This is the second pair of EMU Stingers I've had, so that should tell you that I'm a fan of these boots.  This is a good looking boot that really gets the job done - I practically live in these during the fall/winter/early spring months, and I have yet to have a cold foot day.  I ordered these in the "hazelnut" color, and I love the dark, earthy nut color, and the lining is dyed to match the outside of the boot, which keeps the boot lining from looking obvious when I've got these on over my pants - It's a nice effect.

Keep in mind when ordering that these do run relatively true to size.  I wear a 6.5 shoe and I've now had these in both the 6 and 7.  The 7 felt perfect when they first arrived, but as the sheepskin lining began to soften and conform to my foot I found the boot a little large and had to wear a pair of socks.  The 6 felt very tight the first day or two, but as the lining began to wear down, it is now a form-fitting boot that feels like it is custom made for my feet and toes.  So if you're in between sizes, order according to whether or not you like your shoes a little loose (up a half size) or more form fitting (down a half size) - if you're a true whole size, then you've got it made.

The "water resistant" part of the boot is comprable to the water-resistant spray treatments they sell for suede shoes at the store - they actually recommend retreating the boot once every season, so it isn't like you could wear these in the pouring rain and still have a dry foot.  It's nice that they are ready to go out of the box, and it didn't cost more for these than the regular, non-treated boots.

As for the EMU vs. Ugg comparison I see a lot of people talking about in the reviews, I have to say that I like the feeling of the foot bed in the EMU boots a lot more.  Uggs feel very flat and hard, whereas the EMUs feel softer to me.  Neither really offer very much arch support, but the EMU boots do feel better overall.
