Growing up, we never really got in the habit of taking our shoes off when we came in from outside. Moving to Texas, we realized EVERYONE takes their shoes off to come inside. After all the rain and mud I saw here in Houston, I understood the reasoning for this better. In fact, I have one night we had been invited to a friends house. As we were driving over there I was painting my toe nails and my husband asked what I was doing. I told him I wanted to make sure my toes looked cute since I knew we’d have to take off our shoes. He had forgotten this (since we were still pretty new to Texas) and went on to tell me that he happened to be wearing the pair of socks that had the most amount of holes! We laughed, and I reminded him we were no longer in AZ. LOL!
Another person who says removing shoes in homes is common in Texas, contrary to the common view that nobody in Texas takes their shoes off. Most of the shoe-removing Texans seem to be in Houston, which is of course, a very modern and diverse city.
