I have worn Burton Sabbaths for the past four years and have really liked them. I am 6'0 and 190lbs, and like to ride park and all mountain so I was skeptical about getting these boots fearing they would not be supportive enough. So far they are great! No issues with support, so comfortable, and they have all the same internal features as the sabbaths. So far I can't really notice the flex difference. A few things to be aware of though. The insole of this boot is flat, where as most snowboard boots have a more forward lean to them. Not bad or uncomfortable, just different. Maybe thats why they don't feel like they have more flex? Also the leather/pleather/ suede, on the outside is pretty cheap. After a couple of wears it loses its color(black model) and kind of gets matted down. It's just cosmetic and does not take any functionality away from the boot itself. Overall these boots kick ass so far! Great boot for only $200.
