Scarpa Pro Flex Liner

No, this specific liner is engineered exclusively for the Fall 2023 Maestrale RS. It will not provide the correct fit or volume for earlier versions of the boot.

While you can technically wear them without molding, heat-molding is highly recommended. It activates the Intuition foam to conform to your specific foot shape, which is essential for achieving the intended comfort and power transfer.

These are designed as a direct replacement for specific Scarpa models. Using them in other brands often results in a poor fit, as the internal volume and cuff alignment are calibrated specifically for the Maestrale RS shell.

This is the exact same liner that originally shipped with the Fall 2023 Maestrale RS. It is intended to restore the original performance and snug fit of your boots once your current liners have packed out.

We strongly recommend having these molded by a professional boot fitter. They have the specialized equipment and experience to ensure the foam expands correctly without damaging the liner or creating pressure points.
