How to Tell You Need New Running Shoes

If you run more than a few months, then chances are you’re faced the runner’s question: When I should buy new shoes?

First, it’s not every 400 miles.  That is a ballpark answer, but it differs for every single person.  Thinking out loud, some people can get 1000, and some people get 200.  It depends on the individual.  Don’t immediately get rid of your shoes at 400 miles if you still feel good…

While chit chatting with The Dumb Runner, via twitter, I realized how common of a question it was!

The Short Answer of Replacing Shoes:

If you hurt and haven’t done anything differently in your training, it’s probably the shoes.

The Long Answer:

There is no scientific proof that running shoes should be retired after 400 miles.  Four hundred miles is the average, but many factors play a role such as:

  • Where you run (harder ground and cold can break down a shoe faster)
  • Your weight and how hard you hit the ground (causes the materials to break down quicker)
  • Your Form: If your form hits at exact points, you’ll break down those points on the shoes much faster. For instance, I land very far on my toes, but because I put a lot of pressure in a tiny pinpointed area of a shoe, my shoes break down the quickest there.  Sure half of the shoe is usable, but it’s not the half I use.

So Here are Some Ways to Determine if you’re Running Shoes have Lost their Cushion: 

First, you’re googling: have my running shoes lost their cushioning?  If you’re asking the internet and unsure, then your shoes have probably lost their cushioning…  

But here are Some Other Ways:

You’ve Run a Lot in the Shoes:

If you’ve spent at least 6 months in a single pair of shoes, they are probably reaching their limit.

If you can’t remember, a good way is to write the date on the side of the shoes.  It’s unnecessary to calculate the exact mileage of every pair of shoes you own. By knowing the date you bought them, you should be able to roughly estimate how many miles you’ve run in them.  401 miles versus 399 does not matter…

Your Body Hurts and You Haven’t Done Anything Differently:

As indicated earlier, if you’ve done nothing different but your body aches, and nothing feels good, your shoes are probably worn out.

You Can Visibly Twist Your Shoes:

Your running shoes shouldn’t be flexible. If you if you can bend and twist them, then they have probably lost their cushioning.  Even brand new racing flats are hard to twist and bend.

You Flip Your Shoes Over and Visibly See Tread Worn Out:

If you flip your shoe over and see a hole in it or worn through the tread, it’s probably worn out.  This is what most people envision as a “worn out shoe,” but just because you can’t visibly see wear marks doesn’t mean your shoes aren’t worn out.

So now what?

As someone who works in a running specialty store, I always recommend getting fitted for shoes.  Your feet and body change.  That being said, if the shoe has worked for you and the model is the same there is no sense in changing.

Every year styles are updated and changed.  This could mean they fit differently, sizing is different, or they just “feel” different.  Updates typically work for the majority of runners, but that doesn’t mean 100%.

I will say, current styles and models of shoes are never any cheaper online.  Older styles of shoes might be cheaper but they will also last less time.  If a shoe sits in a warehouse for long periods of time, it’s more likely to break down quickly.

Hopefully, you are able to get as many miles out of your running shoes as possible (staying healthy of course).

  1. I’ve had little niggles come up, and I do things like foam roll, ice, etc, but I also pull out a new pair of shoes from my closet because typically, I find that I have run a lot of miles in the shoes where it happened. Even if the issue ISN’T the shoes- at least I have a backup pair that I can try for a day or so and know that it’s not the shoes and I need to see a doc, PT, etc. I did this with my last issue, which was actually a real injury, but at least I could rule the shoes out.

    The amount of wear I get out of shoes also depends on the shoe. I feel like my Brooks PureFlow started to wear out really quickly, and the same for the Mizuno Hitogami (which I think is now discontinued). My Brooks Launch, on the other hand, seemed to last a pretty long time for a pair of shoes at the $100 price point, but then I’ve heard they didn’t last as long for others. It’s good to track mileage on shoes and know!

  2. Great post as usual, except that depending on the brand and model, you can find current styles and models of shoes cheaper online. The discounts certainly are not as prevalent as older models nor are the discounts as large, but you can find discounts. For example, I purchased the Saucony Guide 10 online for about 15% less than retail. Not great but with free shipping and no tax, I will take it. It is money I can use for a diner. Now I have found them even cheaper online elsewhere.

    1. Running Warehouse. You can always find a coupon code, more for on sale items, less for new models.

  3. The only think I’m good at it is buying new shoes, thanks for the suggestions now I feel like buying more! LOL In all seriousness, in fact I may go get something zero-drop. I just love my Merrell but after reading this I feel like it’s time to let them go and get a new pair. Cheers, Vic
