The problem is that companies like footlocker buy directly from the manufacturers. They purchase up to 10,000 units of each item at a time then distribute them to thier stores across the chain. You probably wouldnt stand a slight chance of selling product to them. Mainly because they are getting a price that cant be beat. The manufacturers price. Then they jack up the value about 400% and sell the item to the consumer.
My advise is start your own website and sell them there. Offer a good price and sell them off of the internet.
Another bit would be to search for another marketable item. I sell several types of Items but I can specialize in seasonal items too. You know like october you sell halloween related products and january you sell lingerie and romantic crap for the valentines day holiday. ect ect ect
