Sock/Shoe Configurations ranked:
1.) Shoes on both feet - you are ready for whatever the world lays at your feet.
a. socks and shoes on both feet
b. shoes with no socks
c. shoes with sock only on dominant foot
d. shoes with sock only on nondominant foot
2.) Barefoot - This is how we were meant to roam the Earth. Also implies that you are somewhere comfortable, somewhere warm. If you're in the elements, most normal socks won't make a difference. Does introduce the John McClane paradox.
3.) 1 Shoe - you still have a fighting chance. A Get-It-Done foot (preferably the dominant one) and a party foot. Does introduce misalignment that will lead to longterm disability.
a. shoe on dominant foot, barefoot nondominant
b. shoe on nondominant foot, barefoot dominant
c. shoe on dominant foot, sock nondominant
d. shoe on nondominant foot, sock dominant
4.) Socks - this implies that you are indoors, probably during the fall/winter, or that you are a ninja. not very many practical reasons or uses to be in 2 socks. Slippery. CAN keep your feet warm, but more months out of the year it's better to be barefoot than in socks. Bonus for being able to conduct electricity, but not enough to overcome being last.
a. sock on nondominant foot, barefoot dominant
b. sock on dominant foot, barefoot nondominant
