I am a proup flip flop wearer! Last year I wore my Sperry flip flps, and did great. It was raining, they got soaked, and since they are slip resistant, I never once slipped. I wore my old navy flip flops once (we were just going out to eat) and I busted my butt walking down the hallway at SSR. If she wants to wear flip flops, I would spend the extra money on a pair with good support. I love old navy flip flops, but after walking all day, my feet hurt. Wal-Mart and Payless flip flops give me blisters! Croc flip flops seem to have good support. I also never had a problem with my reef flip flops. One tip I must give you is make dd wear the new flip flops for at least a few days before you go on vacation. Don't be like my dh who insisted on wearing brand new flip flops to the parks last year, and we ended up buying him a new pair mid day!!! Even the most expensive shoes can tear up your feet after a long day of walking.
