Sure - why not? If you like them and they're comfortable, I say go for it. I have two pair of Nine West shoes - one in caramel and one in black - because they feel good, look good, and work with my wardrobe.
And years ago when I was in retail and had to wear pumps (basic pumps), I used to have about five in the same style, diff. colors because they fit my foot well and were comfortable (and you know that's important - fit and comfort- when you're running around for 10+ hours a day).
