They are a little bit of a pain in the ass to get them on with all tge lacing systems and boa etc. But once their on they feel really good!! The heel hold is great. They can really go from a pretty soft flex to a pretty firm flex. I would say they can range from between 3-8 on the stiffness scale. Its cool that you can add the tongue inserts to stiffen up the flex, but are you really supposed to carry them around on the hill to adjust to what type of terrain or riding your doing? That could get kinda annoying. We’ll see I guess? Also, if you dont buy these boots from a shop, where are you supposed to go to get them heat molded? I dont think a shop that sells these is going to want to help me with my boots I bought from somewhere else... Or will they mold on their own after just riding in them for a while? Would a hair dryer work to do it myself? If so, how long do you heat them, how hot do you get them, and how long do you stand still to get the mold set? This review sounds like I should have done some more research before buying them. But I tried them on in a shop and know how good they feel. Their pretty light for how bulky they look. I was surprised. 32 TM3’s seemed much heavier. I even strapped into a Union Atlas binding with these on and it felt like one seemless piece of equipment. Hopefully stays that way when screwed to the snowboard... Maybe I’ll do a follow up review after I take them out a few times and really see what they can do? Oh yeah, be careful pulling the power strap tight. The little plastic Vans tab on the end ripped right off in the store the first time I pulled on it. Gotta remember to pull from lower so I dont rip mine off. Lol!! Buy these boots!! Their bad ass for sure!! Just takes a little extra work to get them dialed. But Im betting its worth it in the long run... Pray 4 Snow!!
