Anthony Vaccarello is not only an excellent fashion designer, he is also adept at physics.  During the latest Saint Laurent show, Vaccarello debuted his newest shoe design, a traditional pointed toe pump with no heel.  Instead of a traditional heel, the design featured a flat shank which extended along the floor.  The shank is an equal length to the shoe itself, which means that the downwards pressure exerted from the wearer is equally spread between the toe of the shoe and the back part of the shank.  The shoe was black patent leather, with a lettering design on the flank.
