No shoes on laminate seems odd, but I did ask viewers to remove their shoes in the houses I've sold in the past as we had pale carpets. I'm not remotely embarrassed about that. Reasoning behind it being
a) it is still my house and I would be the one who had to clean up any mank that came off shoes.
b) I'm assuming whoever bought the house would also not want endless skanky shoe prints in the carpets of their new house.
I always offered to take my shoes off at viewings, it never bothered me in the slightest.
