They are light and comfortable.  I do think they run a little big in size compared to the average out there.  The ion mask technology to keep your feet dry does work.  Drop water on them and it just runs off.  The one and only complaint about these that I have is that they are not breathable.  They are made of a microfiber material instead of leather.  Leather breaths.  These do not.  After wearing these all day my socks feel wet to the touch when I take them off.  I do not have this problem when wearing leather boots.

I even did a test and made sure to wear the same type socks wearing my old leather boots and these new Magnums.  At the end of the day in the leather my socks feel dry to the touch.  At the end of the day after wearing the Magnums my socks feel wet to the touch.  I wear a wool blend socks that are supposed to wick the moisture away from your feet in order to stay dry all day.  So, for anyone considering these keep in mind that stepping in a puddle your feet will remain dry, but after long hours they will be wet depending on the socks.  My feet never felt like they were wet or sweating, but clearly the socks feel wet.  I have to wonder how long the boots will hold up given this problem.  Seems like they would rot from the inside out.

If these were made of leather they would be perfect !!!

EDIT:
It has now been 3 1/2 months and the lining behind my heel is wearing out.  I guess they are not perfect after all even if they were leather.  I have never had a pair of boots wear out this quickly.  I am not hard on my boots and there is no reason for this to have happen.  I will not buy again based on this experience.  I sent Magnum an email.  We will see how and if they respond.
