are the telltale signs
Monitor Your Mileage
The experts recommend replacing your shoe every 300-400 miles. Body weight affects the wear and tear of a shoe. Heavier individuals should opt for the lower 300, and lighter runners should replace their shoes around 400. Rather than tallying your miles, I recommend dividing your average weekly mileage by 300-400. I average about 50 miles per week. So, 400 divided by 50 means I should be ready to shill out for some new trainers every 8 weeks.
Feeling Some Pain
You might think it's due to injury or harder workouts. However, if you can't remember the last time you bought your shoes, they might be the culprit. Typical pain from shock occurs around the joints. Think hips, knees, or ankles. Replacing your shoes will make your run feel way better, and your body will thank you, too!
This is one of the few times that flexibility is a bad thing. If your shoe is bending every which way, it means your shoe has lost its support. Retire 'em.
