I haven't noticed many people wearing white footwear around here, but I haven't been to the mall lately, which is where all the stylish people are. So there might be more people wearing it than I think.
I bought a pair of cream-colored espadrilles this spring and am loving them. However, I do find the look a little unbalanced in my outfits because I have dark hair. You might have more success with it since your hair is lighter than mine.
I've been looking for a pair of white booties for a year or so but have been unable to find one that I like and that fits properly. Given my experience with the cream-colored espadrilles being a bit difficult for my look, I might forgo white booties unless the price is extremely reasonable.
For me, everything is in how the item goes with my outfits. I would keep looking and trying white footwear out. I think you'll know when you hit on "the one." Or you will learn as you try them out that it's not for you.
