Buster Keaton's Shoe Size
These measurements are based on Buster Keaton's height being 5'6" tall as reported by the "Damfino's" and Buster's Widow. There are other reports of his height being 6'5" which would make his foot approximately 9" by the scale of these photographs. We also have the report below from the California Military Museum.
   
"My pants were too long, my coast looked like a sack, and wrapping Army puttees around my legs was a trick I never mastered. The size eight shoes handed me were far too big for my size 6 1/2 feet. Old-timers in our outfit had long given up hope of ever getting uniforms that fit them. They had theirs altered at civilian tailor shops."
