A shop in Aspen, CO has these boots on ebay see:http://www.ebay.com/itm/230912787826?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 Perhaps you could get these for dirt cheap. Has anyone tried to incorporate the UPS Lateral Flex into the AT boot? I had the first pair of Burton Megaflex boot (two buckle). They were soft (compared to other hard boots) and had the Lateral Flex knob. Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
