Irish Shoe Superstition

My informant is of Irish decent, and he told me of an old superstition he learned about shoes in the home. Apparently,  the Irish believe that it is bad luck to put one’s shoes on a table in the house. He has no idea as to the reason for such a superstition, all he knows is that in his house whether you believe it or not you’re afraid to find out if it is true.

The reason for this superstition may be unknown, but there is another version that I have come across on the internet. The other version says that it is bad luck to put one’s shoes on the bed, and the reasoning behind it is that it would bring a death in one’s family.
