These flip flops are slim and feminine, super comfortable foam (not the shower shoe kind, though), and I bought a pair with a bit of sparkle.  I wore them all day on the first day of a vacation with zero rubbing or blisters.  The straps are rubber, which I prefer, so they don't slide at all.  I have another pair of reefs with a thicker, contoured sole and the fabric/ribbon type straps, and these are MUCH more comfortable for me.  I wore them with everything on my vacation, as I bought the brown sparkle so they are a neutral and not over the top with the glitter.  Love them.
