A 1983 study of 4,000 women and 2,800 men across the U.S. found that none of them had a pair of feet that were exactly alike in size or shape.

A 2018 study found that 19% of people in the UK have feet that differ in length by about one-sixth of an inch ( 4 millimeters ) A number of birth conditions can lead to one foot being a significantly different size than the other.
