But I think its important for everyone to own some footwear that makes them feel formidable. Not necessarily high heels or anything pointy or shiny, but certainly go for it if that's your thing. The only two requirements for a power shoe are that in them, you feel like you could take on the world, and also run 3 miles. They have to be comfortable. No one is formidable while limping.
Sharing the number one spot in my closet with some zip up black booties are these taupe JC monsters. Litas are a good place to start if you're in the market for something impressive; every sidewalk feels like a runway, and no one can miss you -- all 7 vertical feet of you -- when you're stomping their way.
