opinions on Boston got sole ?

Any guys/gals from the Beantown area hit up Boston got sole? The event is coming up December 12th. Any opinions welcomed but my question in particular is what you can sell/ trade. They allow you to bring 5 pairs. Every additional pair you bring is $5. Do the shoes have to be DS?... I wear all my shoes,....why else have them.? .....some only once or twice but they are still worn. I must trim the herd & my wife says no more until I get rid of some.. Thank you
