If I paid more for them, I would have returned them.  The double zippers are not necessary because the boot is more than wide enough to slide on and off without opening either of them.  The seam across the top of my foot rubs on a bone and causes me discomfort.  Too wide in the leg part by an inch or two.  Otherwise a nice boot.

Not sure how warm they are in cold weather since it's really warm here right now, but the lining is quite nice.  Just wasn't quite what I was looking for.

I like a closer fit to my leg because we get a Lot of snow in the winter.  If you're wearing a shorter style boot it needs to fit tight enough to keep the snow out of them.  Waterproof is great until the snow spills over top of the boot an onto your feet!

The Christy style of this boot is Much Nicer but may no longer be available for purchase.  Happy Shopping!  :)

UPDATE:  The insole of this boot is really messed up after just one winter.  Not as warm as I hoped, but warm enough if your winter only gets to -20 or so.
