the cool b&t
I remember when i was part of the corporate world. You'd have an extra 2-3 pairs of high heels at the foot of your desk. And then the awesome B&T fashion of wearing a skirt suit with a pair of sneakers to and from work. Not hot.
Well, these guys have awhile to go with the fashion factor, but they've gotten the technology down. Check out the Camileon Heels.
