Percentile is the share of the group with shorter feet than this size fits. “1 in X” counts the rarer side: people at or beyond this value above the median, at or under it below. The size is converted to foot length in cm, then compared with a normal distribution of foot lengths.
What this means
- The average man's foot is 26.5 cm, about a US men's 10.5. The average woman's is 24.0 cm, about a US women's 8.5. A men's 13 is 2.3 cm longer than the men's mean.
- Measured against women, the same foot is longer than over 99% of them. In US women's sizing it is about 14.
- Stock thins out fast above the mean plus two SDs. Being this rare has a cost, and it is measured in shipping fees.
