Interesting fact... never was aware about this...
Up to the early 19th century, shoes were absolute ‘straights’ since there was no idea about having a left and right shoe. There were two
widths to choose from: the slim shoe and the fat shoe. So, if one could afford to buy a pair, it was only a matter of finding a way to get used to the new shoes.
The same issue existed in armour as it can be noted from this pair of finely moulded jambes, or greaves, which date to c. 1525. Its various borders are decorated with narrow bands of etched acanthus leaves, all gilded, the remaining surface being russeted.
