The short answer
Brand is the wrong unit. Within Nike, the Mercurial is narrow and the Tiempo is generous; within adidas, the F50 is narrow and the Copa is generous. Both brands run true to length. The one real brand-level difference is that PUMA junior cleats run short — plan on half a size up — and PUMA width sits at generous-average.
Every parent gets told the same three things in the store: Nike runs narrow, adidas runs wide, PUMA runs small. Two of those are a model being mistaken for a brand, and one of them is genuinely useful. This page sorts out which is which, using the junior models that are actually on shelves rather than the adult boots the fit forums argue about.
PUMA's junior range runs short. Not narrow — short. It shows up across the models we have looked at: the Kids' Ultra Play runs slightly short with a snug heel, the Future 8 Play turf shoe is forgiving in width but runs short, and the laceless Ultra 7 Match LL Junior runs slightly short like the rest of the range.
That matters more than any width claim, because length is the measurement that decides whether a cleat is safe to wear. A shoe half a size short does not pinch at the sides where a child can describe it; it jams the toes at the front, and the first symptom is usually a black toenail rather than a complaint. If you are ordering PUMA for a kid who has only ever worn Nike or adidas, order half a size up and measure on arrival.
Why “Nike runs narrow” is only half true
It is true of the Mercurial, which is the Nike line most kids want because it is the one the fast players wear. Our note on the Jr. Mercurial Vapor 16 Club says it runs true to length but narrow, and that a genuinely wide foot will feel it through the midfoot. That single shoe is where the whole reputation comes from.
Move one silo across and the picture changes. The Jr. Phantom line carries slightly more forefoot volume at the same size, and the Jr. Tiempo Maestro Academy is the most generous Nike junior last we have found — closer to the adidas Copa than to the Mercurial. A child the Mercurial pinched has two more Nike options before leaving the brand.
Independent fit guides land in the same place. A 2026 retailer round-up of the widest-fitting boots includes Nike twice: the Phantom 6 Low Elite for good forefoot width and a particularly generous heel, and the Tiempo Legend Pro as one of Nike's widest-fitting options with space through the forefoot, midfoot and heel. A brand that appears twice in a wide-feet ranking is not a narrow brand.
And “adidas runs wide” has the same problem
The Copa is generous. Our note on the Jr. Copa Pure.3 calls it generous in width and true in length, and names it as the first cleat to try for a kid who has been squeezed by Nike junior models. The budget Goletto also runs slightly generous, which is why it keeps turning up as the answer for a wide-footed rec player on a budget.
The F50 is the opposite. Our note on the F50 Hyperfast League Kids calls it narrow through the forefoot and midfoot, and says in plain terms that it is the adidas line for a slim foot and the one to avoid for a wide one. The Predator sits between the two at average width, with one caveat: the fold-over tongue on the League model adds pressure across the instep, so a high-volume foot can find a middling-width shoe tight anyway.
A retailer silo guide ranks adidas the same way — F50 narrowest, Predator in the middle, Copa most accommodating — which is the spread, within one brand, that the folklore assigns to the gap between brands.

Pick by your kid’s level
The right answer changes with the level, not just the shoe size. Find your kid’s bracket and start there.
The low-risk first try at this age whatever the brand folklore says: slightly generous in width, true to length, and cheap enough that a fit mistake is not expensive.
The shoe to try when a Nike junior model has pinched. Generous width and true length, and the fastest way to find out whether width was really the problem.
Worth trying for a generous average foot at this age, with the standing PUMA caveat: order half a size up, and remember a laceless shoe has no way to snug down.

What the brands themselves say, and what they do not
Nike publishes a silo guide that maps Mercurial to forwards and wide midfielders for speed, Phantom to central midfielders and playmakers for precision, and Tiempo to comfort and control. Comfort and control is as close as a manufacturer gets to saying “this is the wide one”. PUMA's lines are described the same way: Future for creative playmakers with an adaptive fit that wraps comfortably around the foot, Ultra for speed with a lightweight, streamlined shape, King for a soft touch and durability.
Notice what is missing. None of them publishes a width. Brands describe silos by playing style, and the fit information arrives as an adjective — streamlined, adaptive, comfortable — attached to a marketing position. That is why fit folklore exists at all: there is no official number to replace it with.
It is also why the useful rule is not a brand rule. A “speed” silo in any brand is built on a tighter last, because a shoe sold on acceleration is sold on feeling locked down. A “comfort” or “touch” silo in any brand is built roomier. Mercurial, F50 and Ultra are the three speed lines; Tiempo, Copa and King are the three touch lines. The pattern crosses the badges.

