Let’s say your left foot is 26.3 centimeters and your right is 26.5. For shoes that need a snug fit and/or will likely stretch out, look for the size that corresponds to 26.5 or 27 centimeters.

In contrast, the 2018 study found that the right foot was usually the longer one, with 50.7% of U.K. women, and 54.8% of U.K. men, having their right foot longer than their left.
