I just ordered these fabulous shoes this morning from http://www.lulus.com/ and I can't wait to wear them! I've been searching for a neutral platforms for sometime now, so I could not pass these shoes up. The heel is a little chunkier than what I am used too, but after reading recent issues of Vogue and Glamour, chunky platforms are making a come back.
A recent study of high heels and the muscles they affect revealed that heels actually help build strong calf muscles (great news for runners and bikers). The angle of the foot causes your calf to work harder (think of it like doing heel rises all day long, you are working the same muscles).
