They (shoe manufacturer's) would love your business, but they will refer you to a "team" dealer. Usually a little different than a typical retailer. I don't know if you live near a Hibbet Sports, but I think about half of them are authorized team dealers. Usually for team sports like baseball, football etc.... But if they are open with Nike, adidas or New Balance for football, then they will also have an open account for track/cross country. ASICS will be a little harder to accomplish. If it must be ASICS, go to their website, try to find a contact and ask for their team dealers. Dick Sporting Goods is also usually a team dealer, but mostly Nike, UnderArmour, Reebok.
The way this works, team dealers get shoes for below wholesale (usually substantially, but not always). This allows Team Dealers to sell product in bulk at a discount while still holding on to enough profit margin to pay the bills and feed the family. You don't get a lot of team transactions, true, when you do get one, it can be for between 40 pair and 500 pair, but the fact is, you can go a while between transactions.
The manufacturers don't want to deal directly with the end consumer for a number of reasons, they all make sence. I just don't feel like going into them right now. But the main two is so they don't piss off the retailers who carry their product on the shelves, and they would have to get a business license in each state they sold to end consumers and pay all kind of state taxes, too much of a headache. That's why even at race expos when a major manufacturer is there (Like ASICS at New York Marathon, Nike at Peachtree, New Balance at Chicago, Brooks at Marine Corp and adidas at Boston) they aren't actually selling their stuff from their warehouses. They are selling a local retailers inventory, because that retailer will already have a business license for that state.
