Do Yeezy Foam Runners Run Small or Big?


Over the years, I’ve been a huge proponent of Yeezy shoes, but do Yeezy Foam Runners run small or big?

The truth is as far as sizing and fit of the Foam Runners, unfortunately, these all fit differently!

Brad is going to give his sizing experience with the:

  • Foam Runner Onyx
  • Foam Runner Vermilion
  • Foam Runner MXT

… and James is going to tell us how his Ararats fit.

Then finally, we’re going to be fully reviewing the latest Yeezy Foam Runner Onyx.

Sounds interesting?

Let’s dive right into it…


Do Yeezy Foam Runners Run Small or Big?

The real issue with the Foam Runners is they only come in full sizes. For reference, I’m a US size 9, but finding your size is not going to be the easiest, especially if you’re half size because, again, the Foam Runner does not come in half sizes. If you are a half size, go up for a better fit because the foam is thicker towards the toe. If you’re a full size, stick to your normal size. Going a full size up or down in this case will likely be too big or small for you.


Yeezy Foam Runner Onyx Sizing



I grabbed my Onyx Foam Runner in my regular US size 9, and it fits perfectly. Since the Foam Runner comes only in full sizes, just go up one size. For example, if you’re a US 8.5, grab the US 9 in the Yeezy Foam Runner Onyx. They have sizes for adults, kids, and infants, so finding the Onyx Foam Runner is pretty easy for most people.

If you already have pairs of recent Foam Runners, grab the same size that you usually grab and you should be good to go. 

A lot of the more recent releases of the Foam Runner do tend to fit true to size and the good news is the Yeezy Foam Runner Onyx fits relatively true to size.

On Adidas’ website, they say that they run small and that you should go up half a size.

Unfortunately, the Foam Runner does not come in half sizes. So, for full-size people, you should go with your true size if you have regular feet.

If you’re a half size, I would recommend going up a half size and that’s what Adidas recommends to do and that’s what I would recommend doing as well.


How do the Foam Runner Ararats fit?



In terms of sizing, it’s really tricky to get it right for the Yeezy Foam Runner because there are no half sizes.

I got the Ararat in the US 10.

I think by pure chance, I just managed to get my true size when it came to these Foam Runners because I am a UK 9.5 in Adidas and this is a UK 9.5 which is a US 10.

I didn’t want to have a Foam Runner that was going to be too small and uncomfortable. This fits me perfectly, and with a thick pair of socks, it’s absolutely fine.

I was trying to think how to compare the sizing for these versus other Adidas and other Yeezy releases, and the best I could do is say that it kind of feels like a Yeezy 500. It’s quite similar physically, but it’s definitely not as snug as the Foam Runner.

There is some rubbing that occurs on the back of the heel, but I think it pretty much just has to do with the design of the Foam Runner.

I’ve definitely seen a few other people complaining or at least talking about the fact that it does rub over time.

To summarize then, if you’re able to cop the Foam Runner when it releases, then I would definitely try and go for a true to size if you can.

Take a bit of a gamble and see what happens, and if you’re unable to make it work, then you might have to resell it and get the right size.


How do the Foam Runner Vermilions fit?



Again, I’m a size 9, but I sized down to a size 8 because it turned out that the 2021 Vermilion actually fit very small.

Unlike previous pairs of Yeezy Foam Runners, the Vermilions actually fit significantly smaller than I think we all would have expected.

Actually, if you go to, they actually say to grab a full size up from what you usually grab, which I don’t think I’ve ever seen Adidas or Yeezy Supply recommend before, which is honestly probably the right move.

Again, the Foam Runner Vermilion definitely fits a lot smaller than any of the Foam Runners that I’ve ever tried on.

It’s weird that it fits so differently. Maybe this material cools differently than other Foam Runner materials and maybe that’s why they did it in China because they didn’t have this kind of foam.

Again, keep in mind that if you’re grabbing a pair of the Vermilions to grab a full size up.



How do the Foam Runner MXT fit?



I’m a size 9 and so I usually go with size 9 when it comes to the majority of Yeezy Foam Runners. If you are a whole size, I would suggest you go with your whole size.

The fit of the Foam Runner MXT is pretty similar to the Yeezy 350 v2, but if you are half size, I would suggest going up rather than going down.

If you go up a half size, you might have a little bit of room around the ankle or the toe, but it’s a really good feel, and the shoe kind of molds around your foot the more that you wear it.

If you go down, you’re going to get a little bit more rubbing around the ankle and you’re not going to have much give in the shoe.

Talking about rubbing…

I will say that you probably should wear a pair of socks that go up to at least where the top of the shoe is because if you don’t, the Foam Runner MXT is going to rub underneath your ankles.

I wore this shoe on the beach a couple of times and I had blisters all in the bottom of my ankles.

Maybe that was just me, maybe I have very sensitive ankles, or maybe my feet didn’t fit in this ankle area exactly right.

I don’t know what the reason was, but that was my experience. So, just like with Hey Dude shoes, I would just suggest wearing socks with the Yeezy Foam Runner MXT.

Now, it’s time to give you a full review of the 2022 Yeezy Foam Runner Onyx…


Yeezy Foam Runner Onyx Review

I think the Foam Runner looks crazy and I think it looks futuristic, especially the Onyx colorway. This is one of the cleanest Yeezy Foam Runners yet. 

It’s crazy you’d think that the black colorway of a shoe would be one of the first colorways to drop, but in the case of the Foam Runners, it took about two years.

Foam Runner is awesome and it actually took people about a year and a half to actually come around to this shoe, and now it’s become one of the most popular Yeezys ever.

But even though it took longer than I would have wanted for this colorway to come out, I’m just glad it’s here.

