In reply to John R:
I've had a pair of Zodiacs for 18 months now. They have been great, I had a pair of cruxes before them so can compare directly.
The uppers of the Zodiacs have not lost any shape and are still pretty solid. It's a sock like fit which is still precise because the uppers haven't stretched. Underfoot they are in a different class to the crux, more like a light boot with the upper cut down. The soles of which were pretty soft. You don't feel any pebbles through the Zodiacs sole. I got mine perhaps a half size too big(42.5) and have only ever done VF in them, for which they were fine. If I'd got 40s I think I could do moderate routes in them. (Though they are not anywhere near as good as my old Sportiva Riockjocks for that purpose).
They aren't waterproof which is disappointing for a shoe that expensive, (and they are quite heavy) nevertheless they are quality footwear. I'd recommend them.
