The boots are lovely, very comfortable, well made, nice suede, both weigh the same (400g), (a problem with other FitFlop footwear I own is a discrepancy in weight); just received so can't review their performance, but ... they are short, below calf. I had expected knee high, based on picture and 'knee' in description. In Details section, it does say 'Shorty', but I didn't pay attention to that. So be warned. If you want knee boots, keep searching.
