I am eying these Docs in grey:

for summer. But I'm a little concerned about the chill factor and would like to be able to wear them through fall with tights or socks. Is that completely off-base? Since summer is not my dominant season, I want to be sure these will be useful and dressy enough for work (my own office, but still!).

Wisdom welcome!
