Counter-counter-point, of course you'll see people in open footwear but in many busy, populated areas (especially near where people work) such as around market, civic center, soma you'll see needles and feces everywhere. Open toed shoes near those things is probably unadvisable
That's not a counter-point, it's movement of goalposts.
I stepped on a piece of metal in FiDi and in my limp to the ER to get it removed I thought long and hard about how much I like wearing sandals and what works have happened if that was a needle. I don't anymore in the city.
This is also Fleet Week, when you have people coming in from the suburbs and out-of-town who won't be as prepared.
I don’t understand what this proves other than the individual risk tolerance of every fourth person you saw this weekend.
