For the most accurate measurement:
Measure your feet at the end of the day, when they may be slightly swollen.
Stand while measuring, so your foot is fully weight-bearing.
Measure both feet, as one foot can be slightly longer than the other.
Record the length of your larger foot in millimetres.
Compare the measurement with the UDOG size chart.

UDOG shoes are designed with a slightly wider fit than many european cycling shoe brands, with generous space in the toe area.
The shape is designed to allow the toes to move naturally while keeping the foot securely supported during the pedal stroke.
A cycling shoe should feel secure without creating excessive pressure.
Your heel and midfoot should remain firmly supported, while your toes should have enough room to move naturally. The shoe should feel snug and supportive rather than tight or restrictive.
You do not need to over-tighten UDOG shoes.
The closure system and Tension Wrap System™ are designed to distribute tension across the foot, creating a secure and supportive fit without relying on excessive pressure from the top.
Start with a comfortable level of tension and adjust it gradually while riding or next ride.
The Tension Wrap System™ is UDOG's patented fit technology. It wraps and supports the foot from the bottom up, distributing tension around the metatarsal area for a secure and comfortable fit.
TWS is designed to provide support throughout the pedal stroke while helping reduce concentrated pressure points.
Yes. While UDOG follows a consistent sizing system across the collection, different models have different constructions, materials, closure systems and discipline.
For example, performance-oriented models such as Cento made in microfiber upper have a more structured, locked-in feel, while gravel models such as Forza using mesh material combine a secure fit with a generous toe box designed for longer days and mixed terrain.
