I ordered these boots mainly because I needed a pair for winter. Now I've only worn these a few times, so I can't comment on anything long term.

First lets talk about the pros:
-You can tell they are made of high quality materials.
-I love how the boot pulls the hell back. It feels like the boot cradles my heel.
-The outsoles grip real well to asphalt.
-The most comfortable boot I've ever own, feels like a cloud.

Now lets talk about the cons:
-The outsole near the toes are rounded at the bottom, not flat. It takes getting used to. Not sure if I got a defective pair.
-I ordered a 9.5, that's the size I buy all my shoes. Yet these feel massive. I could of probably ordered an 8.5 and still would of had room.
-These boots hug your heel, but they murder my heels also. Blisters. Hopefully this goes away with more use.
-Theres a ton of rubber on these. I feel 2 inches taller wearing them. The picture doesn't do these justice for how monstrous they look.

Really the only reason I didn't return these boots is because I figured in the winter I'll have plenty of room for multiple socks and still have room to stuff one of those warming packs in the end.

***EDIT*** 1/7/12 - After using these boots at work for the past couple of months, they have finally been worn in and stretched out. They're actually pretty comfortable and extremely waterproof. I have used these boots in sub-zero degree weather through snow, and with the proper amount of socks, they have kept my feet warm and dry.
