Why do Women love Shoes?

Most women own a pair of Black High heels When I asked few of my female friends, why girls buy so many shoes? The answers I received left me scratching my temple. Few of the replies that I got were: “ Everyone has different reasons.” “The dress should match the shoes, and the other way around.” “Because we loooooooovvvvvve Shooooooeeeesssssss.” “Accessories can make a colored top look amazing, and gives variation to eyesight.” “I buy them when I feel sad.” And the best answer that I got was: “I am shifting to my new place, and two cartons are full of shoes.” When I asked again about my question, I got pictures of those cartons. So the conclusion I came upon was that it makes them happy. But, I was still left with the question as to how those things that we wear on our feet can make a human being happy?
