Why are AT boots so much more expensive than alpine boots?

AT boots cost more because they incorporate additional engineering and components: precision-machined tech fittings, robust walk mode mechanisms, lightweight shell materials (Grilamid/Pebax cost more than PU), and often higher-quality heat-moldable liners. The market is also smaller, so R&D and tooling costs are spread over fewer units. Expect to pay $600–900 for quality AT boots versus $400–700 for comparable alpine boots. Think of the premium as the cost of the touring capability that makes backcountry skiing possible.
