I went to 19 Rue Jean-Jacques Rousseau during my trip this past week hoping to find something unique or to see if they had the hard to find size 42s. I asked the SA if it was worth going to the other shop for my size 42 specifically and she didn't think it was. They only had 2 pairs of 42s in the store...very plain styles. The styles that were out on display were nothing special that can't be easily found in the US. The SA concurred that I have access to everything they sell there and probably more in the US. I got lost finding it the first day I tried because the road splits and the Rue Jean-Jacques Rousseau I walked down the first day was higher numbers. At that point I was exhausted as I had been walking for hours (tried to skip metro and taxis as much as I could to explore the city streets and get exercise) and my cell phone was dead so I tried again the next day and finally found the right block. Here are pics I took of the shop.
