I'd suggest just going into the boutique and finding "the one" pair that truly speaks to you. I'd imagine that if you go in there and tell them that you're looking to buy a pair that you can't readily get stateside, they'd steer you in the right direction, since they'll know you're buying *something*.
Maybe someone here has a recommendation for a SA or two at the Paris boutiques?
Oh. And whatever you decide, have a wonderful time in Paris!
