OMG! I'm so sorry that I missed this request. I haven't been getting updates for the AT Shoes subforum and hadn't thought to check it for months! Most of the shoes asked about aren't in my area of expertise and @shuze and @audreylita are much better than I.
I apologize.
It's probably too late for the purchase authentication but I have a couple of comments.
The Neumel Chukka boots look good to me based athough I've never seen that particular colorblock color combination and the missing style number on the label is odd. The number under the S/N has an unusual (@) symbol but I've never seen a "sample" so that and the missing style number might be a "sample" thing. Everything else looks right.
More important to point out is that Uggs/Deckers is now using what they call "Ugg Pure" which they claim is a more responsible way to avoid using virgin wool. it's made of some type of recycled wool products.
They also use synthetics that look and feel like fleece (Ugg Plush). I've seen it in Koolaburra by Ugg and IMO, it's not as high a quality material as shearling and (again, my opinion), current Koolaburra quality isn't as good as Uggs.
I'm not sure how the burn test would work on these materials, but it's a no longer valid test of whether an item is genuine Uggs.
