I recently got into a bit of a debate on this subject in another Forum and thought I'd take an informal poll here. How many pairs of footwear do you take for a 7-day beach vacation, and of what type? It would also help to know your gender, as I am assuming (from previous debate) that your answer may vary dramatically.
I'll start: I wear a pair of "formal" sandals and pack a pair of flip-flops and my dive booties, which double as "water shoes." My wife does the same, but may bring a second pair of flip-flops. So 3 pairs for me, 3 or 4 for my wife.
