Studio is the lowest of the Ferragamo lines. They're thoroughly unimpressive shoes and aren't really a good value. Lavorazione Originale is the regular Ferragamo line. Most of the shoes are either Blake- or Bologna-constructed (mostly Blake). I've bought shoes from this line before, and I've found them to be fairly comfortable and well-constructed. There are usually some interesting models each season. I can't really say that you can't get nicer shoes for the price (around $400 per pair retail), but I don't think that these shoes are rip-offs. Tramezza is the highest Ferragamo line. These shoes have more handwork than the Lavorazione Originale shoes, and there are usually some wonderful models. I particularly like the light tan suede wingtip Bals from last season and the chocolate suede semibrogue Bals from this season. These are very nice shoes.
