Hi,
I love the look of these shoes. As a life long ostrich lover and collector myself, I think they are faux ostrich. Of course, I could tell better if I had them in hand. Ostrich leather is one of the strongest leathers on the planet (if not THE strongest), and is highly prized for that quality. Ostrich leather shoes would be expensive. To sand the leather down to a sueded surface would remove many of the qualities that make it so desirable in the first place. But fashion does what fashion does, I guess. Also, the bumps we often call them, are from where the plumes were removed. Unless these were also sanded down, they should be more raised and irregular. Yours look very uniform and smooth. They are great looking shoes whatever they are.
