I'll echo what dd says, both about this specific boot AND the liner.

They DO drain exceptionally well.  You WILL need to double-knot the laces; they will come apart on you otherwise.  During our 12 day WCP trip, even my double-knots started coming apart.  I strongly suspect this is exactly what caused the significant problem I experienced.

With or without a liner, you always want to be certain your foot is not slip-sliding around inside of the boot.  My liners started feeling pretty greasy inside of my boots during rough bushwhack on Day 3 when we were climbing cliffs and then descending into swamps.  The end result is that I ended up with some of the worst blood blisters of my life & lost 3  toenails.  I'm not exactly sure why they started feeling so greasy & slippery inside of the boots; could be the liners simply didn't match up well with the wool socks I was wearing.  They did OK on Day 1 and Day 2.  Maybe I should have changed them out before Day 3?  It could be that those boots simply aren't meant for the kind of climbing we were doing that day.  More likely, however, it was that the laces kept coming undone, thus allowing too much wiggling of feet inside of the boots.

Don't get me wrong; I DO like the boots.  They drain nice & provide good support.  I may have to try some other laces on them, however.  Those that come with the boots simply will not stay tied!
