  1. Great Job Stano. I really liked the ski page too. Interesting how both Scarpa and Dyna offer a slightly heavier boot (+100g) for 1/2 the price. Does it really cost double to shave off those last 100g ? I will say though that when it comes to effective weight loss you’ll notice lighter boots more than any other place. I got the Evo’s last year and was amazed at how much quicker I seemed to be able to move my legs.

    PS Where can I get those Alien Revelstokes?

  2. Gimme a pair of the Alien Revy! Love it! Thx Stano for having done such a great research of to material!

  3. Shaving weight:
    Steve, I believe too that if shaving weight then boots are more important than skis or bindings, but you need to have a nice technique – not picking up your skis much.

    Alien Revelstoke orders:
    You can order them with me. Make sure you pick the right size, see above for sizing.
    Deposit is $200 with the remaining $300 to be paid on delivery…which is unknown at this time ;)

  4. Weighing the Alien 1.0 and Alien I can say that at 27 there is not a 210g difference, it is less. My scale is not super accurate but it looks to be only 160-170g of which about 100g would be the shell, the rest is the liner. So you could have a cheaper light version if you switch liners, however, the difference in stiffness of the shells is very noticeable (downhill performance).

  5. Steve, we economists would essentially classify this as an example of price discrimination (which is not necessarily a pejorative term, despite the use of the word “discrimination”):
    http://en.wikipedia.org/wiki/Price_discrimination
    Stano, my heart is kind of set on the DyNA EVO (especially since the original DyNA has been so good to me over three seasons, including the first season — before the TLT5 — when it was my only boot for all my skiing), but curious about the Alien 1.0 … what is the bsl on any sizes you’ve had or inspected, and how does the fit compare to the TLT5 and EVO?

  6. Jonathan,
    Unfortunately I cannot comment on the Aliens’ fit as I ordered both in small size for me (made a mistake). Both Alien and Alien 1.0 I have are 27MP. I weighed them, all 4 boots, on 2 different scales and the difference is not as big as Scarpa claims. Alien 1.0 was cca. 700g instead of 680g, and the Alien was lighter than Scarpa claimed, that narrowed the difference. However, as I noted to Steve I don’t have a commercial scale. But I still feel my weighing shows the difference to be less.
    As for fit, I cannot comment… or only say “yay, that hurts” :)

  7. the new 400g Gignoux Morpho 400 is popping up everywhere
    seems the top part of the bikini liner is now integrated in the cuff?
    probably so it can be trimmed down as much as possible?

  8. Stano,
    Thanks for the beta. Looks great! I see that these are all ultra-lights but I was wondering if you could recommend something for speed traversing out of all the new two and three buckle boots? So many to choose from now. I am used to an older three buckle Dynafit with the wire bails. This has been the tool for the big missions but now it seems time to upgrade. Are the newer two-buckle stiffer than my old three buckle? Or should I just go with one of the lighter three buckle for a bit more performance and they will still be lighter than my old ones. Folks are sending some big lines in some pretty small gear but I am kinda tired of compromising performance. Like; being out in the dark and having to sketch down a slope as opposed to being able to shred it. Still seeking the balance.

  9. Looks like the ISMF has ditched the 100% sole rubber regulation they were going to implement. That is good news as there were a lot of closeout prices on boots from before they made the changes!

    As for speed traversing boots, hard to go wrong with the Dynafit TLT5 or 6, if you need more beef, you can step up to the Vulcan/Mercruy/One.

    according to this discussion I found in internetland, the TLT5 is comparable in stiffness to the 4 buckle boots of yesterday, http://www.tetongravity.com/forums/showthread.php/261028-AT-Boot-Comparative-Flex-by-model-*updated*?highlight=AT+boot+comparative , though take that with a grain of salt.

  10. Hi, I have the older Alien 1.0 with the super thin intuition yellow and black liner. I am a 27 but had to go for the 28 as my left foot is very slightly longer, closer to a 27.5 and the 27 was just too neat a fit. I have been using the size 27 liners from my F1 carbons, which are a little snugger and give me a better fit in the heels. I was getting a bit too much heel lift with my right foot and this caused blisters.

    Does anyone have a comparison of the older liners with the newer 2014 intuition liner? It looks to me to be more substantial. Does it thermo form? I found thermo forming the older alien liner almost pointless as it did not seem to have enough foam to hold any real shape and certainly does not puff out to take up spare volume around the foot. I did try the 27 race liners from the old DyNa, this gave an almost perfect fit, however the cuff is too thick for the carbon collar to overlap correctly.

