I've always been partial to Steve Madden's boots. Steve Madden likes to jack styles from runway designers and sell them at a cheaper price.

I have the Intyce boot in black: SteveMadden - INTYCE COGNAC LE women's boot flat casual

And omg, it's SO comfortable. After wearing flat boots, I will never go back to boots with heels. I can work an entire day on my feet in these boots. I love it so much I might get the same boots in Cognac.
