I work in a factory and do alot of walking.  I also need the ankle support a boot gives.  I previously had the Converse/Reebok Stealth but they only come in men's (even if order womens size, 'unisex' sized?).  They had more cushion in the sole than these and after a few hours at work, the memory foam insole in the Magnum is not even noticed.  I had to add footpads in the boots.  There was little or no break-in and being woman specific, my heel did not slip.  In the converse, the heel slipping rubbed a hole in the inside heel lining after 3 months and the boots were trash. Not sure if I would buy the magnums again but for the price, they will do for 6 months or so.  then the search for light comfortable work boot will start again!  aaargh!  I will say they are very light, I still think they will be hot in summer.
