I bought some shoes there last weekend. It's OK. The Nike Employee store carries a lot more but the Adidas gear is comparably priced and the store far less crowded.
It will be close to the same stuff just newer versions from when you were there last. I go a few times a year and usually they dont run out of shoes but Blazer Jerseys can be sold out pretty fast.
Like Nike stuff, I can get the product name 50% off if I bargain hunt. But what's grea tabout employee stores is you get all new and latest fashions for 50% off. Won't let another pass go by unused.
