None of it looks genuine to my eye. The upper white part just looks like some kind of embossed, embroidered man made product to me.
The lower part, I don't know, but look at the last pic, the boot on the left. Look towards the top (of the lower piece), the left side, where it curves up and then back towards center. That edge looks like it's de-laminating. The whole edge just doesn't look like a natural product to me.
Where the strap ends are coming apart at the top just doesn't look right, either. Too frayed and thin.
But then, pictures can be quite different than having something in hand. I hope I'm wrong.
