The Lanvins arrived and they're fantastic! Even better than on the picure. The heel, although really 5' (they were not kidding!) feels strangely comfortable and a test run around our living room makes me very optimistic about being able to wear them around town, some time in the warmer future. For those planning to add them to their wardrobes - a word of advice: go half size up, this model runs kinda small. I'm usually drifting in the 8-8,5 area and a size 9 (the only one that was left, anyway) fits just right.
P.S. Oh, and I also found these at Nordstrom today; look very playful and they even have a name - Charlie (or Charlies since there're two of them?).
Pour la victoire - Charlie
