Pierre Hardy's first Gap collection debuted a few years ago.
The brown sandal on the right was everywhere that summer---at least in New York. They cost about $90, which isn't inexpensive for sandals, but is for Pierre Hardy. Anyone aged 13 to 60 could wear them, which means they also sold out within a week or two, and though Gap continues to put them in their print ads, they aren't for sale anymore.
Meanwhile, we've noticed Steve Madden laying off the copying. Most of his shoes are still inspired by other designs, but he's been deviating from the originals enough to keep us off his back (perhaps due to a lawsuit or two). Until now, of course.
Madden's selling an identical copy of Hardy's Gap sandal, and charging more, too.
