Adidas Yeezy Foam Runner Size Chart & Guide


Today, I’m going to give the Adidas Yeezy Foam Runner size chart, sizing guide, and review.

The Foam Runner is genuinely the most head-turning shoe that’s been released in years. When images of this shoe first came out, people really hated it and I could understand why.

But as more people started to get it in hand and as more people started to wear it, I think people are going to fall in love with this shoe.


Without further ado, let’s get right into the size chart…

2023 update – Yeezy Foam Runner MX Cinder Sizing

The Yeezy Foam Runners MX Cinder was one of the most limited Yeezys that dropped on Yeezy Day 2023 without a doubt.

Danny is going to tell us his sizing story with the Foam Runner MX Cinder and how really disappointed he is.


On Yeezy Day May 31st, I copped three pairs one of them being the MX Cinder Yeezy Foam Runners which I’m going to talk about in terms of sizing.

The Foam Runners are great for every day, walking the dog, doing casual things, going to the store, quick trips, and things like that. However, their sizing is a disaster!

It’s going to get worse when I tell you that I’m literally three different sizes in the Yeezy Foam Runner.

Let me explain…

I am a true size 10.5 or 11. I have the Foam Runner Onyx and Ochre in size 11 and they fit me beautifully. They’re my go-to everyday shoes.

Both are solid colors, but the Onyx is made in China and the Ochres are made in the United States.

The MX Cinders are a size 12 and fit me really good just like the 11 in Onyx and Ochre does, which is really confusing. Why am I going a whole size up in the MX? I guess it’s because of the MX pattern just being made I guess differently than maybe a solid color.

Some of you might say it comes down to the manufacturer where they’re produced. From my knowledge, the Onyx and the MX Cinder are both made in China and the Ochres are made in the USA.

So, why would both the Onyx and the Ochre fit the same while when they’re made in different countries? And why the Onyx and the MX Cinders’ sizing is so different when they’re both made in China?

It’s going to get even worse…

I bought the Foam Runner Vermillion in size 11 and I paid resell. They didn’t fit me and I couldn’t even get my foot into the shoe. What does that mean? 12 in the red one wouldn’t even fit me. I would probably need a 13 because they don’t even make half sizes in the Yeezy Foam Runner.

Again, I am both 11 in the Onyx and Ochre, 12 in the MX Cinder, and I would probably need a 13 in the Vermillions, which is absolutely ridiculous.

So, when it comes to the newly released Yeezy Foam Runner MX Cinder, I think it is safe to say you need to go up a full size because they do run very tight yet extremely comfortable.

My best advice is to try the shoes on before you buy them, but I know that’s so hard to do, especially when you buy them on apps.

Again, I am all over the place in Yeezy Foam Runner sizing and it is very annoying.

Did you know that Kanye West released the first Yeezy after he split up with Adidas? Here’s our review of Kany’s Yeezy Pod.

Adidas Yeezy Foam Runner Review (Ararat)


I totally understand the hate, but I love these Yeezy Foam Runners.

This shoe in general is just so wild and so futuristic. I know it doesn’t look like something that I would like. In fact, it looks like something I’d probably hate, but I don’t know because there’s just something about this that makes it lovable.


Retail & Resale

The Adidas Yeezy Foam Runner Ararat released on June 26th in the United States only as a Yeezy supply exclusive for a retail price of $75.

Even though no one saw the Foam Runner coming and it was in extremely limited quantities, I would not be surprised if Adidas decides to re-release the Ararat Colorway on their website or in larger quantities.

However, if they don’t decide to re-release this colorway in particular, they’ve got more colorways in the pipeline that they’ve already sort of leaked.

Until this shoe either restocks or more colorways come out of the Yeezy Foam Runner, I think the resale price is going to hover between 250 to 300.

I totally understand this is a lot of money especially when the shoe retailed for just $75 bucks.

So, if you’re really interested in grabbing a pair of Yeezy Foam Runners, while it is tempting to maybe spend the resale if you’re really into this shoe, I would probably wait it out because either this shoe will get restocked or you’ll have a ton of different colorways to choose for retail.

Again, unless you really have a special occasion that you want to wear this sneaker to, I would wait.

Let’s get into the sizing and fit…



Unfortunately, sizing on the Yeezy Foam Runner is a little bit tough because this shoe does not come in half sizes and it only comes in full sizes just like the Yeezy Slides.

