How this Nike → New Balance chart actually maps

Nike US 10 is 27.1 cm and the nearest New Balance US is 10 (EU 44). The table is 1:1 from US 6 (23.5 cm) to US 13 (29.7 cm). The wear-box “Nike 10 ≈ New Balance 10.0” is that centimeter — it does not say Dunk and 990v6 share a last. New Balance’s own chart on sibling pages sits a hair differently in the JSON (US 10 ≈ 27.2 cm); this printed match still lands on NB 10.

Width is the real fork. 574 and 990v6 publish D / 2E / 4E. Many 2002R and 550 colorways are D-only. A chart-matched Nike 10 in a tapered Dunk can still pinch in a D-width 550 and feel loose in a 990v6 2E. AF1’s half-down habit is a Nike lifestyle quirk; do not carry that smaller number into a 2E 990 and then wonder why the heel slips.

Start at US 10 in length. Spend the decision on the letter, not on jumping to 10.5 unless the specific NB model runs long. Half a size here is 26.7 → 27.1 → 27.5 cm (~4 mm). That tweaks length. It is not a substitute for 2E. Convert from Dunk/AJ1 TTS, or from 27.1 cm, not from an AF1 that you already sized down.

FAQ

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