These boots are my second pair, but it seems there has been a quality change. My first pair were super with Vibram souls these ones don't have it any more, and a different quality of Neoprene boot altogether. I can't compare this boot till it has done it's time. I get sore shins as the neoprene is different and doesn't fit as well. I bought these online and couldn't test them before receiving in the post. Initially I am disappointed but will test them first. My first pair were Super, shame that they had to change there design to save money and for more profit.
