The soles fail.  There are gluing issues....as the first pair I owned, the yellow support patch on the instep came off.  Shoe store took them back and replaced them.  2nd paid have lasted year and a half but sole is loosing black nobbies through out their life.  Early on the outside of the foot, and now they're pealing all over.<br /><br />I also feel....my feet just instantly sweat more than other boots I've owned.  I'm not why, as it seem excessive.<br /><br />The one thing I liked about them is the time I've stepped in deep mud, the boots just shed the mood soon after.
