Liner
The inner boot component providing fit, cushioning and insulation.
GLOSSARY · Equipment, setup & maintenance
The liner is the soft inner boot inside the hard outer shell. It gives cushioning and warmth and, on heat-mouldable liners, can be shaped to the rider's foot for a better fit and heel hold.
Context and distinction
The liner is the inner part; the shell is the outer part of the boot. Both affect fit and support.
