Okay so here it goes - Just receieved the boots today.  I don't normally purchase footwear off the internet without trying them on first at a physical retail store, but I decided to go ahead and give it a shot.  I have been wearing all types of boots for many years such as military/work/hiking etc. and can say I have had the good and the bad.  For this particular boot from Guide Gear I must say it is true to your boot size.  The quality seems rather tough and durable from looks and feel and has good ankle support.  I tried them on and walked around in them a little and notice they are quite stiff, but I am aware some boots are made like this for certain reasons and others just need to be broken in later on.  The front of the boots seems a little narrow, but again I am sure they just need to be broken in.  I did notice a little/just a tad of the soles slightly apart a little in some areas, but not where the leather of the shoe meets the rubber sole. It is between both rubber pieces since the rubber sole consists of two pieces as in many other boots on the market; hopefully this will NOT have more dramatic affects later on. So with that, I applied some shoe goo just to be on the safe side, but to me other boots ranging anywhere from 100.00 on up better be good to go in the beginning (maybe I am just super picky?).  The size chart says to measure from your toe to heel in inches for correct size which is true, but I recommend going a  inch  1 full inch larger if you plan on wearing thicker socks.  Remember it is better to have larger in shoe size than smaller because you can always add insoles or thicker socks to make a snug fit.  You are pretty much screwed if the sizes are too small.  They are light boots to my surprise which is good for some people.  Also they say they are waterproof, but again I recommend adding waterproof substance for reassurance.
With that being said, I have yet to put them through a thorough field test, but over-all quality seems to be good.
