Orthotic insoles for your ski boots

Functional insoles, also known as footbeds, inserts or orthotics form the intelligent interface between your foot and the boot. Invest in this accessory and enjoy the following benefits:

• Optimised power transfer: An insole for your ski boot improves the direct power transfer from your foot to the ski. The ergonomic shape ensures that your movements are transferred to the edges more precisely and efficiently.
• Better pressure distribution: Orthotic insoles distribute body weight evenly across the entire sole of the foot. This prevents pressure points that can lead to pain or fatigue.
• Increased stability: The 3D construction of a high-quality insole stabilises the arch of the foot and prevents uncontrolled movements in the boot.

As every foot is different, the standard insoles which are provided may not fit your individual shape. The answer to this question is therefore quite simple: in principle, all skiers can benefit from functional insoles!

• For the majority of skiers, the foot stretches when rolling, causing the toes to hit the front of the boot. A functional insole can stabilise and support the foot to prevent this.
• For skiers with inflexible feet, insoles can help distribute body weight more evenly across the foot, resulting in better control and less fatigue.
• Even if your feet have sufficient stability and flexibility, you could still benefit from functional insoles – increased comfort, more warmth and better performance when skiing.

High-quality insoles, such as those from Sidas, offer a range of benefits that will improve your skiing experience.

• Support the arch of the foot and ensure anatomically correct posture
• Cushion impacts while skiing and protects joints
• Reduce pressure points and muscle pain
• Prevent overheating and fatigue through optimised ventilation

• Improve power transfer to the skis
• Increase precision when turning and changing edges
• Ensure greater stability and control
• Reduce energy loss through better foot positioning

Ski boot insoles provide greater comfort, better support and optimised performance. This means that you tire less quickly. In the long term, there is less strain on the joints.

Choosing the right insoles depends on several factors:

• The shape of the arch (low, medium, high)
• Preferred level of warmth and insulation
• Type of activity (Skiing, Snowboarding, Ski touring, ...)
• Intensity of the activity and your personal riding style
• Individual foot shape and any misalignments

Sidas offers different types of insoles depending on your needs. From heated models to thermoformed insoles for women and men, the different categories meet the needs of a wide range of winter sports enthusiasts.
