I dont recognize the brand, but those boots are a common design. If built with even the worst leather, they will tackle anything and last years. (Lifetime, only if its top notch).

In my mind, and I dont own any, designer shoes are literally designer. Not mass market. Inside the shoe it's gonna say not only the designer's name but the number of this item in the batch, because they are handmade. Think runway, red carpet, etc.

Department store brands, led by a designer and their assistants, are a wonderful value but not the same thing.
