I don't have any pairs of
Kate Spade or Nine West shoes, but my mom use to love Nine West until the quality went down and now finds them extremely uncomfortable.
I checked out the links to see what the shoes were made out of.
The
Kate Spade pair is described as:
Satin, suede, patent, or printed leather upper.
Leather lining.
Leather insole.
Leather sole.
And the Nine West pair is described as:
Leather, patent or fabric upper.
Man-made lining
Lightly cushioned man-made footbed
Man-made sole
Both pairs are described as having a "patent" upper and I don't know if that means vinyl or real leather, but I doubt the Nine West pair is. But otherwise, in terms of materials, I think the
Kate Spade pair will probably be better in terms of quality and comfort because I find that leather will mold to my feet and is more breathable than a man made material. But for $298, I would find out first if the upper is leather.
