halacha - Status of feet while making a bracha or davening

In todays day and age where we no longer have homes with dirt floors:

• do you still need to cover your feet when making a bracha or davening?


• If so are socks enough?


• does it depend on the custom of the place you live?


• If not would that only apply to carpeted areas?


• is there a difference between being in a private home versus a public area?
