Answer:
It seems that the "shoes" may evoke images of sex and adult femininity. There is conflict when she feels between her "sexual attractiveness" and the fact that she wants independence.
Explanation:
The story explains how dress up has become a different type of activity than when she was a child. Now when she puts on the high heels, she notices she has long beautiful legs. The male in the story is amused by her and then she realizes that she is being watched. She gets rid of the shoes and in a sense she is now free from the sexual idealism that she felt before.
