How to tell if shoes are hand-made

The following was posted on the Shoemaking Forum Facebook page:

I have a wonderful story for you. One guy ordered Lobb’s shoes from time to time and he only wanted one certain maker to make them. Once when he was ordering a new pair, the maker was on vacation (a old man on his 70′ s). So another person made his shoes and he said that he didn’t want them..they are too perfect. “I like the shoes made by the guy whose eyesight is not good anymore and little mistakes pop up.. because for me then I know they are truly handmade.”
