Asian sizing runs notoriously different from EU, UK, and US standards. Here's the truth, with foot length and chest measurements so you order once and don't ship it back.
Football boots run snug. The leather/synthetic stretches a half size over the first 2–3 wears. Below is the conversion across Asian (CN/JP/KR mondopoint), EU, UK, and US Men's.
| Asian / JP / KR (cm) | EU | UK | US (Men) | Foot Length (cm) |
|---|---|---|---|---|
| 23.0 | 37 | 4 | 4.5 | 23.0 |

Nike Mercurial / Phantom GX — runs narrow and snug, especially in the forefoot. If you have a wide foot, go up a half size or look at the Tiempo line.
adidas Predator / X Crazyfast — true to size but slightly longer in the toe box.
Puma Future / Ultra — the FUZIONFIT collar runs tight; same length as Nike but more accommodating across the midfoot.
Mizuno Morelia — Japanese last, made for narrow Asian feet. If you usually wear Nike, stick to the same size.
An "Asian L" is roughly an "EU/US M". Authentic player-issue cuts run tighter than fan replicas. Read the chart, then read the brand notes.
| Asian | EU | UK | US | Chest (cm) | Height (cm) |
|---|---|---|---|---|---|
| S | XS | XS | XS | 86–91 | 165–170 |
| M | S | S | S | 91–96 | 168–173 |
| L | M | M | M | 96–101 | 171–176 |
| XL | L | L | L | 101–106 | 174–179 |
| XXL | XL | XL | XL | 106–112 | 177–183 |
| XXXL | XXL | XXL | XXL | 112–118 | 181–187 |
| 4XL | XXXL | XXXL | XXXL | 118–124 | 185–191 |
Replica (Stadium / Fan) — relaxed cut, polyester. Order your normal size.
Authentic (Match / Vapor / Heat.RDY / Authentic Pro) — slim athletic cut, lighter fabric, narrow shoulders. Most adults size up one from their replica size. If you wear an EU M in replica, order EU L in authentic.
Nike Dri-FIT ADV / Match — slimmer than adidas, especially in the chest and bicep.
adidas HEAT.RDY Authentic — true to chart, slightly longer in the torso.
Puma Ultraweave — runs small. Always size up.
Castore / Hummel / Kappa retro — boxy old-school cut. Order down one if you want a modern fit.
Boots: round down (boots stretch). Jerseys: round up (shirts shrink slightly after 5–10 washes).
No. Kids' boots use a separate EU 28–38 range. Always measure the foot first; brand listings are inconsistent below age 14.
Most Asian retailers use 0.5 cm increments. If a brand only lists whole-cm, round up.
Most pros wear the authentic in their true chest size. Mbappé's match shirt is an EU M. Haaland wears an EU XL. Don't size up just because they look "loose" — that's a different cut entirely.
