FitVault

FitVault is a mobile + web AI app that reduces luxury shoe returns by making sizing and fit more predictable across brands and lasts. Users scan their feet with a phone camera, then log how specific shoes actually fit (heel slip, toe room, arch pressure) after real wear. The app converts that into a personal “fit fingerprint” and recommends the best size for a given model, not just the brand. For boutiques and resale sellers, FitVault offers a lightweight portal to attach verified fit guidance to listings and in-store QR codes, lowering return rates and boosting buyer confidence. This is not a generic size chart: it’s model-level fit intelligence built from scans + structured feedback. Monetization: consumer premium for advanced recommendations and history, plus B2B subscriptions for boutiques/resellers to reduce costly returns and customer service time.
