Those new ones are less rigid as the old ones. There is a spring system in it, so they stay vertical when you open them: comfortable to get in and out. With the old ones when getting in and out: you had to turn them away and after getting in, turning them back. With the new ones when you are in the boot, just a slight touch is enough to get them in closing position, nice! Also the new tongue is a never seen simple turn away comfortable construction. I have a high arch, just comfortable to get in and out, this boot is a winner! Can't say anything about the liner because I have a custommade bootdoc semifoam liner in it, because my feet measures differently and due to a high arch. Unbeatable combo with the aftermarket ialian DGSS springsystem on it, http://www.extremecarving.com/forum/viewtopic.php?f=7&t=12272 Makes the boot way more dynamic in flex due to the bigger flex range caused by the bigger springs.
The buckles are microadjustable of course.
