The brown version seemed really stiff.

From UTE (translated) of the grey version:
Fischer show here that mountain ski boot made of plastic does not mean less support and controllability than leather shoes. This shoe let me telemark skiing down black trail on both icy and rugged surfaces with good control and without weary ankles. The shoe has stiff, exterior, high heel with good grip for ankle splint and rubberized cut edge in ample height all round. It has a rigid synthetic material of the shoe completely into the lacing, which supports without bearing sharp bends. This has sole with best stiffness of BC-shoes, and board test is performed effortlessly. No pressure points in either foot or shaft which is otherwise clear it with the greatest effective, supportive height. The shoe has sufficient width for the toes, and plus for strap which can tighten heel and ankle make rail even stiffer.
Despite my powerful adds drawn pages completely against each other above the ankle, so that the lacing loses power, and it is a little far jumps without constriction between the grate and the top of the shaft which does not provide optimum tension around the ankle. Otherwise thick padding all the way up so that the very rigid ankle rail for terminals, although the tightened hard. It has good cushioning and grip around the ankle and heel, almost like a alpinsko and pronounced "rocker edge" under ball of the foot for good ski contact and drive.
It is a few degrees colder than the other BC-shoes in freezer test, which toes was confirmed in a break of "duel-trip" with Rossignol. It is non-membrane material, but waterproof far up and seems less muggy than the others. Same shoe are also made of 75mm-binding.
Basically they say it's one of the best non-plastic boots for dh control.
Compare to the Svartisen of that era:
Svartisen BC is designed as a higher version of their famous Stetind with powerful leather, Gore-Tex membrane, sturdy cut edge all the way around. It makes the leather wears significantly less.
The shoe could benefited from a couple snøremaljer to better tightening. No plastic buckles tight there is not much that stiffens from the instep and up, and there is less support in the shoe without buckles, than in Stetind and the old test winner Fischer BCX 6. PLoS is somewhat thinner than the Stetind. Flex and torsional stiffness of the sole is strangely weaker. The heel can be moved about twice as much sideways on skis as the two competitors mentioned above. When buckles jacking tight to stiffen it up considerably, both in ankle joint and over instep - just where the laces were a little lacking. With plastic buckles tight excited it still lacks some of sole stiffness from Fischer on skavlete lead, but Crispi sitting far too tight around the instep and ankle - and without mobility to easily gangehindres.
It is easy to tighten, but the shutter button to release spennne could have been markedly better: You'd rather not start with theoretical problem solving to get the boots after a long day of hard ups and great descents. Down from Galdhøpiggen was just kneeling in telemark and make nice, steady swings in close contact with the 30 cm powder along with the new 109-ski from Fischer. You can relax more with high plastic boots down from the summit, but with a little courage and skiing technique is the joy and enthusiasm not less once you master with good skis equipment.
Svartisen BC has - strangely enough - opted for a softer sole than its ancestor, Stetind. However, we have here a new test winner in the BC class as a whole provides better support, while lacing, water resistance and cold properties exceeds Fischer their shoes. The challenger also steadfast supporters of the classic 75 mm norm, especially when many of these are made with softer sole than its BC versions.
Perhaps their complaints are not well translated but owning this boot, I can say I would not want to stiffer sole. I also don't think the cuff support could be any better without restricting movement. The instep strap does seem short. These boots made me think I have a large instep, but compared to their plastic boots, no way... I'm pretty average.
They also say they prefer the Svartisen all around to the Fischer.