I was lucky because I was a size 9 and a size 9 is a full size and so I was able to go with my true size.

But I will say if you are a half-size, you might want to go up half a size. The reason I say that is because the Yeezy Foam Runner does seem to fit a tad small.

So, actually, if you go up half a size, it might fit you perfectly. I got to be honest though that grabbing my true size didn’t really cause me any problems at first.

Over the week of wearing this shoe, I did find that there was actually some space around the heel and I don’t know if that’s because it started to flex from wearing it or whatever the case was.

Honestly, it felt a little too big in the ankle area, but sometimes, it feels too small. And because it’s a foam runner and there are no laces on this shoe, you really can’t change the fit.

Maybe the foam expands or contracts depending on the temperature outside and maybe it’s all in my head.

Large Ankle Fit


Moving upwards on the shoe, you’ll notice this ridiculously large ankle area. One thing I actually really did like about the fit of this shoe is how large the ankle opening is.

So, unlike the Yeezy 380 for example, the large ankle opening and the thin foam around the ankle all make the Foam Runner super easy to get your foot in and out of.

But as I always suggest, if you had the chance to try this shoe on first before you buy it, I would definitely still do it just to make sure the sizing that you’re grabbing is right for you.


As far as comfort goes, I was relatively impressed. The Foam Runner is an incredibly comfortable sneaker if you’re just wearing it for lifestyle wear.

This shoe still feels like a foam sneaker and it still kind of feels like a pair of Crocs.

But I do have to say that the foam is much softer than a pair of Crocs and because of that, it’s a much more comfortable underfoot experience.

I’m really not joking when I say this, but it genuinely feels as soft as Boost underfoot and that’s something that surprised me.

Wearing this for hours every single day, I still found it incredibly comfortable. The foam just gives underneath your foot and it really feels like you’re standing on some pillows, but it doesn’t give too much to where you feel the ground underneath.

It really feels like you’re wearing a pair of shoes and not a pair of slippers.

Moving around to the back of the sneaker, you get to the highest point of the shoe which is the heel which could also act as a pull-tab.

The heel area of the shoe is also swept up like a pair of 380s and I’ve got to say that definitely makes walking in this shoe a little bit easier and a little more comfortable.


Driving in the Foam Runners

An odd detail on this shoe that I never expected to like or never even really thought about in that way was the fact that the heel of the sneaker is swept upwards.

That definitely makes these shoes easier to walk in and that’s still true.

But something that I didn’t realize is that driving in this shoe is actually insanely easy because of this sweep-up. I know this is a small thing, but it really was surprising to me.

On most shoes, you’ve got a hard edge or a hard angle on the heel, and so when you’re pressing on any kind of pedal, your foot kind of falls into the pedal.

With the Foam Runners though, you can slowly roll your foot into the pedal and you get much more smooth acceleration and braking.

I really wish every shoe had this sweep-up because it just makes driving so much easier.

With Socks vs Without Socks


As comfortable as this foam is in a pair of socks, it’s very uncomfortable on bare feet.

The reason that I didn’t like wearing this shoe without any socks on is because it ended up chafing my ankle just a whole bunch. It was a really painful experience just in the ankle area of the shoe.

But because the foam has a little bit of a sticky texture to it, it can catch your skin. And when your ankle is rubbing up against the heel portion a lot when you’re walking or maybe wearing the shoe all day with no socks on, it can really rub your foot raw and that’s what happened to me one day when I decided not to wear socks.

Speaking of wearing socks with the Yeezy Foam Runners, I decided to go full X games mode and rock the brand-new Apothecary Tie-dye Socks.

But why is Kanye called it a Foam Runner? Doe this mean the Foam Runner is good for running?


Is the Foam Runner Good For Running?

I tried running in the Yeezy Foam Runner and it was terrible. I definitely wouldn’t recommend that to anyone. It was like running in a pair of Crocs. It was clunky, it was uncomfortable, and it didn’t look good.

So, I feel like the naming doesn’t really fit the shoe.



Finally, moving to the bottom of this one-piece construction sneaker, you’ve got the interesting herringbone-style traction pattern.

Even the herringbone-style traction pattern on the bottom of this sneaker seems super organic. I think there are actually a couple of reasons for that.

One, it just fits with the style of the sneaker, which makes sense. Two, I think there were actually some molding or manufacturing constraints.

