I have always thought that one makes Salat without shoes on, but there is the following Hadith which says:
خَالِفُوا الْيَهُودَ فَإِنَّهُمْ لاَ يُصَلُّونَ فِي نِعَالِهِمْ وَلاَ خِفَافِهِمْ
Act differently from the Jews, for they do not pray in their sandals or their shoes
So my question is, according to authentic sources, should one pray with ones shoes on or off?
