No.
Many studies have shown there is no evidence to this widely held belief. It is one the most striking cultural beliefs not based on facts.
Researchers at University College London added to the growing studies finding no evidence linking a man’s shoe size with the length of his penis.

ABSTRACT
Objective To establish if the ‘myth’ about whether the size of a man’s penis can be estimated from his shoe size has any basis, infact.
Subjects and methods Two urologists measured the stretched penile length of 104 men in a prospective study and related this to their shoe size.
Results 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.
Conclusion The supposed association of penile length and shoe size has no scientific basis.