Whatever the badge says, the shoe in the box is the only evidence that counts. Do this before the tags come off:
Fit with the match socks on, and with shin guards in place if the guards are the sock-sleeve kind. Under Armour's kids' guide says the same thing, and a thin house sock hides about half a size.
Press for the gap. About half an inch of space in front of the longest toe — which is not always the big toe. Do this standing, with weight on the foot.
Check the heel, not the toe, for the slip test. Have them walk, then rise onto the toes. Any lift at the heel means the shoe is too long or too wide at the back, and no amount of lacing fixes a heel that was never held.
Have them stand on one leg and bend the knee forward. This is where width shows up: a narrow shoe on a wide foot bulges visibly over the edge of the soleplate when the foot loads.
Then ask one question and believe the answer. “Does anything press?” A child who says the shoe presses somewhere is correct about that, always, and about the cause almost never.

Scroll the table sideways on a narrow screen.
Two feet on the same child are often half a size apart, which no brand accounts for. Fit the larger foot and pad the smaller one with a thicker sock if it swims. If you are already reaching for an insole to fix a fit, read the arch-support advice first — a thick orthotic lifts the heel out of the cleat's heel cup and creates the slip you were trying to cure, which the high arches page goes into.
What a width label would not tell you anyway
Three things decide whether a cleat works, and brand fit is only one of them.
The plate. A firm-ground plate on a turf field is uncomfortable and slippery regardless of how well the upper fits — firm ground vs turf cleats sorts out which plate the kid actually needs.
Whether it is laced. A laceless shoe is a fixed-volume shoe: it fits or it does not, with no adjustment. That is a bigger fit variable than any brand difference, and are laceless soccer cleats good for kids covers the trade.
Lacing pattern. A standard criss-cross is not the only option, and a heel-lock or wide-foot pattern changes how a borderline shoe fits — see how to lace soccer cleats.
Growth. Any fit decision has a shelf life of a few months at this age. When to replace kids' soccer cleats is the maintenance side of the same question.
Which is the honest summary of this whole page: the badge on the side is the least informative thing about how a cleat will fit. The silo tells you more, the plate tells you more, and the four-minute test at home tells you everything. Start from the youth cleat size chart for the number, use the silo table above to pick which shoe to order in it, and then check the shoe rather than the reputation.
Common questions
Do Nike soccer cleats run narrow?+
The Mercurial does, and that is where the reputation comes from — our note on the Jr. Mercurial Vapor 16 Club says it runs true to length but narrow through the midfoot. The rest of the range does not: the Phantom carries more forefoot volume and the Jr. Tiempo Maestro is the most generous Nike junior last we have found, closer to an adidas Copa. A 2026 retailer guide to the widest-fitting boots lists two Nike models.
Do adidas cleats run wide?+
The Copa and the Goletto do. The F50 does not — we record it as narrow through the forefoot and midfoot, and as the adidas line to avoid for a wide foot. The Predator sits at average width, with the caveat that a fold-over tongue adds instep pressure. The spread inside adidas is as wide as the gap people imagine between adidas and Nike.
Do PUMA soccer cleats run small?+
Yes, in the junior range, and this is the one brand-level fit fact on this page that holds up. The Kids' Ultra Play, the Future 8 Play turf shoe and the laceless Ultra 7 Match LL Junior all run short in our notes. Order half a size up from the size the child wears in Nike or adidas, then measure the gap at the toe when it arrives.
Which brand of soccer cleat is best for wide feet?+
Start with the adidas Copa, which we record as generous in width and true in length, and which is the first thing to try after a Nike model has pinched. If the budget is tight, the adidas Goletto runs slightly generous for much less. Inside Nike, the Tiempo is the wide-foot answer. The brand matters less than the silo.
Is it the brand or the model that decides fit?+
The model, nearly always. Speed silos — Mercurial, F50, Ultra — are built on tighter lasts because a shoe sold on acceleration is sold on feeling locked down. Touch silos — Tiempo, Copa, King — are built roomier. That pattern crosses all three brands, which is why one brand can be both the narrow answer and the wide one.
Should I size up in soccer cleats so they last longer?+
No. A cleat that is half a size long lets the foot slide forward on every stop and turn, which is how children end up with toe blisters and bruised nails in a shoe that felt fine indoors. Buy the size that fits with match socks on and about half an inch at the toe. The one exception is PUMA, where half a size up is often simply the correct size.
How do I know if a cleat is too narrow rather than too short?+
Have the child stand on one leg and bend that knee forward, loading the foot. Width problems show as a visible bulge over the edge of the soleplate; length problems show as toes pressed against the front with no gap when standing. Check the heel separately — any lift when they rise onto the toes means the shoe is too long or too loose at the back, and lacing will not fix it.

Unisport — top 10 best football boots for wide feet in 2026 — A retailer fit guide written model by model rather than brand by brand, and the source for the cross-brand width claims on this site: the PUMA King 20 Ultimate ranked first because it is "seriously wide", with room in the heel, midfoot, forefoot and outsole; the Nike Phantom 6 Low Elite described as having good width in the forefoot and a particularly generous heel; the Nike Tiempo Legend Pro called one of Nike's widest-fitting options, with space through the forefoot, midfoot and heel; and the adidas Copa Pure 4 Elite included in a wide-feet ranking despite a relatively tapered midfoot, because its wider forefoot compensates.
