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.
➤ Choose a size that’s at least 3–5 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

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.

AERO TRIATHLON SHOES WITH WIDE-FIT 4E DESIGN — LONG-DISTANCE COMFORT

The Cadomotus Chronos 4E are aero triathlon shoes that combine the aerodynamic exterior of the flagship Chronos Aero with a flat carbon sole and wide-fit 4E design. At €199, they bring the aero advantage and long-distance comfort for athletes who need a more accommodating fit than a traditional shell sole.

AERODYNAMIC DESIGN WITHOUT THE SHELL SOLE

Inspired by the Chronos Aero’s wind-tunnel-tested profile — 3–9 watt aerodynamic saving measured at Eddy Merckx Velodrome — the Chronos 4E maintains the same streamlined upper and sculpted closure. A flat carbon sole accommodates narrow and wide feet alike. Enhanced ventilation keeps feet cooler in hot race conditions.

BUILT FOR LONG DISTANCE: The flat carbon sole optimises power transfer across the full foot width. Heat-moldable design eliminates pressure points that build up over 90–180km. Sockless fit from T1 to T2 — without the fit restrictions of a high-wall carbon shell.

  • Aerodynamic upper: Streamlined profile based on Chronos Aero wind-tunnel design
  • Flat carbon sole: Stiff power transfer for a wider range of foot types
  • Enhanced ventilation: Improved airflow — optimal in hot race conditions
  • 4E wide-fit design: Roomier fit for narrow and wide feet alike
  • Heat-moldable: Custom fit for sockless long-distance comfort
