I voted for Converse, sandals, and boots.
Right this instant, I'm wearing slaps, which I guess are a form of sandals. Being in Florida, I can wear slaps at least 6 months a year, if not 8. If it's colder or there might be conditions where my feet would get dirty in slaps, most often I wear Converse. I have 2 pair in black, and had pairs in blue, green, and red, but one of those last 3 pairs is missing (might have thrown them out from wear).
For some gigs I wear boots, either for added foot protection, a little extra height (in one band in particular, the lead singer is about a foot taller than I), for the fashion statement aspect, or some combination of all three. I have several pair, some nice Doc Martens, some engineer boots that need to be re-soled, and some East German army surplus officer's boots.
