I don't recall seeing these in the US, but they appear to have been one of the more successful French cycle shoe companies and they stayed in business for quiite a while. The were distribued by Ron Kitching in the UK, and I see they are listed in his catalogues from 1963 & 1970 (along with Hector Martin shoes of Belgium).
Like most companies back then they offered a few different styles such as the racing models - with lots of perforations for keeping the feet cooler, alowing persperation to evaporate out quickly. or else the Touring models with un-perforated leather. As usual, full leather construction, including the soles. Weights per pair are listed from 17 to 24 ounces (476 to 672 grams).
