Wow. These boots feel like heaven on my feet. They come with intuition liners (which normally cost about $200 separately!) which, in my experience, are the best for molding/break-in time, heat retention, and resistance to packing out. Also, I've used these boots a few times now but the heel hold has been superb! I have a tough time getting good heel hold but these guys really clamp down on your heel without causing discomfort. They also come with a heel hold kit if it's needed but I haven't had to use it yet (maybe when the liners begin to pack out a bit). Additionally, they boast a nice roomy toe box which allows enough room to wiggle your toes and keep the blood flowing. I have been riding some really stiff boots in the past at the cost of giving up a bit comfort so I went down a bit stiffness with these guys but they have not disappointed. Plenty of stiffness for an aggressive, responsive, double-diamond ride yet they have just enough flex to be forgiving on hard landings and be an all-around comfortable boot. One more thing: super light weight! Walking around in these is so easy and it doesn't feel like you're wearing ankle weights when trying to walk around the lodge/resort. Overall: a very well thought out and well rounded boot that won't disappoint!
