I agree about finding it interesting to wonder how people did things before.
I remember going to the Bata Shoe Museum in Toronto a few years ago.
They have an online exhibition too.

One of the things I thought odd was some of the earlier shoes were not made right or left foot. they were made with straight soles and square cut toes so they could be worn on either foot.
