Insoles are a simple way to refine how ski boots feel and perform. Within this category you will find options designed to stabilize the foot, improve alignment and add insulation, so the shell and liner can do their job more effectively.

Support and control: A defined arch shape and supportive heel cup help reduce foot collapse, keep the knee tracking straighter and hold the heel down for precise edging. Choose between low, medium and high arch profiles to match your foot.

Warmth and moisture: Topsheets in merino wool blends, insulating foils and breathable foams help retain heat and manage sweat. This can reduce cold spots and odor build-up on long days in the snow.

Cushioning and vibration damping: Multi-density EVA, PU or gel layers spread pressure and absorb chatter. This can ease pressure points, reduce fatigue and make the boot interior feel more even without masking snow feel.

Volume tuning and fit: Insoles are available in low-profile and higher-volume constructions to fine-tune space in the shell. Trim-to-fit models can be cut to size; heat-moldable versions adapt to the foot for a closer interface.

How to choose: Start with arch height and foot width, then consider boot volume. If the boot feels roomy, look at firmer or thicker insoles; for tight boots, pick a thinner, low-profile design. Match size to the ski boot’s mondo size and trim carefully at the toe if needed. Test with your usual ski socks.

Compatibility: These insoles work in most alpine and touring ski boots. They also pair well with custom liners and can be used with boot warmers if the thickness allows. Avoid stacking multiple insoles.

Care and lifespan: Remove insoles after skiing to air-dry, avoid direct heaters, and brush off lint or snow. Replace when the foam stays compressed, the heel cup loses shape or the top cover peels.
