Air Jordans run true to size in length, and that is rarely the reason a pair does not fit. The line is consistent from retro to retro; what varies is width, and the Jordan 11 in particular is narrow and never softens. Pick your model and how wide your feet run, and we will give you the size to order.
Yes, and that is the least useful true thing about them
Air Jordans run true to size. Ask the internet and you will get that answer from every single result, confidently and correctly, and then your pair will arrive and something will still be wrong. The reason is that the question and the problem are not the same thing. Length is where Jordan is consistent. Width is where it is not, and width is what people are actually feeling when they say a shoe does not fit.
That is why two people who wear the same size can have completely opposite experiences of the same shoe and both be telling the truth. The line is built on a fairly consistent last from retro to retro, so the brand-level answer really is yes. What changes is how much room there is across the toe box, and that varies by model far more than by size.
The formula
order size = your usual size + width adjustment for that model
UK = US men's − 0.5 | EU = US men's + 33
women's US = men's US + 1.5
Average width means no adjustment on any model. Narrow feet can drop half a size in the Jordan 1. Wide feet gain half a size in the 4, the 11 and most other retros. The conversions are the same ones our shoe size converter uses in its gender-swap mode, so the two pages cannot disagree with each other.
Worked example
Say you wear a US men's 10 and you are buying Jordan 11s with feet you would call wide. The 11 is true to size in length, so 10 is right on that axis, but it is the narrowest shoe in the line and the patent leather will not stretch to help you later. That makes your order a US men's 10.5, which reads UK 10 and EU 43.5. Now take the same feet and the same size in a Jordan 1: still wide, still half a size up, so 10.5 again. And with average width, both shoes are a plain 10. Same brand, same person, and the only thing that ever moved was width.
The Jordan 11 is the one to be careful with
Every Jordan runs true to size in length, but the 11 is narrow in a way the others are not, and it has a property most sneakers do not: it will not change. A canvas shoe gives. A soft leather upper relaxes. The patent leather that makes the 11 look like the 11 does neither, so the fit you get out of the box is the fit you have for the life of the shoe.
The practical consequence is that the usual advice to break them in does not apply. If an 11 is tight across the widest part of your foot on the first wear, it will be tight on the hundredth, and the only fix is the size you order. Wide feet should take the half size up, and accept a slightly long shoe as the price of a wearable one.
When the answer really is your usual size
For average-width feet in a current release, order your normal sneaker size and stop thinking about it. That covers most people and most pairs, and the elaborate sizing advice that circulates about this brand is mostly people generalizing from their own feet.
Two genuine exceptions worth knowing. Older releases of the Jordan 1 ran snugger than the current ones, so a pair from a decade ago will feel tighter than a new one, and that is the shoe having changed rather than you. And Jordan 4s made before the 2023 retooling ran slightly short, so on a vintage pair half a size up is the safer order. If you are buying new, neither applies.
If you are between sizes, go up
A sneaker that is slightly too big can be rescued: a thicker sock, an insole, lacing it tighter through the top eyelets. A sneaker that is slightly too small cannot be rescued at all, and the leather across a toe box gives far less than anyone hopes. On a patent upper it gives essentially nothing.
This is the same reasoning behind our other brand fit pages, which reach different conclusions because the shoes are different: Chuck Taylors run a half size large, so there the honest advice is to size down. Vans stretch, which changes the question again. And Yeezy has no single answer at all, because the 350 and the 700 are barely the same kind of shoe.
Frequently asked questions
Do Air Jordans fit true to size?
Yes, in length. Every current retro in the line runs true to size, so your usual US sneaker size is the right order. The question worth asking instead is about width, because that is where a Jordan actually goes wrong, and it varies by model rather than across the brand.
Do Jordan 1s run true to size?
The modern Jordan 1 does. Narrow feet can go half a size down for a snugger fit and wide feet half a size up for room across the toe box. Early releases ran snugger than today's, so a pair from a decade ago will feel tighter than a new one, which is the shoe changing rather than your foot.
Are Jordan 11s narrow?
Yes, and it is the defining fit fact about the shoe. The Jordan 11 is true to size in length but noticeably narrow, and because the patent leather upper does not stretch or soften, it will never give you the room a canvas shoe eventually would. Wide feet should order half a size up, and what the shoe feels like on day one is what it will feel like in a year.
Should I size up in Jordan 4s?
Only for wide feet, or if you are buying an older pair. The Jordan 4 is true to size today, but releases from before the 2023 retooling ran slightly short, so half a size up is the safer order on anything vintage.
Why do people disagree about whether Jordans fit?
Because they are answering different questions. Everyone agrees on length, so the confident yes you read everywhere is correct and unhelpful. The disagreement is really about width, and two people with identical shoe sizes and different foot widths will have genuinely opposite experiences of the same pair.
How do Jordan sizes convert to UK and EU?
UK is half a size below US men's, and EU is US men's plus 33. So a US men's 10 Jordan is a UK 9.5 and an EU 43, which is about 28 cm of foot. Those are the same conversions our shoe size converter uses, so the two pages cannot give you different answers.
Should I buy Jordans a size up for thick socks?
If you genuinely wear thick socks with them, yes, half a size. But size for the sock you will actually wear most of the time rather than the thickest one you own, because a sneaker sized for winter socks is a sloppy sneaker for the other nine months.
What if I am between two sizes?
Take the larger one. A slightly loose sneaker can be fixed with a thicker sock or an insole, and a slightly tight one cannot be fixed at all. Leather across the toe box gives far less than people hope, and on a patent upper like the Jordan 11 it gives essentially nothing.
