At first I was worried about these boots being too roomy. They are slightly higher volume than the Raptor and the Dobermann despite being supposedly the same last width. The forefoot is a little wider but seems to be shorter (not as tall) as my Dobies. I kept the same shell size as my Dobies, but I think I could have gone down a size possibly. More than likely it would have required A LOT of work to downsize further, but I think the resulting fit would have been pretty snug. They do make a great tech boot - meaning they turn (carve) like crazy. I also have mine canted out 1 degree on each side to make them even more "edgy" so my opinion on their quickness is probably related to the canting. The boots also have a lot of forward lean in comparison to some others. Depending on how much ankle flexion you have this could be a good thing or a bad thing. I had the toe on mine raised so I was standing a bit more upright. I really like the strap setup on these. When you install a booster it will actually never touch the shell (sits above the shell on the tounge). These boots seem to suck off groomers but I don't know if it is the canting, or the stance. I plan to replace my Dobies next season with an Aggressor or a Raptor, but will be keeping these for slalom and other tech-type skiing. The way I have them set up has really improved my skiing.
