Scarpa Cross Fit Tour Liner (Alien RS)

The Scarpa Cross Fit Tour Liner (Alien RS) is a unisex replacement touring boot liner designed for refreshing the fit and insulation of compatible SCARPA Alien RS boots. The Cross Fit Tour construction is shaped for alpine touring, with a low-bulk profile that supports ankle articulation while maintaining a close interface with the shell. Its thermoformable foam can be heat molded by a qualified bootfitter to improve heel hold and reduce localized pressure. This is a replacement liner, so shell generation and size compatibility should be confirmed before fitting. The overall design keeps the product focused on its intended job without adding unnecessary complexity, making it a practical choice for riders or skiers who value reliable function and clean integration with the rest of their kit.
