How this Adidas → New Balance chart actually maps

On this page Adidas US 10 is 27.1 cm and the nearest New Balance US is also 10 (EU 44). The printed ladder is 1:1 from US 6 (23.5 cm) through US 13 (29.7 cm). The wear-box “Adidas 10 ≈ New Balance 10.0” is that centimeter match — it does not say Samba and 990v6 share a last.

Adidas terrace shoes on this site split by width more than by length: Samba OG is TTS length but narrow; Gazelle often feels a half long for narrow/average feet; Campus 00s and Ultraboost 1.0 follow their own volume. New Balance is the opposite toolkit: 574 and 990v6 publish D / 2E / 4E, while many 2002R and 550 colorways are D-only. A chart-matched US 10 in Samba can still pinch where a 990v6 US 10 in 2E feels loose.

Use the cm column as a starting ticket, then pick the model. If you wear Adidas Originals US 10, try NB 10 in length and spend the decision on width letters rather than jumping to 10.5. If you already size Gazelle down a half, do not automatically downsize a 574 — Gazelle’s length-down is a terrace quirk, not a brand-wide Adidas rule. Half a size on this table is ~4 mm (26.7 → 27.1 → 27.5 cm). That is a length tweak, not a substitute for 2E.

FAQ

How do I convert Adidas shoe size to New Balance?
Match by foot length in centimeters on each brand’s chart. Example: Adidas US 10 ≈ New Balance 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 New Balance 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.
