The first rule of Flight Club is do not talk about Flight Club. Wait, actually, they would like for the word to spread. They sell shoes, tennis shoes especially, and their wares include shoes that are particularly rare or otherwise difficult to find, as well as the latest and greatest that the market has to offer. The way they're able to get some of their more obscure stock is by allowing customers to use their store to sell their own shoes for an 80% profit of the quote. Flight Club also offers apparel, since wearing only shoes is frowned upon in civilized society, as well as hats and accessories like snazzy sunglasses. Only snazzy sunglasses.
