Dalbello Krypton Cross


Pros: Smooth, even flex, custom fit, light weight

Cons: Different feel takes some getting used to

I have had these boots for 2 seasons now, and I love them.  After 20+ years in 4-buckle designs from Lange and Tecnica, these were at once a revelation and a mystery.  My first day on them, I felt like I was not "properly" attached to my skis -- the smoother, more linear flex in this boot feels much softer than what I had gotten used to in my Tecnica Alus.  I have gotten used to this feeling and can now go as hard as I want without feeling like the boot is going to bail on me.  I am 43, 185-ish, and ski entirely bumps and off-piste, if at all possible, and quite aggressive.  I do not think they would be a good racing boot, particularly beyond an informal approach / rec league, as the fairly rapid initial "breakdown" of their flex would not hold a line, IMO.  Great for all-mountain skiing.  I do not have a strict off-season regimen for fitness, and I still feel very nimble in these.  They are noticeable lighter than my other boots, and I think it helps in rapid unweighting (?) demanded in uneven bumps, crud, varying snow density, etc.  I still have a problem with foot pain on top of the instep, which I alleviate through the unbuckle-in-the-liftline ritual, but it goes away towards the end of the day, and I often find myself walking to the car still locked in tight from my last run without realizing it.  Boots (and feet!) that feel *better* as the day goes on?  What a concept...  I wear a size 9 street shoe mostly, though 8 1/2 and 9 1/2 come into play depending on brand.  I am fit for a 26.5 shell, with no further modifications to date, and it is quite snug, though as I said it packs out as the day goes on.  I only get about 10-12 days per season so I'm not the right one to talk about durability.  They should last me 10 years.  I paid half price for these, with additional $50 for local fitting as it was an internet purchase.  That was still a stretch for my budget, so at full price I wouldn't even touch them, but that's me, and my $$...  Overall a great boot, though I don't know that they are so much better than the good 4-buckle designs out there for $100-200 less.  It's what's best for you, and I think this was a good move for me.


Pros: Allows foot adjustments, but stiff lateral support, promotes lateral movements, shock absorption in bumps, CM positioning, easy on and off

Cons: Finicky fit; very small toebox and low instep. Does not promote driving tips with forward pressure


New K Crosses. These are currently set at 100 flex, which is a bit soft, but am adding Intuitions next week, which should bring to within my Falcon 10 specs. They have the stiff sole board. Fit at 26.5 is still a work in progress; these run very narrow in the toebox, and all my other boots have been 27.5's. These are tighter in the toes than my plugs before any work on them. Have done some grinding, which has helped to a point. Will have my Intuitions molded next week, which should take care of more issues. Not a deal breaker, but a pain. Literally. There are pros and cons with these on groomed, hardpack to light pow, lots of bumps:


Payoff 1: Lightening quick edge to edge, and feel oddly light/thin while doing it. My Falcons feel a lot thicker and more beefy in the barrel, more inertia. But these are pretty stiff laterally; no lateral flex detected even at high edge angles. I attribute that to the single rear piece.


Payoff 2: Bumps are suddenly a lot easier. Your boot doesn't transmit the forces nearly as abruptly back to your legs. I actually looked down a couple of times to make sure, and watched the boot flexing back and forth, but only about half as much impact being transmitted to my legs. So everything is smoother. I attribute this both to the forward flex and the very low, anatomically advantageous pivot for the rear barrel. 


Payoff 3: Keeping my CM well forward, and thus becoming more aggressive with my angles, was also suddenly easier. I found myself concentrating more on lateral movement, crossing under, less on pressuring the tips and big crossing over moves. Again, some of this seems to be that I can use my ankles now (retraction and small foot movements are super easy) without losing lateral stiffness. By comparison my Falcons feel like solid blocks welding my lower leg to the ski; using my ankles or toes requires attention and effort.


Payoff 4: Small thing, but nice touch. With a three piece design, running your power strap under the tongue, as god meant us to, is stupid simple. With most overlaps, it requires moving rivets, punching holes, or maiming the strap. OK, now to the bad stuff.


Con 1: Linear flex forward means that you use your leg and trunk muscles a lot more; no resting against the tongues and air pressure while you cruise. So more work. Time to up the workout intensities.


Con 2: You really want to get your legs out to the sides in these. If I weren't committed to becoming better at high angles and lateral, rather than downhill, motions, they'd be wasted. As it is, they require more attention to balance IMO. Cruising is less relaxing. 


Con 3: At higher speeds on ice/hardpack, not as much feedback from skis pushing against tongue. Not sure these will work as well as my overlaps for serious carving/racing, but that's not why I got them.


Con 4: So far no cabrio designs appear to fit feet that are wider in front and narrower in back, which Salomon, Technica, and these days Lange cover nicely in overlaps. So be prepared for time with your bootfitter.  


Pros: snug fit

Cons: Wore my shines almost to the bone!

I hate to write this but I feel I need to at least warn people who are aggressive skiers.   About me,  I originally from Colorado, skied summit county for 15 years, both resort and backcountry.  Now I live in Southern California.   I am 41 and ski very aggressive, I would say I am a level 8  (because I don't ski the half pipe or spend much time in the terrain park).  But I can and will ski just about anything and can keep up with most people.  I like to mix it up, bumps, trees, drops, steeps, big turns, short turns etc....

Okay,  I bought these boots because they felt great in the store, (i know, i know, demo first).  but I wore them at the store for over an hour twice and they felt great.   They are supposed to be soft, BUT I WILL tell you that the tighter you buckle them the stiffer they become.  Sooo,,  when you go to hit those bumps and crank your boots down, they get real stiff, (which is when I want them to be a little soft).  So I didn't like that but felt that with a couple of weeks on them they may soften up.   I do like my boots super tight and really crank them down, if you don't then you will probably not encounter the following problem.  

PROBLEM, On the trufit liner there is a 2 inch lump on each shin, its about 3 inches from the top of the boot, and I guess it is designed to eventually pack out and I really didn't notice it until I was skiing.  By the end of the first day I had a blister on my right shin from this lump and the left shin was a little sore, but I figured it's just because they are new boots.   By the second day I had Blisters on both, By the third day both were completely raw, only in the those spots.  By this time I should of just rented boots, but being that I just purchased them and i was a stubborn idiot and skied on them the 4th day.  After 4 days I seriously had deep holes on both shins, and I mean deep.   The rest of the boot fit perfect except for this MAJOR problem.    It's hard to realize that you made a bad purchase, and I couldn't help but think that most people who don't crank their boots down probably will never run into this problem.  But if you do then don't get these boots with the trufit liner!   I returned home and brought them back to REI, to see if they had any suggestions or could possibly contact Dalbello and get another liner.   I bought them in January and didn't ski until Memorial day and I beat them up pretty bad so returning them wasn't on my agenda.  The store clerk asked me what the problem was and I showed him my leg, (which looked super nasty and almost infected at that point).  Without another word he gave me a full refund!  I didn't even ask for one!   I couldn't believe it, KUDOS to REI to stepping up and taking care of me when they didn't have to.  I have always been a customer or REI and always will.    As far as Dalbello, I suggest they not use Truefit liners,   And find it impossible to believe that no one else has encountered this as it was really bad. 

Hope this helps, or at least brings others out.   



Pros: 3 piece boot great fit, easy to get out of

Cons: Its a bit high on the shin

Love the 3 piece boot.  These things can get really snug, and the heat molded liner makes it comfy.  Definitely a better fit than any other boot Ive tried, and the only problem I've had is that they are higher than other boots.  They come a bit higher up on the shin, so it takes some adjustment.
