Kids' football boot sizing chart: age, EU and UK conversions

How kids' football boot sizing works across EU, UK and CM

Children's boots are sized on foot length, not on age, and every EU or UK number on the box is simply a rounding of that length in centimetres. That single fact resolves most of the confusion parents arrive with: a UK 2 and an EU 34 are the same last, and a boy who measures 21 cm has no business in either if the specific model runs short. Age charts are useful only as a sanity check on measurement, never as a substitute, because two nine-year-olds in the same class can differ by a full size and a half.

The encyclopaedic description of football boots is deliberately plain — footwear built around a soleplate that grips a playing surface — and that plainness is the point. The upper can be marketing. The soleplate is engineering, and it is also where most UAE purchases go wrong.

What the EU, UK and CM numbers actually mean

EU sizing (also printed as "Paris point") steps in two-thirds of a centimetre, which is why EU numbers move in jumps of roughly 6.7 mm. UK sizing steps in barleycorns of about 8.4 mm, so the two scales drift apart as feet grow and never line up neatly at the half sizes. CM, usually shown as "foot length" or JP, is the honest figure: heel to longest toe, measured standing, in millimetres or centimetres.

Industry-wide, junior lasts are also built with a little built-in allowance — commonly 4 to 6 mm over the stated CM — so a boot labelled 20.5 cm is not meant to be worn by a foot of exactly 20.5 cm with no clearance. Understanding that allowance is what separates a confident purchase from a guess.

How to measure a boy's foot at home

Do this in the evening, after school or training, when feet are at their largest. Ten minutes of preparation beats a return trip to a mall in Al Barsha.

1. Tape a sheet of A4 paper to a hard floor — carpet gives a falsely short reading.
2. Have him stand in match socks, heel against a wall, weight spread evenly on both feet.
3. Mark the longest toe (often the second toe, not the big one) with a pencil held vertically.
4. Measure heel to mark in millimetres, then repeat for the other foot and take the larger number.
5. Add 5 to 8 mm of growing room, and compare that total to the CM figure on the product page.

Why the same size fits differently between brands

Lasts are proprietary. A junior Mercurial, Predator and a Decathlon own-brand boot in the same EU 32 will not feel identical, and in our own fittings the spread between the widest and narrowest junior last in one size has been consistently noticeable at the toe box and the instep. Wide, fleshy feet suit roomier synthetic uppers; narrow feet swim in them and compensate by over-lacing, which flattens the arch.

And this is where most sizing advice quietly fails — why does a chart that looks authoritative still produce a bad fit? Because it was built from averages, and your son is not an average. Treat any chart, including this one, as a starting filter and let measurement make the final call.

Kids' football boot size chart by age, EU and UK conversions

The table below maps typical ages to the UK, EU and centimetre sizes that fit them, so a parent can sanity-check a measurement in seconds. Read the age column as the middle of a range, not a rule: a tall eight-year-old often needs the size listed for ten, and a slight nine-year-old may still be comfortable one row up from his age band. Where the measurement and the age disagree, the measurement wins every time.

Age (typical)	UK	EU	Foot length	Typical stage
4–5	9	27	16.5 cm	First kicks, nursery
5–6	10	28	17.5 cm	School PE
6–7	11	29	18.5 cm	First academy sessions
7–8	12	31	19.5 cm	Weekly training
8–9	13	32	20.5 cm	School league
9–10	1	33	21.0 cm	Growth spurt begins
10–11	2	34	22.0 cm	Two to three sessions weekly
11–12	3	35.5	22.5 cm	Club or academy squad
12–13	4	37	23.5 cm	Transition to adult lasts
13–14	5	38	24.0 cm	Adult soleplates common

Figures are typical conversions, not brand specifications. Junior lasts vary by up to half a size; always confirm against the CM figure on the retailer's own page.

Which size fits a 6 to 8 year old?

Expect UK 11 to UK 12, EU 29 to 31, or roughly 18.5 to 19.5 cm, and buy the turf-soled pair rather than anything with long studs. This is the age band where football shoes for boys get bought in the biggest volumes in the UAE, largely because school teams and weekend academies start in earnest around year two. Feet at six and seven grow fast enough that a boot can be outgrown inside a single season, which is an argument for buying accurate rather than buying oversized.

Which size fits a 9 to 14 year old?

