FWIW, I can vouch for just how comfortable the shoes are. I’ve been wearing ballet flats for over twenty years, which is to say, for the past three of their trend cycles, and my pair from Mansur are the only ones that didn’t have a nasty break in period. (Everlane's comes close, and they're also marked down for Labor Day.) Buttery soft, they fit like a (foot) glove. So do like Gigi and Kate and, um, me and consider 'em before these Labor Day sales come to an end.