    Any advice greatly appreciated, I would do the obvious thing and try them out, but I cannot get them in my area and would have to buy them over the internet form the Italy.

    Great site BTW, I was in the French Alps for 5 years and have found more information on this site than I ever got there.

    Simon.

  11. Simon, I briefly tried on the Alien 1.0 with those older overlap liners before I bought the 1.0 with the sock-like liner.
    The new sock-like liner *looks* more substantial from a distance, since the padded areas stand out from the areas that have no padding whatsoever.
    But the padded areas are still very thin.
    I used them several times before having some modifications done on the shell at the heel. I had not tried molding the liners, since I was concerned about botching the process, given how they have to pulled on like a sock. I asked my boot technician about molding them, and he thought that after using them several times, whatever thermomolding of the thin material that could be accomplished had already been done via skiing.
    So overall, although I think the new liner is an improvement, I suspect it’s not enough of any improvement to go out of your way to buy them for a pair of boots you already have with the older liners.

  12. Jonathan, thanks for your reply. Your help here has saved me 120 euros. I am now in that mental mind game where I keep telling myself that I should have gone with the 27. They just felt too tight, and due to the minimal liner, you kinda know your toe is touching the shell and not the liner that will pack out. I think the next step may be to experiment with a bikini liner that is thicker in the lower part and a thinner cuff, I may even cut my dynafit liners and sew them up at the ankle hinge. If it works , I will then cut the cuffs from the alien liner and fit some Velcro to them.

    Thanks again

    Simon

  13. Simon, maybe I saved you money, but I still haven’t solved your problem!
    Looking back at this:
    ” I did try the 27 race liners from the old DyNa, this gave an almost perfect fit, however the cuff is too thick for the carbon collar to overlap correctly.”
    - My suggestion is to have a boot fitter remove some additional foam from the upper cuff. Or if you’re handy, you can do it yourself with a surgical scalpel. I’ve had this done to the toe box of my Zzero4 liners years ago, and more recently to my Dynafit EVO boots.
    - Alternatively, the homemade “bikini” liner sounds intriguing, and will even lighten up the boot a bit, but I suspect that even slight shifting around of the parts will cause endless problems.

  14. Jonathan, thanks, I never thought to strip the cuffs down. I removed the tongue and rear cuff reinforcing patches and this allows the carbon cuff to overlap enough to close correctly. In a carpet test, the boot fit now feels correct, with heel lift eliminated, an all round snugger fit and all for a weight increase of only 36g per boot. With the reinforcing removed there is still more cushioning than the stock liner which will remove some of the harshness due to the stiffness in ski mode. Also there is no noticeable difference in the ankle rotation. So I am very happy, now I can’t wait to try them out.

    Thanks again,
    Simon

  15. Simon and Jonathan,
    Haven’t fully read your comments so just a general side note – by ISMF rules you are not supposed to alter your equipment at all (apart from some fitting adjustments). So just keep that in mind when doing mods and want to compete in sanctioned races.

  16. For those of you who have tried some of these boots, can anyone give me advice on which you think would be best for cold-weather climbing? I’m planning a speed ascent of Denali and I want a boot that will ski well, but then excel when I toss the skis and hike up the rest. Thanks!

  17. Roeske, both of these boots are if anything *too* warm for my feet, but that’s moving fast in winter New England and late-spring/early-summer PNW.
    For truly cold weather mountaineering, I suspect that only solution is to size up a full shell and then stick in a thicker/warmer liner — probably something from Intuition’s extensive line-up.
    I also suspect that your only model option is to the 2013-14 Scarpa Alien (“0.0″) with the internal gaiter, as the Dynafit EVO & PDG might let in too much snow, and using the proprietary gaiter with the Alien 1.0 might be too much an annoyance in that kind of environment … unless a non-proprietary gaiter would work with either the EVO/PDG or Alien?

  18. Hey Jonathan,
    Thanks! I am planning to use an overboot like those made by 40 Below. I just got a rash of these boots in the mail today that I’m gonna try on and send most back… Hoping I pick the right one!

  19. Hi Roeske,
    Seems like Jonathan and I agree as I emailed you similar thoughts :)
    Let us know what you chose and how it worked out ;)

  20. Man, this Skintrack community rocks!
