Bootfitting: Sidas Insoles for Ski Touring Boots

Bootfitting means adapting the inside of a ski touring or alpine ski boot to the shape of your own foot. In the bootfitting category at Šport 11 you will find the products for that job – above all anatomical insoles that replace the thin flat footbeds supplied with the boot. It is aimed at ski tourers, freeriders and piste skiers dealing with pressure points, cold feet or heel lift.

What this category covers

• Insoles Sidas – anatomical footbeds for ski and touring boots that support the arch, stabilise the heel and spread pressure evenly across the whole sole. They go in instead of the stock footbed and help with foot pain, burning under the forefoot and the feeling that the foot is floating inside the liner.

An insole is the simplest and quickest bootfitting step: it leaves the shell untouched, yet noticeably changes how your foot sits in the boot and how power reaches the ski.

How to choose ski boot insoles

• Size and trimming – choose by your shoe size, then trim the insole to the outline of the original footbed taken out of the boot if needed. It must lie flat on the bottom of the liner, without curling up at the toes.
• Arch height – flat, medium and high arches need different amounts of support. Too much support creates pressure, too little does not solve anything.
• Thickness and volume – tight, low-volume touring boots usually call for thinner insoles; in a boot with spare room a thicker insole fills the extra volume and reduces heel lift.
• Intended use – ski touring means long ascents, so support through the stride and moisture management matter most; for freeride and piste skiing the priority is precise power transfer to the edge.
• Materials and warmth – a moisture-wicking top layer and a base that does not soak up water keep the foot dry, and therefore warmer, all day.
• Socks – try new insoles with the ski socks you actually wear, because sock thickness changes the volume inside the boot.

Frequently asked questions

Why replace the stock footbed in a ski boot?

Stock footbeds are usually thin, flat foam with no arch support. An anatomical insole holds the foot in a stable position, reduces heel movement and point pressure, and improves the feeling of control over the ski.

Do insoles help with pain and pressure points in ski boots?

Often yes, because pressure is spread over a larger area and the foot stops splaying and sliding inside the liner. If the pressure comes from the shape of the shell itself or from a bony prominence, the insole needs to be combined with professional shell or liner fitting.

How do I pick the right insole size?

Choose the size that matches your shoe size, then take the original footbed out of the boot and trim the new insole to that outline if it is longer or wider. Trim in small steps and check the fit inside the liner as you go.

Can I use the same insoles in touring and alpine boots?

You can move an insole between boots of similar size and volume, but if you use both pairs regularly it is more practical to keep a dedicated insole in each boot.

How should I look after my insoles?

Take the insoles out of the liner after skiing and let them dry at room temperature, away from radiators and direct heat sources. That way they keep their shape and last longer.
