"Theyre FINE! Still got a thousand miles in them!" - He lied

Those look like leg pain incarnate! I used to run every day for a few years and would get through 3 pairs of shoes at least in a year. Depends on the shoes but they always started affecting my body detrimentally between 600 and 800km, I think the best ones I had may have lasted to 900 but it wasn't the norm.

Yes they may be expensive but you can find bargains if you look and the cost is worth not fucking your legs up IMO.

When you gotta tape 'em together that should be the signal that they need to be retired lol

As others have said, it's usually the Midsole foam going flat that causes the issues. That usually happens long before any wear is visible. I used to do 600-800km in regular running shoes. After that, knee and hip pain set in pretty predictably.

But changing shoes twice a year is super annoying, so I've switched to barefoot shoes. Those don't have a midsole to begin with, so you can wear them until they literally fall apart. My current pair of Xero Shoes is on about 2k km or so and still going strong!

Generally [source? I've heard it] it's recommended to change them every 600km to 1000km. The issue is not only the upper fabric but the state of the soles, that tend to lose grip and shock absorption and that makes you prone to injuries. But it depends on so many factors (weight, where you run, shape of your foot...)

That being said, the feeling you get using them should really tell you if they need to be changed. If you feel like hitting bricks when you run and your knees feel sore, maybe look for another pair.

I'm sure people at the gym are quite happy to see a dedicated person. Nobody gives a fuck about the state of your shoes, aesthetically speaking.

When I ran long distance in high school I’d replace my shoes every year, over xc and track they probably had around 800km on them, some years a bit more others less. I learned quickly that changing brands or even models from what worked for me was bad so always got the Mizuno waveriders that were available that year.

As others noted you’ll feel the midsole start that lose its cushion well before you see wear in it. Even when it looks like it has bounce, it may not be providing what you need to cushion the forces from running (a normal pace can see many times your body mass as force on your foot as you and you want to absorb a lot of that to not ruin your knees and hips).

how can you run with a toe box that narrow?

it hurts even to look at 😖

I usually get around 1200km out of my pairs, but I also tend use them longer than ideal. Some will last longer than others, e.g. I had a pair of saucony triumph were the foam held up very well.

Generally it is not the upper or outsole that makes retiring the shoes necessary (they'll still look visually fine), but the midsole going flat. Which is kind of the point for which one buys specialised running shoes: the shock absorption and energy return the midsole foam provides.

For me the sign that a shoe is nearing the end of its useful life is usually that I start feeling the impact more in my knees after longer runs. But imo getting a second pair and still using the older one occasionally let's you get a bit more mileage out of your shoes. Also helps with comparing new vs old.

Generally I agree that running shoes are expensive, and I was surprised how much it ends up costing if you run serious mileage. But there are ways to save money and I usually spend between 50-80€ on my daily trainers, which is roughly a bit below half of the sticker price.

Buy online, look for sales at the end of the season and before new releases, buy last years models, and be flexible. For buying online to get the size right look at the cm sizing (or jpn sizes that equal cm), which for me so far has always been spot on, where EU sizes very. Also some models are usually good value, like for example the puma velocity nitro (version 1,2 or 3 doesn't matter too much so, all are solid).

I'm not sure if estimated distances have much use. Everyone wears different shoes, has a different body, different running style and runs in different conditions and on different surfaces. Shoes will wear differently based on all of these factors and a pair that lasts longer for one person might not last as long for another. I don't pay attention to how far I've run in a pair of shoes and just replace them when they're no longer comfortable or easily repairable. So I would say: if they're causing you discomfort or you're changing your running to accommodate them then it's time to move on. Both of those things could cause injuries. If you're still enjoying running in them then maybe you can wait a little longer.

Holy, poor things! They look half-dead and the other half is on death's door too...

The continental rubber on adidas shoes lasts forever....

