How to Measure Your Foot
- Place a piece of paper flat against a wall and stand on it with your heel touching the wall.
- Using a pencil or pen, carefully trace around your foot while keeping the pencil upright.
- Measure the distance from the edge of the paper (heel) to the tip of your longest toe.
- Compare your measurement with the size chart above to determine your Shimano shoe size.
Sizing Tip: Shimano cycling shoes are designed to provide a snug, performance-focused fit. If you're between sizes, Shimano recommends choosing the larger size.
