When it's cold I wear socks (usually more than one pair). In the heat of the summer I'm barefoot. I never wear shoes inside our house. DH always wears slippers and DD would go barefoot all the time if I let her.
Another socks when cold, but other than that barefoot. I hate wearing shoes in the house and I have passed that on to my oldest DD. She walks in the door from school and takes her shoes off!
Barefoot person here! I take off socks and shoes as soon as I walk in the door. I don't like having anything touching my toes any more than absolutely necessary.
Barefoot, except when it's cold, then I wear my pink fuzzy slippers (like now!) Even when it's cold though, I'll just wear the slippers long enough to get my feet warm, then I take them back off.
If I'm going to be going out again I usually still have my shoes on. If it's the evening and I'm not going to be going out or doing much walking around I am barefoot.
Preferably nothing... I am a klutz and socks are too "slippery" for me so I try not to wear those... shoes aren't comfy for me so I don't like those either. If my feet get cold, I just throw a blanket on them
slippers - when I can find them! My cats always hide them when I am at work!! They could be upstairs or downstairs, behind a door, under the bed, or in a closet. All I know is, they are never together!! It's almost a game, me coming home and having to find my slippers!
Shoes if I'm going back out (or if our Schnauzer Max and I are going out to play) otherwise I wear slippers. I have tender feet! I even have swimming pool shoes.
