The Extra socks are there because they are usually 3-6 pairs in a pack and come in handy for more then just as socks. Also I wouldnt wanna wear ankle socks in the winter or tall socks with shorts. No one says you gotta look out of your normal dress routine with your spare clothing. If Im using them to stay in a friends house or hotel venturing out to stores, going out to eat so on and so forth youd wanna look and smell decent I will most likely modify it more to have clothing for "survival" bugging out and clothing for emergency bugging out.
