Ci1 Pro boot last — How to Choose Your Size

Scan Your Feet
Follow the steps in the app. You’ll receive a detailed 3D profile of both feet.

Ask our CádoWiki Live: Instant Expert (in the bottom-right corner) for your best shoe size, or:

Use the Cádomotus Size Chart
Our chart shows the length of the last—the mold your boot is built on—not the length of your foot. One last length fits a range of foot lengths, so look up your measured foot length in the Fits foot length column and read off your size.
➤ Skate boots are fitted closer than shoes: we allow 2–3 mm of room, not more. A snug boot gives control and power transfer.
➤ On the edge between two sizes? Your width and instep bracket decide: wider or higher volume → take the larger size.

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.
