dxc (short for dunk exchange) is an event where people, usually between the ages of 16 and 25, gather to buy, sell, and trade shoes. Shirts and hats are also sold at the dxc. The dxc is held in large cities like New York City, SF, and Miami.
I'm looking foward to the dxc next month. I really want to sell my current shoes and stock up on some new ones.
