Why ski insoles are essential
Rigid ski boots, demanding positions, cold temperatures, pressure concentrated on the front or heel: skiing puts a very different strain on the feet than walking or running. The result: excessive pressure, pressure points, loss of blood circulation, cold, discomfort and early fatigue. Insoles designed for skiing transform the experience: they put the foot in the correct position, distribute pressure, maintain warmth and reduce pressure points — for longer, more comfortable and more enjoyable days on the slopes.
What Sidas technology offers
- Anatomical support + heel support — Sidas ski insoles, such as the 3Feet® or 3D range, feature an ergonomic shell and heel + arch support. This ensures good stability in the boot, optimal foot alignment and reduced micro-movements.
- Even pressure distribution & shock absorption — EVA foam, 3D structures and thermoformable shapes distribute pressure across the entire surface of the foot, cushioning impacts and limiting sensitive areas (forefoot, heel).
- Thermal insulation & long-lasting comfort — Several insoles incorporate insulating materials (aluminium film, insulating foams, specific coatings), which help keep feet warm while maintaining breathability and comfort.
-
Optimised energy and performance — Good foot-insole-boot contact improves the transmission of pressure to the skis, facilitating transitions, turns and overall control. This results in greater precision, more responsiveness and less wasted energy.
Who are our ski insoles for?
- Regular or intensive skiers looking for comfort and performance throughout the day.
- Those who spend a lot of time in boots — touring, freeriding, downhill skiing, recreational skiing.
- People who are sensitive to the cold or have fragile feet (poor circulation, pressure points, blisters, frostbite, etc.).
- Those who want to improve their posture and alignment to avoid fatigue, pain or discomfort.
- For demanding skiers who want precision, stability and control — carving, turning, weight transfer.
Expert foot advice & best practices
- Choose the right insole for your arch — Use a model that suits your foot type (flat feet, normal arch, high arch). An unsuitable arch reduces the effectiveness of the support, can create pressure points or reduce comfort.
- Adapt the insole to the boot — Cut the insole to the right size if necessary. Replace the original insole with the Sidas insole, without stacking several insoles.
-
Take good care of the insole — Clean with a brush and mild soap — avoid using a boot dryer or radiator. This will extend its life and preserve its insulating properties.
- Combine the insole with a suitable sock — To optimise comfort and warmth, especially in cold or wet conditions.
- Test gradually— Over half a day or a weekend to check the fit before setting off on long days.
FAQ (frequently asked questions)
Why do my ski boots hurt even though they are properly adjusted?
Because the original insoles are often neutral, uncompensated and poorly adapted to the arch of the foot. The foot becomes deformed, pressure builds up, causing pain, numbness or hot spots.
Can any insoles be used in ski boots?
No — you need specific insoles for ski/rigid boots, with heel support, arch support, suitable cushioning and thermal insulation. ‘City’ or ‘running’ insoles are generally not suitable.
Should I always replace the original insoles?
If you ski for more than one day, use your boots regularly, or are looking to improve comfort/performance — yes, it is highly recommended.
How do I know which insole height to choose (low, mid, high)?
By observing your foot (visible arch or not), or better still, by having a foot analysis (footprint, scan, podoscope). Alternatively, try out different insoles to determine which one provides the best comfort and support.
