Where can I buy adidas T-mac shorts?

I believe Tracy McGrady (basketball player), nicknamed T-mac, has his own brand name under adidas. And he has signature shoes and shorts. Does anyone know where I can buy those adidas shorts either in retailer stores or online. I'm just looking for shorts like these: a href="http://www.amazon.com/adidas-Mens-T-MAC-Phade-Short/dp/B000IANICE" rel="nofollow"http://www.amazon.com/adidas-Mens-T-MAC-…/a
