I don't know how many pairs of this boot I have been through and worn out over the last several years.  I like these so much I just re-order the same pair after the current ones wear out.  These are really comfortable.  After some wear and tear, they are not really water proof but they do ok.  I have had a couple pair bought over the years have defects and tear along stitch lines or the soul want to come apart.  This has not been regular enough or significant enough for me to look for something else yet, though.
