What to write about
- Fit-data corrections — wrong verdict, outdated chart, or width note that no longer matches retail guidance.
- Source tips — official brand size charts, retailer fit notes, or consistent multi-source review patterns.
- Site bugs — broken converter links, 404s, or display issues on mobile.
- Partnership / affiliate questions — including Amazon Associate disclosures.
How to send a useful correction
Please include:
- The page URL (example:
/nike/dunk-low/).
- What you think is wrong (length, width, badge, converter bridge).
- Links to sources (brand chart, retailer fit guide, or other primary references).
- Your usual size in a reference shoe (optional but helpful).
We prioritize sourced corrections over single unverified opinions. Not every email changes a Verified row — conflicting signals may keep a Partial badge on purpose. See methodology.
Faster path for fit feedback
Fit feedback opens a prefilled email template if you want a shorter path.
Response expectations
We read every message. Simple bug reports are usually acknowledged faster than deep fit disputes that need a source re-check. If you do not see a public page change, the badge or verdict may still be under review.