From UK 1 upward through UK 5, the chart starts to behave differently, because growth slows and the foot lengthens more than it widens. Between nine and twelve many boys move two full sizes. At thirteen and fourteen, adult soleplates and adult sizing become viable, and some parents switch to adult models in the smaller sizes to get better stud geometry — a sensible move for boys training three or more times a week on firm artificial grass.

How much growing room should you leave?

Five to eight millimetres, measured as clearance at the longest toe, and no more. Buying a size up "to last two years" is the single most common mistake in junior footwear: an oversized boot lets the foot slide, blunts ball control, and turns every change of direction into a small roll of the ankle. If a boot feels loose now, it will feel loose for the six months it takes to become dangerous.

Choosing football shoes for boys by pitch type

Match the soleplate to the surface your son actually plays on, and in the UAE that usually means turf (TF) or artificial grass (AG) rather than firm ground studs. Most school yards, community pitches and academy facilities in Dubai, Sharjah and Abu Dhabi are synthetic, and long firm-ground studs on a dry artificial surface raise the risk of knee and ankle strain because the boot cannot release from the surface. Soleplate first. Upper and colourway afterwards.

Boots are defined by their soleplate rather than their upper: the stud pattern decides whether the foot grips, slides, or overloads the ankle on a given surface. No upper material compensates for the wrong sole.

— Working principle summarised from the general definition of football boots

TF and AG: the practical default on UAE artificial grass

Turf boots — the ones parents call astro turf boots for kids — carry dozens of small rubber nubs instead of blades. They distribute pressure across the whole foot, which is exactly what a growing boy needs on a hard synthetic surface, and they work acceptably on the short-pile carpet-style pitches found at most schools. AG versions use shorter, denser plastic studs for longer-blade artificial grass, and the difference matters: AG studs on a short-pile school pitch feel skittish, while TF nubs on long-blade academy turf can slip.

Anyone shopping for boys' football boots on a budget should start here. A TF pair covers school, park and cage sessions, and in practice it is the only soleplate most UAE children under ten ever need.

FG, SG and the indoor football shoes for boys question

Firm ground football boots use moulded studs and belong on natural grass that is dry and short — relatively rare locally, though irrigated pitches exist at larger clubs. Soft ground boots with screw-in metal studs are for wet, deep turf and are effectively pointless in the UAE; for a boy under twelve they should be avoided outright. Indoor football shoes for boys use a flat, non-marking rubber outsole for futsal courts and sports halls, and demand for them has grown noticeably as cage football and school futsal leagues have expanded through 2026.

Soleplate	Best surface	UAE relevance	Suitable ages	Typical AED
TF (turf)	Short artificial grass, hard courts	Highest — schools, parks, cages	4–14	120–280
AG (artificial grass)	Long-blade synthetic turf	High — academy facilities	8–14	180–320
FG (moulded studs)	Dry natural grass	Moderate — irrigated club pitches	8–14	180–400
SG (screw-in)	Soft, wet natural grass	Rare — not recommended junior	12+ only	250–450
IN / IC (flat)	Indoor courts, futsal halls	Rising fast in 2026	5–14	130–260

How to match soleplate to age and session type

A simple rule: count sessions, not ambitions. One session a week on school astro means TF and nothing else. Three sessions plus a match, split between long-blade turf and a futsal hall, justifies two pairs — a TF or AG pair and a flat indoor pair. This is the stage where families commonly own three pairs of junior football trainers and use one, which is a waste of both money and wardrobe space.

Of course, there are exceptions. A boy training at a club with genuine natural-grass pitches does need firm ground boots, and a goalkeeper benefits from a flatter, more planted soleplate regardless of surface. Ask the coach what surface the sessions run on before spending — most academy staff will answer in one sentence.

What football shoes for boys cost in the UAE in 2026

Expect roughly AED 120 to AED 200 for a usable entry pair, AED 200 to AED 350 for a branded junior boot, and AED 350 to AED 550 for current-season signature models — figures that move with every promotional cycle. Pricing is tiered by brand and by season rather than by quality alone, and a boot from last season's colourway is mechanically identical to the new one at a meaningful discount. The smart money buys structure, not novelty.

Entry tier: under AED 200

This band is dominated by own-brand and previous-season stock at large sports retailers and hypermarkets. Soles are simpler, uppers are heavier synthetics, and durability over twelve months of twice-weekly use is the realistic expectation rather than a guarantee. For a six or seven year old who will outgrow the boot in eight months, paying more adds nothing: the limiting factor is growth, not wear.

