French Soles definetily look and feel good, but they don't last in every day use. If you use them only seldom and inside, they will stay good, but if you intend to wear them to streets every day, you can get better quality for that. Compared to the price, the quality in French Soles is bad.
I bought a pair of black French Soles last summer, and intented to wear them as comfy but stylish every day shoes. Two weeks, and they were already looking awful, no matter what I tried to do to them. The leather is far too soft for every day use.
I have heard good things from Repetto though, but never tried.
