Chronos/Worldcup CarbonShell™ cycling shoe size chart

Chronos/Worldcup CarbonShell™ cycling shoe last size

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 shoe 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.
➤ 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

Special Fit Cases

  • Narrow or wide feet?
    If you’re in Bracket 1 or 5 for width, we recommend a custom width.
    ✔️ Wide versions of all CarbonShell™ shoes are available on request, with an 8-week lead time and a surcharge.
    ✖️ Narrow versions are not available—size down or mold for best fit.

  • Low instep?
    A low instep may feel loose or unsupported. This is common among elite triathletes 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. Riders 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 (Bracket 4), you can also try sizing up one size for more space.

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