Here are some of the major shoes stores in the US. Snapshot from the Shoe Carnival ICR XChange 2008 conference. X axis stands for the choices of shoes; Y axis stands for income level of customers.
My own experience
In recent years I bought most of my shoes shoes from online stores such as zappos, and shoebuy . And I like their service and price. I understand Amazon’s Endless (shoes and bags) is popular too.
I joked with my wife some day we are going to open a shoe store in Shanghai or somewhere in China, something like the Journey’s.
