How to Choose Your Size
Scan Your Feet
Follow the steps in the app. You’ll receive a detailed 3D profile of both feet.
Use the Cádomotus Size Chart
Our chart shows the length of the last—the mold your shoe is built on—not the length of your foot.
➤ Choose a size that’s at least 2–4 mm longer than your longest foot for a snug, race-optimized fit.

Understand Width and Instep Height (1–5 Scale)
The app shows both measurements on a 1–5 scale:
- 3 = average → standard fit
- 2 or 4 = slightly narrow/wide or low/high → ideal for heat molding to fine-tune the fit (visit one of our dealers to get support if you are unsure about doing it by yourself)
- 1 or 5 = very narrow/wide or very low/high → see options below
Special Fit Cases
-
Narrow or wide feet?
If you’re in scale 1 or 5 for width, we recommend a custom boot. -
Low instep?
A low instep may feel loose or unsupported. This is common among elite skaters who often use orthopedic insoles for volume control and support.
✔️ We recommend using performance insoles to optimize fit. -
High instep?
We do not offer high-volume shoes. Skaters with a high instep should use heat molding and fine-tune strap tension for comfort and circulation.
Wide Foot Tip
If you're borderline wide (scale 4), you can try sizing up one size for more space, or visit one of our speed skating specialist dealers to have the boots heat molded.
Pro Tips for Ice Speedskate Fit
-
Race Fit vs. Comfort Fit
Race skaters choose the smallest possible size for maximum power transfer and control. For longer training sessions or marathon use, you may prefer one size up for extra comfort. -
Sock Thickness
Always measure and fit with the socks you’ll use in training or racing. Thin technical socks are standard; thicker socks can alter fit and circulation. -
Heat Molding Reminder
All Cádomotus boots are heat-moldable. Even average-fit feet benefit, especially around heel and ankle.
Guide: 80 °C for 15 minutes in a standard oven (consult dealer instructions). -
Heel Fit
A snug heel lock is essential for control. Before molding, some heel lift is normal. During heat molding, focus on shaping the heel pocket so the carbon clamps your heel between the ankle bones. This locks the heel in place. If you still feel movement after molding, repeat the process with more pressure on the heel area, or have a dealer spot-mold it for you. -
Ankle Bone Sensitivity
Prominent ankle bones can press against the carbon. Heat molding or dealer spot-punching resolves this. -
Toe Box Feel
Toes should lightly touch the front when standing upright, but not jam when you bend into skating stance. This snug feel is very different from running shoes. -
Asymmetry
Always size for your longest foot. The shorter foot can be shimmed with insoles or volume pads.
Following these guidelines ensures a snug yet comfortable fit for optimal performance.
