I have a pair of the Merry Janes and now a pair of the Ballerine Flats offered from Soft Star Shoes. They are a completely different animal than European shoes in that the shoe doesn't provide support or contour to your foot, just a thin protective barrier from the ground. They are barefoot shoes. I have been wearing mine more and more and have decided I have little to no use for my Birkenstocks or Danskos anymore. I'm planning to add a DIY pair of Merry Janes and a pair of Run A Moc Dash or Ramblers to my shoe family very soon.
eta, I really am enjoying this thread.
