I don't know what kind of stores you are used to but there is usually only one shoe on display. All the pairs are kept in the back of the store, you cannot try anything without help from the salesperson.
Including places like Modells, Macy's, Payless, Sports Authority, etc etc etc
Maybe not as consumer-friendly as what I'm used to, but it sounds heavenly from the employee standpoint.
I think the main reason for either is whether the store is built one way or another.
