Jordan US 10 is 27.1 cm; Nike’s nearest US is 10 (EU 43.5). Same centimeter as the reverse page; Nike prints EU 43.5 here while the Nike→Jordan table prints Jordan EU 44 at US 10. The US ladder is still 1:1 from 6 (23.5 cm) to 13 (29.7 cm). The wear-box “Jordan 10 ≈ Nike 10.0” is length matching inside the family, not a last match.
Start from the Jordan you own. AJ1 High is TTS — a Jordan 10 should land on Dunk 10, not on an AF1 10 that many people already half-down. AJ4 is TTS in length with a narrower metatarsal; that is width, so do not add a second half on the Nike side just because AJ4 felt snug. If you half-up in AJ1 for width, that larger number is extra length in a Dunk.
Do not apply AF1’s half-down to the Nike column when you are coming from AJ1. The AF1 habit is why this site’s AJ1 wear-box maps AF1 10 to AJ1 10.5 — the opposite direction from this page. Half a size here is 26.7 → 27.1 → 27.5 cm. Use it once.
Even when charts match, lasts differ. Check these guides:
