Can shoe size predict penile length? Context: To establish if the 'myth' about whether the size of a man's penis can be estimated from his shoe size has any basis, in fact. Two urologists measured the stretched penile length of 104 men in a prospective study and related this to their shoe size. The median stretched penile length for the sampled population was 13 cm and the median UK shoe size was 9 (European 43). There was no statistically significant correlation between shoe size and stretched penile length.

The supposed association of penile length and shoe size has no scientific basis.
