I agree with Will's review. The 3rd day on these things, the first small jump that I landed switch - the boots broke and were permanently on walk mode. That's absolutely ridiculous for a $720 boot made for the "hardest chargers" to break the first time I land switch. I am also a large skier (225 lbs), but gimme a break, the way these boots were described, it sounded like they were the burliest boots money could buy, yet I was able to trash them in 3 days. On the positive side, the boots were comfortable and had the stiffest flex I could find that wasn't a race fit (98mm last or smaller). If these boots were actually able to hold up when people are "charging hard" on them (as they described) then they would be perfect. BD has a lot of things to work on and now depending on the warranty, I could have just flushed a lot of money down the toilet for a whole lot of hype.
