The only time I ever wear socks are the elastic knee highs I wear on airplanes. I do own socks but rarely bother with them. I do wear sheepskin slippers around the house most days and you don't need socks with them.
I wear socks year-round. I only have 1 or 2 pair of sandals and rarely wear them because my feet get cold in the air conditioning too. i just laugh to myself when they say you can wear whatever shoe without socks. Not me.
