Data versions
Size labels and measured foot length are different quantities. A chart does not establish the fit of every model. There is no verified brand-wide fit offset or reproducible wearer distribution in this dataset.
“Source checked” records when the cited page was read. “Editorial review” records a change to our explanation. Neither is reset during a build, and no automatic monthly verification schedule is claimed.

Added the separately reviewed US Nike women's chart: 39 label rows, 28 explicit foot-length rows and 11 unknown foot lengths retained. Published youth cross-labels cover 2Y–7Y only. Added the official US Hoka regular footwear charts: 21 men's rows and 15 women's rows, with explicit foot length kept separate from Japan CM labels and no model fit correction. Hoka brand/comparison pages retain noindex, and these charts do not release new size pages for search. The newly eligible US women 4 and 4.5 size pages retain noindex pending search review. Reviewed men's Brooks Ghost 18 family 110493 and its US width options; no measured fit correction or wearer consensus. Its model and newly eligible derived pages retain noindex pending separate search evidence. Added scoped multi-brand foot-length lookup and label decoding; neither establishes equivalent fit or a measured correction between models. The 2026-09-05 charts retain their original source-check dates.

Evidence repair: replaced generated brand tables with 10 directly checked manufacturer charts; corrected Converse Chuck Taylor advice; reviewed 10 scoped model guides in 15 locales; removed unsupported aggregate counts, fit offsets and probabilities. Added an explicit noindex review queue and consolidated duplicate comparison URLs. Replaced universal width and kids approximations with scoped New Balance and Nike source rows. JSON schema v2 separates chart labels from measured foot length; missing data is null. This entry records a dataset revision, not a claim that every source or record is verified.
