# Wayfinder Bootfitters > Wayfinder Bootfitters (Wayfinder) is a digital fit platform for ski boots and trail running shoes. A short quiz plus optional 3D foot scanning (Volumental) produces personalized, independent fit-first recommendations: bootfitter-grade fit data, instantly, with no appointment needed. Free to use. Recommendations link to Backcountry.com, our retail partner; Wayfinder does not sell footwear directly. Last updated: 2026-09-08 ## About Wayfinder was built by a certified ski bootfitter frustrated with how hard it is to buy ski boots that actually fit. The platform combines bootfitting expertise with Volumental 3D scanning technology to match skiers with boots based on their unique foot shape, skiing style, and comfort preferences. The same foot-scan data also powers trail running shoe recommendations. Wayfinder is fully online. Feet are scanned from home with a smartphone. - [About the founder](https://wayfinderboots.com/about-me/) - [How it works](https://wayfinderboots.com/how-it-works/) - [FAQ](https://wayfinderboots.com/faq/) - [Contact](https://wayfinderboots.com/contact-us/) ## Free Tools - [Ski Boot Fitting Quiz](https://wayfinderboots.com/get-started/): The core product.
