Tried 3 pair.  No consistency in construction, size or leather thickness.  I couldn't figure out why the left boot on one pair was very tight and the right boot fit perfectly.  That is until I measured the side panels.  The left front panel on the left boot was cut over 1/4" shorter than that on the right, greatly reducing the volume of the boot.  Could be a nice boot, perhaps if they were not thrown together in china.  Too bad, I have another pair of Irish Setter Chukkas (U.S. manufacture) that are outstanding.  These are poor quality construction.  I'm buying another pair of DANNERS.  U.S. made, great durability, great quality control.
