Shell Cordovan is almost always used for men’s shoes, no argument there.
I tried googling for women’s shoes made from it, and it was disappointing – just look at the screenshot I added to my post. When you search for it, Google only shows men’s Shell Cordovan shoes!

However, if you use a keyword research tool to search for the phrase ‘women shell cordovan’, you’ll see that people are actually searching for it. I understand that these are very low-volume, long-tail keywords. So there aren’t that many customers looking for this kind of shoe, let alone female customers.
But the price point is super high!… Just something to think about 😉
