Shoe covers are usually a joke because i see guys wearing them out to their truck then back in...But...it gives the client the impression that you care about their home so why not? Comcast guys wear them. The plumber wears them. The high end AV guy should wear them too.
I usually just kick my shoes off at the front door and put them on my moving blanket...even though its the worst thing you can do for your feet and back. At a project in Florida where the house staff was in the double digits they all wore black crocs inside the house. They had a staff mudroom where they would swap out their street shoes for inside shoes. Another installer and I got our own inside shoes...something like these lol
