It's not always easy to interpret three dimensional shapes in two dimensional photographs but above is a side by side comparison of a W. S. Foster hand made shoe (on the left) and a high quality machine-made shoe. Though each shoe fits the same foot, it's obvious that the hand made shoe is narrower and follows the shape of the foot more closely.
Today's machines just can't make shoes that follow the curves of the feet as well as a person with hand tools and I think it likely that leather shoes will disappear altogether before they do (it's telling that Gaziano & Girling obtained its best-in-category shape on its machine-made offerings not with modern technology but with a century-old machine they located).
The differences in shape are more apparent from the bottom. The machine-made shoe on the left is wider from toe to heel and particularly at the waist, and the upper of course just follows along.
