I've worn these every day for 4 months.  On the plus side, the boots look good, are very light, and don't take much time to break in. These are my first pair with a side zipper and I'll want that from now on.  The zippers are a bit sticky at first and need some time before they operate smoothly, but that's to be expected with this type of nylon zipper.

The first problem was with the two-snap flap that locks the zipper in the full-up position.  One of those came off the second week.  They're attached with rivets and seemed strong enough to use as bootstraps, but they're not.  The flaps are largely cosmetic; the zipper stays up without them and assuming you're not wearing shorts, nobody can see that it's gone.  A bigger issue is the insulation/padding.  It doesn't seem to be secured in place well enough and it moves around when you wear the boots.  So every time you put them on the fit is slightly different.  It creates "hot spots" that rub against your foot and ankle and when the inner lining wears through it shreds and balls up, causing even more friction.  The longer I've had them, the more uncomfortable they've gotten.

My brother's a cop.  He suggested I try Bates instead, so that will be the next purchase.  I'll wear these for the rest of the winter, as that's only a few more weeks here in Chicago.
