common misconception. Actually, MOST of the shoes from those eras (20's thru early 40's) were made in more narrow sizes. People had more narrow feet... and fit was KING here. Today, even at high end shoe stores, many people will measure foot size by length... but skip the width altogether. I was in Nordstrom and the salesman didn't even know how to work the width measurement on a brannock!
interesting, as our waistlines have expanded so too go the feet!
