Here's the Forma link

Though Forma uses Drytex and not the brand name Goretex, I can attest to these and the Sidi brand boots. Never an issue. Iron Butt 50CC, desert, dirt, water, hiking and never an issue or a prune foot.
I really prefer the Terra the most as they have a higher level of protection than the Adventure model.
At the end of the day, go with what works for you.
One added piece that, for me, made a big difference is that the Forma has a larger toe box than the Sidi. I am an 11- 4E and the Forma fits true to size and fits my foot wonderfully.
The Adventure was broken in on day one, the Terra took half a dozen rides to break in.
I run the Adventure low while on my Moto Guzzi, wore out the Adventure, and replaced them with the Terra. I wear them for everything except when doing single or two track. I bring out my Gaerne SG12s for that.
