Fastest path: open any shoe model or clothes line page and use the on-page fit survey (“What size did you take?”). Submissions are anonymous, rate-limited, and stored privately. We do not publish percentages or response counts until a page reaches 25 real responses — no fake “n=” bars.
Prefer email? This form opens your mail app with a prefilled message to hello@whatsizetobuy.com.
We do not publish your name, email, or photo on the site. Replies are for editorial review only. We never invent “47 people said…” stats from a handful of notes.
How we use replies: survey aggregates may inform future summary or confidence updates after we cross-check sources (see methodology and fit diary). One response alone never flips a row to Verified. Owner paste log: repo feedback_log.md.
Model and clothes line pages POST to /api/fit-survey.php (honeypot + rate limit).
Email above remains the long-form / sources path.
