Take these shoes, from Chloe. They're gorgeous, kind of a cross between the ballet flat and the gladiator sandal--chic without sacrificing comfort or some measure of practicality. Had I skinny, beautiful ankles, I would covet these in a second.
Thaks to Hipster Musings for the photo.
These are not the kind of shoes that I would think would inspire copying. They're very distinctive (unlike the peep-toe Louboutins that were copied so quickly you couldn't tell as much) and they don't seem like they would appeal to the general public like flashy heels would. But here is a coply, nearly identical except for the positioning of the straps, from Anthropologie.
They're the "Jigs and Reels" ballerinas, only $88. Excellent, no?
