The intuition liner is cheap and moves around alot. I was pretty disapointed in them. Get Vans. They're liner is better than the intuition and they have added features like the anke support that make it fit better. I've been riding my BFB with the Quad liner for two years and they're they most comfortable bood I've ever ridden and the liner has been holding up unbeleivably well. I actually picked up another pair of the same boot to swap into when these break down. But i'm surprised at how long they've lasted I didnt think they'd make it 2 years and now it looks like they might make it 3.
I bought an intuition liner online to put in a pair of Celsius (their first year of production didnt have a heat moldable liner) and cooked it in the oven with instructions I found online. I'm pretty sure I overcooked them because they started to smell like they were burning. I got rid of them after that season so I didnt care. I bought some Vans BFB and took them to the snowboard shop that uses a K2 heat blower to mold liners and it worked pretty good. The surprising thing is you dont need that much heat. So I'd suggest using a blow dryer for a little while until they puff up a bit even if the effects are minimal and let them mold to your feet the rest of the way by riding them.
I'd take what this guy is saying about intuition with a grain of salt as he didn't have it molded properly and probably didn't have the right size to begin with. Let alone without looking at your foot he's just recommending what he uses which surprise surprise is pretty typical of people on forums. Oh I use it that means its sick bro!
I've heard a lot of great things about Intuition liners, but from asking around at boardshops would be hesitant to pick them up. The method used for properly heat-molding them is different from regular liners. The two shops I visited sold boots with Intuition liners (though not the liners just on their own) but didn't have this machine you need to do this. Seems like a waste to buy a boot for the liner and not even have it properly heat-molded. Buyer beware.
Eh I do intuition liners in snowboard boots at my shop. But I've also been a ski boot fitter for years and took everything I learned from that over to snowboarding. Intuition liners work wonders I have them in my K2's, I put them in my Vans last season, and I'm probably never going back to a traditional liner again. They're warmer, full custom fit, and offer way more support.
