Which foot is bigger, left or right?

Published in Foot Anatomy 2 mins read

Generally, the left foot is typically bigger than the right foot for most people.

Why is the Left Foot Often Larger?

This difference in foot size is largely attributed to the way we walk and the body's dominant side. Here's a breakdown:

  • Dominant Side: For most individuals, the right side of the body is dominant. This means we often favor this side in terms of strength and coordination for everyday tasks.
  • Walking Mechanics: The subtle differences in how we walk can have an impact. When walking, the non-dominant foot tends to bear slightly more weight and stress as the dominant foot initiates movement. Over time, this can lead to a slight increase in the size of the left foot.

Foot Size Difference: A General Tendency

While the left foot is typically larger, it's important to note this is a general trend, not a hard rule. There can be cases where:

  • The right foot is larger.
  • Both feet are of equal size.
  • The difference in size is negligible.

Practical Implications

The slight difference in foot size is often not significant enough to cause major issues, but it is useful to consider when purchasing footwear:

  • Shoe Shopping: When trying on shoes, it's recommended to try on footwear for both feet to ensure a comfortable fit. If one foot feels tighter, consider a size that fits the larger foot comfortably.
  • Custom Orthotics: When considering custom orthotics, it is advisable to take measurements of both feet as they may require different configurations.
