BS”D
Not wearing socks or hose in public is grub and prust, plain and simple (sorry, Ames and Shaatra, I’m working on 10 different things right now and can’t come up with how to say that in any language except Yiddish…maybe uncouth but that does not convey the same meaning). And in the case of women who spend money so that they can show off their pedicured feet in open shoes, it is hepech everything tznius and Yiddishkeit are all about even if there is some way of allowing it al pi baseline halacha.
That applies for men and women except in certain situations such as some sports or the beach perhaps. Taking out the garbage or running a quick local errand in house shoes with no socks is understandable and if this is mutar then so be it, but presenting yourself that way in general is not what we should be striving for even if there is a way around it.
Regardless of the technicalities of any particular halacha or minhag, do we want to be grub and prust?
