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
• 1 or 5 = very narrow/wide or very low/high → see options below

Wide Foot Tip
If you're borderline wide (scale 4), you can also try sizing up one size for more space.

Following these guidelines ensures a snug yet comfortable fit for optimal performance.