Hidden in this little indent on the heel of the shoe, you’ve got the Adidas’ three-stripes logo.


Durability-wise, the forefoot of the shoe definitely has some light wear to it but it’s much less than I would have expected after wearing a shoe for a week and a half and only really walking on concrete and pavement.

The rest of the outsole is barely worn down. It’s incredible how well this foam is standing up to this wear.

Obviously, because the foam is the same on the upper of the shoe as well, the upper is also very durable.

I’ve scratched the toe of the sneaker against a ton of different things, I’ve scratched the heel a bunch, but there’s really no major scratches or even signs of wear.

It’s really blowing my mind how durable this shoe is especially when it’s a foam shoe and foam is not naturally a durable material.

So, for the amount that I’ve worn this shoe, the wear is surprisingly low.



At a glance, the brand-new Yeezy Foam Runner box does look pretty similar to other Yeezy boxes except for the fact that it doesn’t have any printing anywhere on the outside of the box.

It’s definitely smaller than most of the other Yeezy boxes that you’re used to and it’s probably closest to the Yeezy Slides box.

What’s interesting about this box is that it’s not actually a pullout like most of the other Yeezys. Instead, it’s actually a flip-top box.

On the inside of the box, you’ve also got Foam RNNR printed on the top and the side of the box.

Rounding off the box, on one of the sides you’ve got this little size tag that comes in white that literally just has the size and the UPC number.

I actually think Kanye and Adidas are pushing towards sustainability and being made in the United States. So, because of that, the box is a little bit simpler than we’re used to, but I could be wrong about that.

Let’s get to the sneaker itself…

Yeezy Vs. Crocs

The Yeezy Foam Runner has a one-piece construction that a lot of people just compare to a pair of Crocs. In a lot of ways, I think that’s a very fair comparison.

When you get the shoe in hand, it definitely has a Croc-like feel to it and the foams feel pretty similar.

But obviously, it looks nothing like a pair of Crocs. It actually looks more organic. It looks a lot like a kind of a hanging wasps’ nest. I don’t know why I think that but that’s really what first comes to mind when I look at the shoe at least sideways.


The Yeezy Foam Runner is made up of a mix of standard foam and also some sort of algae-based material all taken from Kanye West Wyoming.

That mix of materials actually makes this shoe incredibly soft and surprisingly durable, but I’m not 100% sure if it’s antimicrobial.

The foam also has this interesting light texture to it. It reminds me a lot of painted walls. I know that’s a weird comparison to make, but it has that sort of very lightly dimpled texture.



The Foam Runner is insane-looking. It looks nuts and it looks like it was grown, which I guess in a way it kind of was because it’s algae, but it doesn’t look like anything else that anybody else is wearing.

I’m sure that it’s not appealing to everybody, but for a person who loves sneakers and loves wearing things that people stare at, this was really fun to wear.

This shoe is an incredibly eye-catching sneaker and that’s why I liked it so much.

Objectively, it’s not a beautiful sneaker and I don’t think this is going to win any design awards at least not from a standard design award point of view.

But from the point of view of a shoe that’s different and futuristic, I think this is a really cool sneaker and I love the way it looks because of that.


It’s really amazing to me what the Yeezy team did with one piece of foam and how crazy they made it look. I think whoever CAD modeled this sneaker deserves an award because this is excellent CAD modeling.

Whether you like this shoe or not, you can’t deny that this is a head-turner and this is a shoe that you can’t really forget.

As you move back in the shoe, the foam gets progressively thinner. However, if you look at it from the top, you’ll notice that there is a slight inward curve on the medial side.

Again, this shoe is made up of one piece of material and based on the injection point at the toe which is where they injected the material into the mold, I would assume that this is an injection-molded EVA shoe.

Draft Angles


When you create something in an injection mold that’s one piece like this, you have to have multiple actions.

Actions are the pieces of material that are inside the mold that have to be removed in order to remove the shoe.

And because of that, you actually have to design into your design things called draft angles which allow those pieces of the mold to be removed.

The need for drafting obviously varies depending on the stiffness of the material and how hard it is to actually pull the piece of the mold out.

But no matter what you’re creating, even if it is a soft piece of foam like this, you always have to have some kind of drafting.

The reason that I think the traction kind of fades into the upper on the heel is not only aesthetic. I think it’s because there actually is a draft angle there and you have to be able to pull the mold off the bottom of the shoe.

