There are a couple of Mephisto stores in Paris which carry pretty much the full range of styles. That said, I don't remember where they are... I'm pretty certain on is in the 2nd Arr. If I can scare up the receipts with the address I will post it.

Go to www.mephisto.com and they have a link so that you can email all their different locations. I did and they emailed me back with the actual Mephisto concept store locations as well as stores that carried their line. I also asked about how much the pair I wanted was running in Barcelona ~$110 - they are $265 here. Guess I might be able to afford a pair after all.
