Match sizes by foot length (cm), then check model fit — US labels alone can mislead across brands.

Nike US 10 is 27.1 cm and Jordan’s nearest US is also 10 (EU 44). The US ladder is 1:1 from 6 (23.5 cm) to 13 (29.7 cm). EU print still differs: this table gives Jordan EU 44 at US 10; the reverse Jordan→Nike table gives Nike EU 43.5 at the same centimeter. The wear-box “Nike 10 ≈ Jordan 10.0” is cm matching inside one corporate family — not “AF1 equals AJ1.”
Model pages on this site split that family. Air Force 1 '07 often runs long (half down unless wide). Dunk Low and Air Jordan 1 High are TTS length references; AJ1’s wear-box maps AF1 US 10 to AJ1 10.5. If you already half-down in AF1 and then take that 9.5 into AJ1 because this brand chart is 1:1, you undersize the Jordan. Convert from Dunk/AJ1 or from 27.1 cm.
AJ4 is TTS in length with a narrower metatarsal than AJ1 — a width change, not a chart change. High/Mid/Low AJ1 share a last for length. Half a size here is 26.7 → 27.1 → 27.5 cm. Use it for AF1’s length habit or for AJ1 width preference, not both stacked on the same pair.
Even when charts match, lasts differ. Check these guides:
