Str8hungyo: You've got that right. I use the trolley for part of my commute to work that goes through SDSU campus. I see so many students on the trolley wearing flips and sandals to school year round. I don't care about the look of it, but their feet must freeze. It's been in the low 50s when I leave for work, and I can't see how these people can deal with their feet being cold.

Otherwise, it's very convenient to put on a pair of flips to empty the trash or take a quick trip to the store. Most of the time, I wear my running shoes to keep my feet protected and warm. Most of the year I wear socks around the house because it's too cool to go bare foot.
