(Though they've been popular for a couple seasons now....) http://www.nytimes.com/2007/03/25/fashion/25street.html?_r=1&ref=fashion&oref=login Photographs by Bill Cunningham/The New York Times By BILL CUNNINGHAM Published: March 25, 2007 The snow hadn’t disappeared from the streets of New York and already the first trend of spring could be seen up and down Madison Avenue: the revival of flat ballet-style shoes. In the 1950s, they were a popular alternative to spindly high heels; designers of calf-length full skirts showed their fashions with ballet slippers made by Capezio. At the time, such shoes were not commercially available. But today many manufacturers produce variations of the ballet flat. Not to be outdone, a carriage horse in Central Park showed off its own spring shoes: hooves painted with purple glitter.
