The following is only my first impression.  I've served in the military and have worn boots all my life so I know it's a little unfair to judge a boot too quickly, but...

There's a ton of vertical wiggle room in the toe area.  I can easily curl every one of my toes, or cross my big and long toes.  While that may sound good, it's just not normal.  I've never had a boot with this much room in the toes, top to bottom.  Even after putting in a gelled insole there is a little too much wiggle room to call it perfect, but it's not a big deal.  As-is though I'd give that portion of the boot 3 stars.  4 with an insert.

They also seem to run close to a size too big in length.  These 12's fit more like 13's, but again, with thick socks and insoles they're closer to satisfactory than not.  They're close enough to where I don't wish to return them for a smaller size, but if I were to order another pair I would definitely go down a half a size; and yes that's even after the gel insert and socks.

I only have one big complaint and that's the way the toe curls.  The crease that's created while walking, where the toes bend up... it digs into me pretty good on the top of where my toes meet my feet.  I'm hoping that once they're broken in this won't be an issue, but for right now I'd have to say they dig in worse than any boot I've had other than this one cheap pair of Walmart steel-toed.  They might even rub me raw before they get broken in.  As I walk around in them I'm really questioning if I should return them or not, but my gut tells me to wait until I break them in because this boot, as a whole, is outstanding.  For the most part they already feel more like sneakers than boots.

They are very light and from the heel on upwards they are the most comfortable boot I've ever worn.  I love the tread pattern and can tell they will have superior all-terrain grip.  The rubber soles are also relatively soft and I'm sure they will grip on wet surfaces just as well.  Being soft, light, cushioned and comfortable I have no doubt these can be worn day in and day out without complaint.  I feel they are the perfect height.  I'm also fairly confident, judging by its apparent quality, that these boots will last quite some time.  The only parts that aren't double-stitched are the lace eyelets and that's probably because there wasn't enough area to do so.
