These boots are great.  I'm a weekend warrior - a desk jockey during the week, but a guy that puts his boots through heavy construction, landscaping, and farm use on the weekend.  I typically beat the heck out of any work shoes or boots that I wear.  The boots are very comfortable, solid, and stable.  Others I've tried have not been nearly as supportive as these are. The shank is also stiff, so digging and other foot work with landscaping tools is not a problem, and the arches of my feet don't feel any of the soreness that they would with boots of lesser construction.

These boots run full, but true to size.  I made a mistake in intentionally ordering a half size up to accommodate heavy work socks.  (Normally I wear a 10 D medium width and I ordered a 10-1/2 D.)  I found that the half size up was too big though, and reordered my regular size 10's which work just fine, even with the heavy socks.

One word of caution  - these things are HEAVY.  If you're wary of putting anything on your feet that weighs a lot, you may want to look at another model.  That being said, I'm very happy with this purchase.
