I am not sure where Fratelli Rossetti is based and I feel it is a northern Italian style. I owned two pairs and both had good leather. I know it focuses on US market and Blake construction is main stream. Like many Italian brands, construction is not an issue, Fratelli Rossetti is capable of any.
Fratelli Rossetti is a fashion brand at least the brand thinks itself so, and models are released for each season. I cannot say I summarize all models but we can get a general understanding of its aesthetics.
I doubt only Americans love its design……
