This kind of massages is quite normal for the older crowd I think, my grandparents used to have a guy go over to their house daily. He was blind and worked on them in their bed.
if your feet are blistering a lot, then it’s possible your sock+shoe combination don’t quite work for your feet. have you ever gotten your feet properly measured?
