The only negative responses to Nike has been the problem in Asia. Otherwise, the kids love their swooshes. Every year they come out with new styles, and every year those are the first things that are sold out of the stores. The swoosh won't die until another company can bust onto the scene. I don't see that form any other company...unless its Adidas who sponsors Notre Dame athletics. i don't know the student responses but form athletes that I know there, they say that they do an unbelievable job at taking care of the athletes. Hope this helps.
the good: Nike is an awesome brand. Everything they do, they do big. Look for a big golf move soon. Tiger Woods is just another example of their excellence. They will take golf to yet another level. They are as competitive as a business can be. Thay hate to lose. That's why they win all the time.
the bad: my sixteen year old and all of his friends will not wear Nike's. They are all jock's. New Balance' Saucony, Puma, Aisecs, Adidas, Reebok, they'll wear anything but Nikes for all sports. Also, go to your local sporting goods store and take note of the incredible amount of Adidas wearables.
