Customizing your liner to suit fit requirements in the shell.
You can purchase aftermarket liners once your liner reaches the end of its life or sometimes this is necessary to start with so to help with the way your boot fits you or depending on what you will do with your boots in the mountains.
Intuition liners are a great option and come in many styles, shapes and sizes. They can be easily placed in the oven and heated to custom them to you and the boot you put them in. like ski boots they come in narrow LV fits or MV and HV to suit the shell.
Foam Injection liners are a liner with pockets internally where expanding foam can be injected offering the wearer a snug tight fit, filling up any gaps from you to the liner to the shell. There are two types of these liners with the most common being just the outside walls of the liner receiving foam. The second type is possible to foam the tongue as well as the outside walls with foam.
These are generally a special-order item and some notice and fitting time is required to complete this type of requested fit. These also come in many shapes and styles.
