Okay maybe I don't know what I'm talking about, but with boots, hiking boots, the women's shoe last has a narrower heel. I have been told that male feet are square in footprint and women's feet are more triangular in footprint. The narrow part being the heel.
But anatomical shape doesn't have much to do with the shoes we buy!

Podiatrists claim that almost all women wear shoes that are too small for them, both in width and length. I have definitely fallen into that trap and suffered for it. And am still looking for fat toe box shoes with a narrow heel.
