Once a day at Gear for Multisport I get the question…

"How often should I replace my running shoes?"

run Unfortunately, there’s no universal answer to this question, given that many factors figure into the lifespan of a shoe: the construction of the shoe, your physical makeup, the way in which you strike the surfaces you’re running on, the Florida weather, & how often you wear the shoe.

That said, most running shoes will last between 300 and 500 miles in Central Florida.

Begin by considering the outsole, the rubber part of the shoe that comes in contact with the ground. Over time, the tread of the outsole starts to wear away, just as tires on a car eventually become bald, and you begin to lose grip on the ground below. This is the most obvious sign of wear and tear — but the outsole tells only part of the story.

What is harder to see is what happens inside the shoe when you run, in the midsole, where the cushioning and support are housed. Every time your foot comes in contact with that Minneola Trail, you compress that midsole area. It responds by absorbing the blow and returning energy to you as you begin the next stride. This process is repeated thousands of times during a run.

swimAs you can imagine, the midsole becomes fatigued over the course of a couple miles and then needs time to rebound in between runs to return to its original, bouncy state. After a few hundred miles, however, the midsole breaks down to the point of no return. You can’t see this, but you can sure feel it in a sensation of “flatness” or “deadness.” The shoe doesn’t have the bounce that it once did that day you walked out of the NTC. Little aches and pains begin to arise. You’re not injured, but your body is talking to you. It’s telling you that your shoes need changing. You should listen.

Still not sure if you should swap out your shoes? Head to GFM, and try on a fresh new pair of your favorite training shoes side by side with the ones you’ve been running in on the treadmill. Feel the difference? Often, it will be pretty clear. You’ll feel higher off the ground in the newer pair if the midsole of your current pair is compressed beyond the point of no return.
