I give up on Burton
These boots are a joke. Sure, they're nice and stiff...while the lacing system holds. I got 9 days out of their lousy lacing system before it quit holding the laces tight. Now, I am on the verge of a 7 day trip and I will have no boots.
They're not any better than my old Driver boots with normal laces. Plus, the laces are not changeable in the field. That means if you break a lace in the back country, you are hosed.
