I LIVE in flip flops and have every kind imaginable, I think. But there are differences in every brand or kind. If I get ones with a hard sole, I can't stand them. I keep the Dollar store flip flops (yep $1) for wearing in the house. I have 2 pair of Crocs which I wear outside. The best ones I think I have are Yellow Box. They are a little dressier. I have some by Clarks and Nike but I hate Birkenstocks...never can get them broken in.
I do hate the "flip flopping sound" when I'm walking on certain floors so I don't walk as hard and it lessens the sound.
I guess I'm just a Southern Girl at heart and flip flops are the next best thing to going barefoot!!
