Lattanzi is in a totally different class from the brands that you mention. In terms of quality of materials and quality of construction, there may be other makers that are equal, but I doubt that there are any that are superior. In addition, the Lattanzis in question are bespoke rather than ready-to-wear, and the that adds significantly to the price. That being said, Lattanzi collects a very hefty premium for the Lattanzi name, and it's very difficult to argue that $4000 to $10000 for a pair of bespoke shoes represents a good value. Remember, though, Lobb St. James, Lobb Paris, and Berluti all charge close to $4000 for a pair of ordinary calfskin shoes. The $10000 figure is probably for something like a Norwegian-welted crocodile wholecut. If you don't think that there can be shoes that are worth more than $500 per pair, then don't spend more than $500 per pair. Just don't cast aspersions on those who do: their evaluation of value may differ from yours. Probably someone who can afford it and who has a thing for shoes. I would never spend $150,000 for a car. Heck, I wouldn't even pay $30,000 for a car. But if you have the money and it makes sense to you to do so, then I have no problem with it.