The rubber on their top end shoes like takumi sen and pro 3 is only 1-2mm thick but i've hit 800-900km in them

Also i'm a pretty light person so i dont wear out the foam much

You've gotten a lot of great responses already. Basically, the weak point in a shoe is the foam, and you start to feel the foam go before you see it. That's one reason it's nice to have a few pairs of shoes to rotate through. You can run in one pair, and the next time you do a similar length/time in the other pair, and you'll be able to start to feel when your ankles/knees/back or whatever get sore for no reason.

In terms of the distance you get, it really depends on speed, your weight, your technique (heavy heel strikers probably wear through shoes quicker), and the surface you run on. Possibly the biggest factor is the amount of midsole foam, though. The foam stilts that are popular these days may only last you 400 km, while a more typical shoe gets 800 km.

Like another commenter said, "barefoot" shoes can last a very long time. You probably don't want to go all-in on those unless you want to do some more homework on them, but it's something to consider if you are budget constrained.

What I do now is just stick to a brand that I know works for me. Shoes are built on "lasts" which are basically a foot-like form. Traditionally, they'd be a wooden thing that a cobbler would wrap leather, etc, around. Now, it's basically just the 3D foot model. If you get 2 shoes built on the same last, they are going to fit your foot similarly, so it's not so bad to buy online. They make new model numbers every year or so, and when a new model is in, the old model goes on sale. When they got 50% off, I'll buy a couple pairs. Obviously that only works if you have the money/space to do it, but it is helpful.

I use mine for around 800km. I use 2 sets per year, but honestly I should probably switch sooner than I actually do.

You got alot of answers already. After they have passed the life as a running shoe you can still use them as a regular walking shoe, gym shoe, casual whatever.

Don't throw them away just because someone they only last 700-900km as a running shoe.

I'm a bigger guy (over 200 pounds) who runs marathons so my concern is the cushioning and the impact on my feet. I put a 500 km limit on my running shoes, after that they graduate to walking shoes or general gym shoes. My go-to are Asics, and I wait until a new model comes out and then buy last season's shoes at a discount, anywhere from $60-$110 for a pair depending on what color I want.

My Mizunos (Wave Riders) usually last between 900 and 1100 km. The moment I start having niggles in my knees or hips, I know it's time to move them to my yard work rotation. Seriously, it's not worth tisking an overuse injury running in worn-out shoes, especially ones that provide such a good value as Mizunos.

Hard to generalize. I've had two pairs of Brooks Defyance shoes last me 1,500km. A pair of Brooks Ghost only made it to 1,000, and the top mesh of my Sauconys ripped after just 700 (though the soles would have still served me longer – maybe i should have tried taping them...)

I get 5-800 km of of my shoes, I'm generally pretty hard on heels, with a heel strike and a short left leg. I only run, and I do it close to 90km a week, so rotation, and discount shoes are the way.

I run 500-700km in my shoes before they become my walking shoes. The shoes just can't take it much more and I start to lose traction or feel some discomfort in the feet.

Running shoes are definitely expensive, but if you're running a lot then the possibility of injury exists so I like to be on the safe wide with my "equipment" which is mostly the shoes.

I have a pair of Altra Rivera 3 that have ~1500km. I am not sure there is any rule (except for marketing) saying you should change your shoes every x kms. I have a friend running ultras in >500km shoes because they are more comfortable and fit better.

IMO, you should change your shoes when they start to get uncomfortable

That little damn hole by the pinky toe is the Bane of my existence. No matter what I do that little bastard pops up.

Yeah, um, those look pretty beat. I've heard 300-500 miles (~500-800km) for running shoes. I don't own a car, so I walk a lot, and had been replacing my shoes every 3-4 months since I was wearing a single pair for almost everything. I recently decided to buy one pair for walking and just casual use, and a second pair that's just for running.

I have definitely had times in the past where I began to notice some minor aches when running, so I bought a new pair of the same shoes, and the aches disappeared!
