I wear slippers in winter, to keep warm, and Jandals in summer, I am not keen on barefeet anywhere,think about it, people may have smelly sweaty socks, then take them off and walk around,not only leaving a not so nice aroma, but you never know where they have been with those feet, it might be best if guests keep their shoes on, but then you don't know where they have been either, maybe we should offer our guest throw away slippers he he.. but yes I wear different shoes for outside most of the time, now trying to get the rest of the family to obey my rules is another story.
