How this Adidas → Nike chart actually maps

Adidas US 10 is 27.1 cm; Nike’s nearest US is 10 (EU 43.5). Same centimeter as the reverse page, different EU print: Adidas shows EU 44 at US 10 on the Nike→Adidas table, Nike shows EU 43.5 here. The US numbers still line up 1:1 from 6 (23.5 cm) to 13 (29.7 cm). The wear-box “Adidas 10 ≈ Nike 10.0” is foot-length matching, not a last match.

Read from the Adidas model you actually wear. Samba OG is TTS length with a skinny last — a Samba 10 is not an invitation to take a roomy AF1 at 10. Gazelle’s half-down for narrow/average feet is length, not a Nike-brand rule; Dunk and AJ1 on this site stay TTS. If you already downsize Gazelle and then downsize AF1 because “Nike runs big,” you have stacked two unrelated offsets.

Start at the matched US 10, then open the model guides. Wide feet in Samba who half-up for width should not take that larger number into a Dunk without checking — that is extra length on a TTS Nike last. Half a size here is 26.7 → 27.1 → 27.5 cm. Use it once, for the last that actually needs it.

Model fit matters

Even when charts match, lasts differ. Check these guides:

Adidas: Samba OG · Gazelle · Ultraboost 1.0 · Campus 00s

Nike: Air Force 1 '07 · Dunk Low · Pegasus 41 · Vomero 5

FAQ

How do I convert Adidas shoe size to Nike?
Match by foot length in centimeters on each brand’s chart. Example: Adidas US 10 ≈ Nike US 10.0 (about 27.1 cm). Then adjust for the specific model’s fit (runs big/small/narrow).
Is a Adidas US 10 the same as a Nike US 10?
Not always. Labels can map to slightly different foot lengths. Use the cm column, then check model guides on both brands.
Which direction should I read first?
Start from the brand you already wear, then open the model fit pages linked below — lasts differ even when charts match.

Clothes sizing uses a separate compare path.