That might not be the case, but I wouldn’t be surprised if that’s one of the reasons why.

Lockdown & Protection

Why is the foam thick around the toe?


The reason for that is to really hold your foot in place. If they made the thickness of the foam the same on the toe as it was in every other part of the shoe, your foot would kind of just be floating around in there.

Surprisingly, even if this shoe has a large ankle opening, your foot never actually slides out of the sneaker and I’m not sure if that’s because of the way that the foam kind of hugs your foot or maybe it’s because the ankle opening is kind of thin so your foot never really has a chance to slide out.

So, for whatever reason, when you want to put the shoe on or take it off, it’s super easy. When you don’t want the shoe to come off, also not a problem.

There were a few times where my toe actually jammed into the foam in the front of the shoe when I was swinging my foot forward a little quickly and that could be a little uncomfortable.

However, if you did actually end up kicking a wall or something, the foam really does deaden the blow so you don’t ever really stub your toe.

Another kind of interesting detail is that the foam is also textured inside the shoe especially around the upper to hold your foot in place.

Holes & Ventilation


I also really love the movement and the shape that the holes create. They really give this shoe a very wave-like look and, again, the shoe looks super futuristic and organic.

Obviously, because of the perforations and the holes in the upper, you’re not going to have any overheating issues at all, but you might get a little cold in the winter. Other than that, it’s a great sneaker.

There is always ample airflow and it never feels like you were getting too hot in this shoe even in a foam that would feel hot if there weren’t these perforations.


Moving farther back in the shoe, you’ll notice that you’ve got these three holes that get progressively larger as you move towards the heel.

These back two holes actually remind me a lot of the ovals on the Yeezy 700’s midsole. I’m sure that was on purpose and I really loved that they incorporated that detail into this shoe.

Another interesting detail is that the hole placement and the general overall sculpting of the lateral side of the shoe is pretty much exactly the same as it is on the medial side.

The toe of the shoe is very thick and bulbous and will probably draw the most attention because it looks a little weird on foot.



Around the top of the ankle area on the inside of the shoe, you’ve actually got this debossed text that says Foam RNNR, the size of the shoe, and then made in the USA.

That detail is essentially the size tag for the sneaker because while this shoe does come with a sticker on the inside when you first get it, once you pull that out, there’s really no way to tell what size shoe is unless you look at that detail like I mentioned before.


The inside of the shoe is textured especially on the footbed which is actually pretty similar to a pair of Crocs.

I’m going to be honest with you, the texture on the footbed wasn’t that intense of a texture to where it really made a difference.

Vs Yeezy 700 v3 & 500

Aesthetically, the shoe is wild and it’s very futuristic. But what I like about it is that it incorporates a lot of design details from other sneakers in the Yeezy line.

In my opinion, this shoe kind of looks like what would happen if you mashed a Yeezy 700 v3 with a Yeezy 500 and then made it foam.

In Pictures

The Foam Runner is almost like an off-white. What’s interesting is when you take pictures of this shoe, in some pictures, it looks completely white and in other pictures, it looks like a very light tan.

It’s one of those weird Yeezy colors that just looks completely different in pictures than it does in real life. I’m fine with that because it really kind of changes based on the lighting that you’re looking at it in.

All in all…

The Yeezy Foam Runner is so well designed when it comes to fit, stability, and comfort. The 3D modeling and surfacing on this shoe is so intricate it just blows my mind.

As you could probably tell from the name, Kanye is continuing his biblical naming of Yeezys. This shoe is called the Yeezy Foam Runner Ararat.

Biblically, Ararat is where Noah’s Ark ended up after the flood. I think there’s no coincidence that this shoe kind of looks like an ark or a boat of some kind.

I hate to say it, but I’m in love with the Foam Runner. I love everything about it, I love the manufacturing details, I love the materials used, and I love the ridiculous aesthetics.

While it’s definitely going to be a polarizing sneaker forever, I think people will really start to understand why this shoe is so cool.

Now it’s your turn to let me know what you think of the Adidas Yeezy foam Runner and whether you grabbed a pair on Yeezy Supply when they dropped or whether you’re planning to grab a pair for yourself.

Let me know in the comments sections down below.

So, that’s it for this Yeezy Foam Runner size chart. If we missed anything, please don’t hesitate to point that out. Happy Yeezing, everybody.
