Sadly, because women are more concerned with their sex appeal than comfort. Same reason they murder their feet and backs wearing stiletto hooker shoes. Same reason they go under the knife for big boobs and lipo on everything else. Same reason they starve themselves and have to go into treatment for anorexia. Beer bellied men crave the airbrushed Sports Illustrated Swimsuit trophy wives and gf.
Look at those shoes Ivanka is wearing. They are elegant..sexy..but it would not be comfortable to stand for 8 hours or walk a long way.
Meanwhile, men can wear flats.
reminds me of the ginger rogers quote about heels and dancing
