Lets start with the pros: fantastic park/freestyle flex. Gave me a more skatey feel, forgiving, and tweakable.
Here are the cons: horrible ankle pinching. Rode in discomfort for three days. Tried molding the liners, but it still didn't help. Now, I ride with constant ankle pinching. Buyer beware.
I've rode Burton Assaults for two seasons, which fit like a glove. Burton's Warranty department made my experience even worse by rejecting my complaints as disingenuous. Another friend of mine owns these boots and has the same ankle discomfort. He thought it was normal because he rode a pair of uncomfortable boots for 3 seasons.
