How adidas football boots fit comes down to the line. adidas boots mostly fit true to size, with two important exceptions: the Copa Mundial and the laceless versions run long. The F50 is narrow, the Predator has a roomy toe box but a tapered midfoot, and the Copa Pure has the roomiest forefoot. adidas also uses sizes in thirds, such as 44 2/3, which are explained below.
On this page you can read how each line fits and when a different size works. If you have a wide foot, also look at our page on adidas wide football boots.
What does 44 2/3 mean in adidas sizes?
adidas sells football boots in steps of about a third of a size. After 44 comes 44 2/3, then 45 1/3 and 46. That gives you more choice between two whole sizes than at brands that work in half sizes. If you are torn between the brands, read Nike or adidas: which fits wider.
You do not have to convert a third size. Choose the size from the adidas chart that is closest to your usual one and check how your toes and heel sit. If a model runs long or short, you move a third or half a step up or down, depending on what the size list of that model offers. Our size converter helps with UK, EU and US sizes.
How adidas football boots fit: do they run big or small?
That depends on the line. Retailers and sources call the F50 and the Predator regular fit and true to size. The Copa Mundial runs long. The adidas Copa Pure Elite fits true to size, and the laceless Elite Laceless runs long.
If you have a wide foot, do not assume a bigger size is the answer. That gives length and heel slip. A wider line or leather works better, as our guide to how football boots should fit explains.
How do adidas Copa football boots fit?
The adidas Copa Mundial is thick but soft kangaroo leather that stretches gradually. Sources advise half to a full size smaller than your usual size. It feels tight at the start, until the leather shapes itself to your foot. The differences between the two Copa models are in our comparison of the Copa Mundial and Copa Pure.
The adidas Copa Pure IV has a roomy forefoot, a slightly tapered midfoot and a heel that holds well. The Elite fits true to size, and if you want a glove fit after break-in, our sources suggest going half a size down. With a narrow heel, the heel can slip. The adidas Copa Icon 2 is kangaroo leather and fits true to size with a roomy forefoot.
How do adidas Predator football boots fit?
The adidas Predator has a medium-wide forefoot with a roomy, tall toe box, but the midfoot tapers clearly and is narrower than on older versions. It fits true to size and you do not go up for stiffness. Buyers report that the latest Predator is narrower than the one before: some wide feet are happy, others find it too narrow.
Plan on break-in time. Our sources say the boot softens after 30 to 45 minutes of play and sits in place after about a session and a half. The FT version with the fold-over tongue gives more room than the standard Elite, the laceless version does not. See also our comparison of the adidas Predator vs Copa.
How do adidas F50 football boots fit?
The adidas F50 Hyperfast is narrow to standard, with a tapered midfoot and low instep volume. It fits true to size for narrow to standard feet, and going up a size to fix tightness does not work well. The F50 Hyperfast EVO gives more room for wider feet, and the F50 Messi Elite has the most midfoot room of the F50s.
Sources contradict each other here: a detailed assessment says the F50 Elite is not a boot for wide feet, while another calls the midfoot surprisingly roomy. That is a reason to look at other lines first if you have wide feet.
Does adidas fit differently for kids?
The junior lines follow the adult versions, with the lower tiers League and Club. Measure your child standing, in football socks, and go by the bigger foot. For growing room and sizes see our kids football boots size guide and football boots for kids with wide feet.
How does a lower tier fit?
Lower tiers such as Pro, League and Club generally have a thicker upper and give less. The same size therefore often feels tighter than on the Elite. No source confirms that all tiers share exactly the same last, so always try a lower tier on yourself before you choose. The football boot adviser can narrow down the lines for your foot.