Mid tier: AED 200 to 350

Branded junior Mercurial, Predator and equivalent lines sit here, and this is where most parents of nine to twelve year olds end up. You are paying for a lighter soleplate, better lockdown through the midfoot and a shape designed for quick changes of direction. Whether that translates into performance depends on how seriously the boy trains; for once-a-week school football it usually does not.

Premium: above AED 350

Signature colourways, knitted uppers and top-tier soleplates. Genuine benefits exist — weight and touch are real — but they are marginal at junior level and vanish entirely if the soleplate is wrong for the pitch. A AED 500 firm-ground boot worn on a Dubai school astro is a worse purchase than a AED 180 turf boot worn on the same surface. That comparison is uncomfortable, and it is accurate.

Where parents realistically save money

Buy last season's colourway, buy during the summer clearance window, and consider buying two pairs of the same TF model in consecutive sizes only if the older child is small for his age. Also worth knowing: boys sports shoes UAE retailers discount most aggressively in July and August, before the school season resets prices, so a late-summer purchase can land mid-tier boots at entry-tier money.

Foot development, stud safety and the UAE summer

Junior feet are not scaled-down adult feet, and the difference has practical consequences for boot choice between roughly six and fourteen years old. The growth plates at the heel and forefoot are open and softer than bone, the arch is still developing, and a soleplate that concentrates load under a small number of long studs can transmit real stress through those structures. Add 45°C afternoons and the case for lighter, flatter, more breathable boots becomes obvious.

Growth plates and why stud pressure matters

The mainstream clinical view is that repetitive loading on hard, unforgiving surfaces is a bigger factor in junior heel and knee complaints than any single incident. Long metal or firm-ground studs on a dry artificial pitch lock the foot in place while the body rotates — a recipe for torsional load through the ankle and knee. Turf nubs and short AG studs release earlier, which is precisely why coaches and physiotherapists tend to steer juniors towards them.

Ankle support is the other half of the equation. A boot with a slightly higher collar helps confidence, but it is not a substitute for strength work; youth academies in Dubai and Abu Dhabi increasingly build single-leg balance drills into warm-ups for exactly this reason.

Keeping feet cool at 45°C

Heat management is underrated in every guide that was written for a European climate. Synthetic uppers trap moisture, and a boy playing a 7-a-side match in August will finish with wet socks regardless — the goal is to slow that down. Mesh panels, a breathable sockliner, moisture-wicking socks changed before every session, and taking boots off straight after play all help. Two pairs rotated across a training week dry out far better than one pair worn daily.

Why does this matter beyond comfort? Because a damp boot loses shape, and a boot that has lost shape fits worse than the size chart predicted. Rotate, dry at room temperature, and never leave boots in a parked car.

Buying football shoes for kids Dubai: authenticity, delivery and returns

Buy from retailers whose returns window you can verify before paying, and treat any junior boot priced far below the AED 120 floor as a warning rather than a bargain. The UAE market is well served by brand stores, large sports chains and marketplace sellers, but the counterfeit risk concentrates in exactly the segment parents search hardest: discounted branded boots in popular junior sizes. Verification takes two minutes and saves the whole transaction.

How to spot counterfeit boots

Counterfeits fail on small details, not big ones. Check the soleplate moulding for flash or uneven stud edges, the stitching density at the toe box, the font on the size label inside the heel, and whether the product code on the box matches the code on the tongue. Ask for the retailer's warranty terms in writing. If a seller cannot confirm an official returns policy, the price is irrelevant — you are not buying a boot, you are buying a risk.

COD, delivery and exchange policies in the UAE

Cash on delivery remains widely offered and is a reasonable safety net for first-time purchases from an unfamiliar seller. Same-day and next-day delivery is standard in Dubai and Sharjah, often 2 to 4 days elsewhere. The critical detail is the exchange rule: many retailers accept size exchanges but not returns on worn outdoor footwear, so try boots on indoors on clean flooring, and keep the box until the fit is confirmed.

What to check before you pay

To close the loop on the whole chart, run this final check. Measure the foot in the evening and note the CM figure. Compare that figure to the CM on the product page rather than to the age row. Confirm the soleplate matches the surface of at least 80 percent of his sessions. Then confirm the exchange policy and the product code. Do those four things and football shoes for boys stop being a guessing game — the boot arrives, fits, and suits the pitch it is going to be used on, which is more than most junior purchases manage.
