Questions.

How accurate is BootFit?

Honest answer: it depends on the evidence. Recommendations built from a boot you already own are the most reliable. Every result carries a confidence tier, and when the evidence is thin we say so instead of guessing. As players log real purchase outcomes, accuracy improves for everyone.

How is this different from a size chart?

A size chart maps your foot to a number. BootFit maps one boot to another: it knows the Ultra 5 runs long, the Predator runs slightly short, and the F50 is too narrow to fix by sizing up. Charts cannot tell you any of that.

Why do you ask about my current boots?

Because a boot you wear every week is the most precise measuring device you own. How it fits in length and width tells us your foot shape better than any self-assessment about arches or toe types.

What if I do not own football boots?

Use Foot Profile mode: two measurements, your everyday sneakers, and three quick questions. It is clearly labeled as lower confidence, and the moment you add a boot that fits, your recommendations upgrade automatically.

Is my data private?

Fit reports are anonymous and only ever used in aggregate to improve sizing recommendations. We never sell personal data.
