The short answer
No soccer cleat has meaningful arch support — the whole category is built flat and thin so the foot sits close to the ground. For a flat-footed young player, look for a roomy last, a firm heel counter and a removable sockliner so a supportive insole can go in. The insole does the arch work, not the cleat.
This is a page about managing expectations before it is a page about products. Soccer cleats are deliberately minimal underfoot: a thin sockliner on a stud plate, because feel for the ball is the point. Nothing in the category offers the kind of structured arch support a running shoe does, and a cleat advertised as supportive is generally just less thin than usual.
Also worth saying plainly: flat feet in children are extremely common and frequently not a problem at all. If your child has flat feet and no pain, there may be nothing to solve. If they have flat feet and pain, that is a conversation with a clinician, not a shopping decision.
What to actually look for
A removable sockliner. This is the most useful feature by a distance, because it means a proper supportive insole can be fitted. The insole provides the arch support; the cleat provides the space for it.
A roomy last. A supportive insole takes up volume. In a narrow cleat there is nowhere for it to go, so the fit gets tight and the benefit is lost.
A firm heel counter. The back of the shoe holding the heel in place does more for a flat foot than anything under the arch, because it stops the heel rolling inward.
A turf outsole, if the surface allows. Spreads load across the whole foot instead of a few stud points, which is generally more comfortable for a flat foot.
Start here
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 roomiest mainstream junior last, which is exactly what you need if a supportive insole is going in. Also the softest upper, so nothing fights the foot.

adidas Jr. Copa Pure.3 Firm GroundThe best mainstream junior cleat for a wide foot, and a real help to a player still learning first touch.
adidas Goletto VIII Firm GroundThe sensible answer when the honest requirement is a cleat that survives one rec season and costs as little as possible.
U6, U7–U8 rec, U9–U10

Runs slightly generous in width and true in length.
Nike Jr. Mercurial Vapor 16 Club TurfThe right second pair once a kid is training on artificial turf every week, and a bad only-pair if games are on grass.
U7–U8 rec, U9–U10, U11–U12, U13+ travel & club
TF (turf)
Same narrow Mercurial last as the firm-ground Club.
PUMA Jr. Future Play TT TurfThe most comfortable junior turf shoe here, with the least protection — a fine trade for training, less so for a competitive match.

The insole is the actual purchase
If a flat-footed player needs support, it comes from an insole rather than from the cleat. That reframes the shopping problem usefully: you are buying a cleat that accommodates an insole, and buying the insole separately.
Two practical notes. A full-length supportive insole will usually need the original sockliner removed entirely, not layered over — otherwise the shoe becomes too tight and the heel sits too high. And whether an off-the-shelf insole or something prescribed is appropriate is genuinely a question for a clinician, particularly if there is pain involved.
Flat feet and cleat length
One thing worth knowing: a flat foot is often slightly longer under load than it measures at rest, because the arch flattens further when weight goes through it. That means measuring while standing, with weight on the foot, rather than sitting. Otherwise you can buy a cleat that measures correctly and is too short in play.
The rest of the fitting advice is unchanged — a thumb's width beyond the longest toe, no heel lift. How cleats should fit has the checks and the size chart has the conversions.
What about ankle support?
Soccer cleats are low-cut by design, and there is no youth equivalent of a high-top basketball shoe in the category — the collar height on the few mid-cut soccer models is about lockdown and ball feel, not ankle stability. If ankle stability is the concern, the answer is a brace or taping recommended by a clinician, worn inside a cleat with room for it, rather than a particular cleat.
In that case the roomy lines on this page matter for a second reason: a brace needs space, and a narrow cleat does not have any.

How it fits
Generous width, true length. The first cleat to try for a kid who has been squeezed by Nike junior models.
What we like
The softest upper of any junior cleat at this price, which genuinely helps a kid who is learning to receive a pass
Roomier toe box than the Mercurial or F50 lines — this is the adidas answer for a wide foot
Copa heritage means a plain, un-flashy look that holds up when the neon fades
Where it falls short
The soft upper scuffs and creases fast, so it looks worn well before it is worn out
Heavier than a speed cleat at the same price point
Manufacturer’s published specs
adidas positions the kids' Copa Pure line around comfort, ball control and natural touch for developing players
Softer upper than the Goletto line
Firm-ground plate
These are the manufacturer’s own claims, not measurements we took.
Not in any meaningful sense. Soccer cleats are built deliberately thin and flat underfoot so the player can feel the ball, and no mainstream model offers the structured arch support a running shoe does. What some offer is a removable sockliner, so a supportive insole can be fitted — and the insole is what does the work.
What cleats are best for kids with flat feet?+
Ones with a roomy last, a firm heel counter and a removable sockliner, so a supportive insole can be fitted without making the shoe tight. The adidas Copa Pure is the most accommodating mainstream junior option. If there is pain involved, see a clinician before making footwear decisions.
Do kids with flat feet need special soccer cleats?+
Often not. Flat feet in children are very common and frequently painless, in which case there may be nothing to address. Where there is pain or a clinician has recommended support, the useful thing is a cleat roomy enough to take a supportive insole, rather than a cleat that claims to be corrective.
Are kids soccer cleats with ankle support any good?+
Soccer cleats are low-cut by design, and the mid-cut collars that exist are about lockdown and ball feel rather than ankle stability. If ankle stability is the concern, a brace or taping recommended by a clinician, worn inside a cleat with room for it, is the more honest answer than a particular model.
Should you measure a flat foot standing or sitting?+
Standing, with weight on the foot. A flat foot often measures slightly longer under load because the arch flattens further, so a measurement taken sitting can lead you to a cleat that is correct at rest and too short in play.
