A shoe shop is read as choosing the path you walk and the way you walk it. Shoes that do not fit can stand for a direction that does not suit you.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
