the box is definitely fake...because ugg boxes dont come with blue print..and..there should be a small orange sun around the word UGG...on the middle of the box.....these gold ones just came out in 2007, and all boxes should be designed the same, i just bought 2 pairs of uggs this year from an authorized retailer and the official ugg website and their boxes don't look like that.

and i've seen fake uggs before, there's no difference between the material they use, it's easy to copy the style, material, even the bottom of the shoe can be the exact same as authentic ones. It's the stitching of the shoe that will tell whether it's fake. Also, when the rims of the shoe doesn't match the sheepskin on the outside...then they are fakes too because UGG australia always match the rims of the shoe to the color of the sheepskin on the outside.

just some tips from my own experience, hope this helps
