I bought them on sale to try before I bought them. First impression - the perfect size. I usually 7.5 or 8 US. I ordered 8 (5 AUS) and they fit perfectly. Another compliment is that they are lightweight. I was expecting the shoes to be heavier but I'm glad they aren't bulky. As far as I know they are water repellent and I plan to use a waterproofing spray before I travel to Scotland. I will let you know if there are any important changes I think.
