You may have noticed that retail staff often remove their shoes before setting up displays in shop windows.
The managers of their shops obviously fear the appearance of scuff marks on the shiny window ledges.
If you have a wood or vinyl floor, do you care about it as much as the managers of these shops care about the window ledges of their shops? Shoes can so easily cause scratches or leave marks on your floor. Especially if people get stones or other sharp stuff stuck on the sole.
