Applications & Expertise

Sidas In Detail: Insoles, Boot Fitting, and Maintenance

For five decades, Sidas has been shaping the perfect fit in ski boots. Below, you’ll learn how the brand came to be, which insole and boot-fitting solutions are right for your feet, and how to properly care for your Sidas accessories.

Marke & Herkunft

Sidas Insoles: From a French Foot Comfort Specialist

Sidas The brand was founded in 1975 when three French ski instructors drew inspiration for a ski boot from an observation they made on the beach: A footprint in wet sand supports the arch of the foot more precisely than any mass-produced, one-size-fits-all insole. In Voiron, the founding team developed the first thermoformable insoles and initially molded them in their home ovens—a principle that remains at the core of the brand to this day and has been consistently refined ever since.

At the heart of the design is the patented 3Feet concept: three insole models—Low, Mid, and High—for different arch heights, ensuring that every foot receives the anatomical support it actually needs, rather than a standard shape that requires compromise. For ski boots, where the tight shaft intensifies any pressure points, this custom fit makes a noticeable difference in stability, power transfer, and endurance throughout the entire day of skiing. The Sidas 3 Feet Winter High insole is designed for high arches and can be thermoformed at a specialty retailer or in an oven.

Passform & Boot-Fitting

Sidas Boot Fitting: Tailoring the Ski Boot Specifically to Your Foot

A properly fitted Sidas insole is the foundation, but it’s the boot fitting that turns a ski boot into a second skin. Sidas offers a well-designed system of individually customizable components for this purpose: The Sidas Heel Lifter Hard 4mm raises the heel when there’s too much volume in the boot shell, thereby improving power transfer to the edge, while Volume Reducers specifically reduce lateral width. The Comfort Fit Tongue Evo eliminates pressure points on the instep without restricting the shell’s flexibility and can be retrofitted in just a few minutes.

We also carry Sidas ski socks to meet a variety of needs: the Ski Protect models with shin protection for intense skiing, and the thinner Ski Merino for purists who prioritize minimal bulk. If you need to keep your feet warm even in freezing temperatures, combine the insole and boot fitting with the heated Ski Heat Race Set. We’d be happy to advise you in person at our store on the right combination of insole, fitting element, and sock.

Care & Accessories

Care, drying, and accessories for your Sidas gear

To ensure your insoles and ski boots last for many seasons, drying is an essential part of care: Moisture inside the boot breaks down the cushioning and promotes odor. The Sidas Drywarmer Pro USB actively dries boots and gloves and can be powered on the go via a power bank, while a Cedar Wood Dryer Bag passively absorbs moisture between uses and keeps the shell fresh from the inside.

To prevent friction on the heels and toes, we recommend the “ Sidas ” Anti-Friction Cream, which is applied directly to the skin and helps prevent blisters during long days on the slopes; the “ Sidas ” Foot Care Kit combines the essential care products for on-the-go use. After intense days on the slopes, the Recovery Cryo Gel provides noticeable relief for tired feet. For travel and races, the Sidas Race Boot Bag keeps your boots and accessories protected and within easy reach. We’d be happy to advise you personally on other uses—either in our store or directly through our customer service.

For the perfect fit in your ski boots, take a look at our “Sidas ” insoles, complemented by skin protection products for long, comfortable days on the slopes. If you’re particularly prone to cold feet in the winter, you’ll find the “Sidas ” Volocano H heated insole —a practical, heated option—in our selection.
