The Goq: “one should not be barefoot in the kitchen you might slip on some schmaltz.”
Also, some would say it’s untznius. I know it depends on minhag hamakom, but it’s hard to imagine that there are too many Frum Jews who feel that women’s job is to be barefoot and pregnant in the kitchen yet consider it okay for women to walk around without socks. T/f, acc. to the rules of logic, one would have to conclude that there are very few Frum Jews who feel that women should be barefoot and pregnant in the kitchen.
