So I've heard that we Jews (when waking up) used to first wash their feet and then their hands. But what happen today, don't we wash our feet anymore? Or is that an optional thing? Do some still do it today?
The Gemara (Shabbos 50B) says one should wash his face, hands and legs every day in honor of his Creator.
The Mishna Berura (OC 4:2) writes in the name of the Pri Megadim (A"A 4:1) that nowadays since we don't walk barefoot there is no need to wash one's feet (This reasoning is also given by the Noda Biyhudah (OC 2:140)), although the Baal HaTanya (OC 4:21) brings this gemara with no comment.
