I love Grane boot cut jeans. My partner calls them my sexy jeans. Off the top of my head, I don't believe they have a leather label, just embroidery where a label might be. I find them in the junior's department at department stores like Macy's, Carson's, or Kohl's. They come in long sizes, which makes me and my 34" inseam happy. Keep in mind, though, they're sized for juniors, which means they might not work for someone who's overly hourglass-shaped (they gape at my waist a bit, though not enough to slide off).
Also priced pretty well. Not sure of the regular price, but I buy them on sale for $25ish.
