I was looking through the catalogue, and it appears that there is a honeycomb type thing happening on the side of the boots. Theres also 2 models it looks liek of the 1080 boot (unless I read it wrong). Infact, the little instruction booklet on some of the later production 04/05 botts has a picture of it.
I forgot to grad a copy of the book, so if anyone has some photos, could you please post them (or a link to them).
