How often should you replace your running shoes?

OK, so they can’t last forever, but how many kms do your running shoes last?

As a general rule, replace your running shoes after 300 to 500 miles (three to six months, depending on how much you run). But how long do running shoes last if you’ve lost track – or you want to be extra cautious about overuse? We'll tell you some signs to let you know you need new running shoes.

There are some external signs to look for: the bottom or sides are visibly beaten up, the treads are worn out, or the midsole is wrinkling. These are indications it’s time to give your shoes the boot, but don’t rely solely on what you can see. How often you should change your running shoes depends on a lot of different factors.

How many miles or km's should running shoes last?

When you want to know how long your running shoes last, there are some external signs to look for: the bottom or sides are visibly beaten up, the treads are worn out, or the midsole is wrinkling. These are indications it’s time to give your shoes the boot, but don’t rely solely on what you can see.

Focus on how your shoes feel and pay attention to changes over time. If your once-trusty pair leaves your legs or feet noticeably tired after each run (and you can’t chalk it up to a more intense training plan or another shift in your habits), it may be that the cushioning has lost shock absorption.

If your shoes start to fit differently than they did out of the box, that’s also a sign they’re ready for retirement. The materials have likely stretched or worn down. And don’t discount a vague sense that the ride feels different. That’s grounds for replacement, too.

How to improve your running shoes' lifespan

Eventually, even the best shoes wear out, and you’ll have to call it quits. But we'll tell you how to make running shoes last longer by taking good care of them while you're together.

First, use your running shoes only for running. Walking or standing for long periods, gym training, and other activities involving lateral motion create an unusual wear pattern — which breaks down the shoes faster. Performance running shoes are designed for one thing, and they’ll have the longest life if that’s all they do.

Also, while we don’t generally recommend dishonesty, we do suggest cheating on your favourite trainers. Keep two pairs in rotation, and alternate so you never do consecutive runs in the same shoes. You’ll allow time for each pair to completely dry and the cushion to reset between runs.

And on the note of drying: make sure you give your shoes some TLC after a rainy day. If you run in a downpour, through puddles, or in some other condition that soaks or submerges your shoes, take a few minutes to stuff them with newspaper and leave them in a warm place overnight. Avoid heat (dryer, heating vents, sunlight), as it can ruin the synthetic materials in the upper.
