My feet are almost always cold due to neuropathy. Even wear socks to bed. If the A/C is on, definitely socks! Never barefoot, fallen arches makes walking on the floor barefoot painful. Also, I have a knack for injuring my feet. Stubbing a toe breaking it once, twisting my ankle, DH said he would buy me combat boots but he never did so now I blame him saying I got hurt because I don't have those boots.
