If I’m going to work, sock/sock, shoe/shoe for what I would hope are obvious logistical reasons.

If I’m off, neither. I don’t actually care for footwear and if I have to venture out I have sandals and I don’t mind rawdogging the porch or lawn.

If I’m drunk it’s a free for all. Shoe/shoe, or Shoe/sock, or just sock, not necessarily where said sock is designed to go.
