Most Helpful Girl
I hate such categorical statements... But I guess in general terms you're right. They are a big deal for many girls.
As far as I know I'm a girl and I there's no way I could be more indifferent towards shoes. I'm the overestimation of shoes you are talking about is just another proof that our society is ruled by materialism and consumerism and we're just a bunch of stupid lambs doing/buying whatever big companies and advertising tell us to.
