Seems to have excellent build quality. Moderately( 7/10) rigid sole. Good arch support.<br /><br />Negatives.Boot's Tongue could be better padded rubs at top of ankle, thick socks negate this problem. Very heavy sole.(In my opinion, the rest of the boot  will wear out before the sole ever needs replacing, to me that means the boot will be forcing the hiker to carry a little bit of un-needed weight on his feet) For those that do an extreme amount of hiking, the extra thick and heavy sole maybe perfect. Overall i am happy with my purchase. This is my third pair of Vasques. I have loved them and have given up buying a couple of other well top boot companies in favor of the high quality of Vasque.( I have purchased and worn out over 13 pairs of boots in the past 25 years, so i consider myself an expert on boots) JOG
