Shabbos shoes themselves are not a big issue, nor are paper plates or walking around in socks, what is a VERY BIG ISSUE, is that mrs. katz has had a VERY TRYING yom tov, with a mother in law who does not know limits.
?? ???? ??? ????? but say your kids live in eretz yisroel, and seemingly pople there do not have shabbos sheosm your children will probably not wnat to be the rich americans on the block with shabbos shoes. when i grew up no one had shabbos sheos, and perhaps in soem places parents consider it to be spoiling their chidlren, etc..
