Giau's are the 3 strap, right? They appear to have many similarities in construction and fit with the Dominators. It appears the Dominators have replaceable soles unlike the Giau. I was afraid the hard plastic soles would be very slippery on rocks but they've been OK and sure last longer than rubber soles. I wish the Sidi heal was wider, it's easy to turn an ankle - I guess its too narrow to save a couple grams.
