For the girls who hung on every word of the September Issue (2009),  who couldn’t get enough of Isaac Mizrahi’s Issac-isms in Unzipped (1995) and for model Sara Ziff’s Picture Me (2009) offered a much-welcomed peep into the big baller but less-than-kind world of modeling, comes God Save My Shoes, a soon-to-be released documentary about that game-changing wardrobe staple that girls will do just about anything for.

As I wrote in Fashion 101, shoes forever hold a special place in  girls’ hearts. The average American owns 30 pair. When SATC fashion icon Carrie Bradshaw was mugged, the assailant demanded not only her handbag and jewelry, but her strappy sandals to boot.

The obsession traces back to the mid 16th century, when Henry II’s wife, Catherine de’ Medici, discovered high heels (traditionally only worn by men). She loved how the new shoes made her look taller, thinner, more fabulous. Ever since,  women have found that heels give an instant posture makeover. Our chests stand taller, our legs appear longer and our butts get a nice little lift–pretty rockin’ results for just a simple change in footwear.

Of course, God Save My Shoes documentarian Julie Benasra features footage from modern day royalty (celebs, of course) on why shoes make them feel so fab. Look for cameos by Fergie, Kelly Roland, Dita Von Teese and more. The film is scheduled to be released later this year.
