When entering the house of your host, or even your own home, be gentle in your manner of entering and leaving. Lower your eyes and your voice. You should take off your shoes at an appropriate spot and set them in an orderly fashion. Do not forget the etiquette of wearing and removing shoes. Put on the right shoes first and remove the left one first,
Rasulullah [Sallallahu álayhi wa sallam] said, “When you put on your shoes, begin with the right and when removing them begin with the left, so that the right shoe be the first to be put on and the last to be taken off.” [Sahih Muslim]
Before entering your house or that of your brothers, inspect your shoes. If they are dirty, remove the dirt or wipe the shoes against the ground. Islam is a religion of cleaniness and courtesy.
