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.

Cádomotus Rookie Resizer Insoles | Adjustable Boot-Sizing Solution for Growing Athletes
Are you tired of buying new high-end sports shoes every season as your child grows? The Cádomotus Rookie Resizer Insoles are the ultimate solution! Designed for inline skates, long-track & short-track speed skates, cycling shoes, and ski boots, these innovative insoles extend the lifespan of your child’s performance footwear—saving you money without compromising on fit or comfort.
Extend the Life of Growing Feet’s Shoes
Cádomotus understands the frustration of constantly replacing expensive cycling and skating shoes. That’s why we developed Resizer Insoles—a smart, adjustable insole system that allows one pair of shoes to accommodate three different sizes while maintaining a snug, high-performance fit.
Perfect Fit, Maximum Performance
Unlike standard insoles that shift and slip, our 3D-designed Resizer Insoles integrate seamlessly into hard-sole sports shoes for superior stability and comfort. Engineered with young riders and skaters in mind, these insoles:
- Ensure a tight, blister-free fit to prevent discomfort
- Provide optimal power transfer for skating, cycling, and skiing
- Feature a smooth transition from sole to shoe liner for enhanced comfort
- Maintain shoe stability to keep young athletes performing at their best
Easy & Quick Size Adjustments
With no screws or extra parts required, adjusting the shoe size is effortless. Each size reduction removes 6.66mm from the footbed, allowing for precise, incremental adjustments. When the fit becomes too snug, simply Resize and continue using the same high-performance shoes.
Available Sizes:
- Size 34: Fits foot sizes 32, 33, 34
- Size 37: Fits foot sizes 35, 36, 37
- Size 40: Fits foot sizes 38, 39, 40