As a Foam Runner fan, this colorway is definitely up there with my top three favorite Foam Runners.


Retail Price & Resell Price

The Adidas Yeezy Foam Runners in the Onyx colorway officially released worldwide on June 8th, 2022 with a slightly higher retail price of $90.

I’m not sure if that retail price is the same across all the places that it’s releasing, but at least on the Adidas Confirmed App, this shoe is priced at $90.

I guess the price point isn’t that surprising because inflation is out of control right now and it just makes sense that Adidas is slightly raising their prices.

Don’t get me wrong, a $10 increase is still crappy, but at the same time, it could be worse.

If you’ve been following Kanye West and his Yeezy releases, you probably already know that this shoe had an incredibly limited release at one of his listening parties.

No one knows the exact number of pairs of the Onyx Yeezy Foam Runner released at that event, but it was very limited, and up until recently, this shoe is reselling for like $1000.

Now you can pretty much buy a pair of these for $150 to $180, which leads me to believe that there probably are or hopefully are a good amount of pairs of these available.


Is Onyx the new gray?


The Adidas Yeezy Foam Runner in the Onyx colorway is essentially a black Yeezy Foam Runner except, in reality, it’s not exactly black. It’s more of sort of a washed-out very dark gray.

To be completely honest, when I first heard about the Onyx and saw images of this shoe, I thought that it might be a black Yeezy Foam Runner and that’s what I was hoping for.

But seeing the shoe in person and seeing some of the updated promotional images for this shoe, this sort of dark gray color is actually really growing on me.

Diving a little bit deeper into this shoe, the entire shoe seems to come in one tone of Onyx or very dark gray.

But when you look a little bit closer at this shoe and look at it in actual daylight and not just in the lights in your house, you’ll notice that it’s not one solid color, but it actually does have a light mix of other shades of dark grays and blacks.

To be fair, it’s barely noticeable, but it’s there nonetheless.


All in all, the name of this colorway is a little bit misleading because onyx is a very dark color and this is a much lighter version of a dark gray or a black.

I think the name charcoal or something like that would have been a more fitting name, but at the end of the day, it doesn’t really matter, but just so you know, this is not a solid black. This is definitely more of a dark gray.

And if you wear this shoe with dark colors and maybe a pair of light pants, you can still get away with it. This is one of those colorways that just kind of fades into the background.

It’s not the most eye-catching piece, but that’s what I love about it. If you’re looking for a more laid-back look of the Yeezy Foam Runners, this is the way to go.


Made in China vs Made in the USA

What’s interesting about the Onyx colorway is that this shoe is actually made in China. I’m assuming it has to do with production costs or production capabilities.

But for whatever reason, Adidas and Yeezy make their mixed versions of the Foam Runners in China and all the solid color Foam Runners like the Ararats are made in the United States.

That being said, the actual physical difference between the made-in-the-US pairs and the made-in-China pairs is negligible.

In fact, there’s really not much to differentiate these shoes other than the slight textural difference that is very hard to notice and also the color difference.

Other than that, they feel exactly the same and they fit very similarly.




As far as the actual silhouette and construction of this Yeezy Foam Runner, it’s unchanged from any of the previous Yeezy Foam Runners.

You still have this very thick nose which is actually great if you stub your toes a lot. There’s just so much foam there at the tip.



You still have all the same ventilation holes on the top of the toe and along the side of the sneaker.

You still have that sort of hidden Adidas three stripes in the midfoot of the shoe and all of the little design details and the sort of sculpting of this sneaker.

The ankle collar still feels the same and you’ve got that little parting line where the two molds separated on the shoe.

Continuing around to the back of the shoe, you’ve got that same Yeezy Foam Runner heel portion which is swept upwards which actually makes it really nice to drive in because you can sort of lean into the pedal.


It’s also very nicely padded around the heel. It’s very comfortable and it does offer a little bit of heel containment, which I like.

Inside the shoe, you’ve still got that really nice textured footbed area which feels like it’s massaging your foot for the first three minutes that you wear this before you get used to it and don’t notice it anymore.




The Yeezy Foam Runner is a very comfortable shoe on foot and it’s incredibly breathable because of all the perforation holes.

The foam is not only durable, which is surprising to me, but also very soft underfoot and also pretty softer on the top of your foot because it’s the same foam.


Socks or no socks?

The one thing that I would recommend when it comes to wearing a pair of Foam Runners if you’ve never worn a pair before, it’s probably best to wear this shoe with a pair of socks.

If you don’t wear a pair of socks, the foam on the edges of the ankle collar can really rub against your skin and it can be a little irritating. Also, around the top of the heel can really rub against the back of your leg.

As long as you’re wearing socks, you should be good to go.

Bottom & Durability


Continuing down to the outsole of the shoe, you’ve got that familiar herringbone Foam Runner traction pattern. It works very well and it’s also very durable.

You can wear this shoe for months at a time and you get barely any wear on the outsole. I don’t know what kind of foam they use, but it’s like some of the softest and most durable foams out there.

Wrap up

All around, if you’re a Yeezy Foam Runner fan, then the Adidas Yeezy Foam Runner in the Onyx colorway is an absolute cop.

This shoe is awesome and it’s got all of the benefits of the Foam Runner. It’s incredibly comfortable and it’s very easy to clean because it’s made of one material.

It’s probably one of the easiest Yeezy Foam Runners to rock. I love earth-tone Foam Runners, but it is nice to have a black pair.

I would love to know your thoughts on the Onyx Foam Runners and whether this is a shoe that you’re trying to grab or whether it’s a shoe that you could care less about.

As always, thank you so much for making it to the end of this “do Yeezy Foam Runners run small” kind of article.
