Description

The DynafitZzeus smiles on skiers who worship downhill performance whether earning their turns or ripping the resort.

Dynafit throws down the alpine touring cross-over gauntlet with the Zzeus TF-X Ski Boot, a burly four-buckle downhill charger compatible with any alpine or AT binding rig. Dynafit designed the Zzeus around an alpine-style overlapping shell for increased downhill support and a more progressive flex—not to mention easier entry. The Zzeus’ Triple Binding Sole system–interchangeable sole blocks for either standard ISO alpine bindings or touring setups–makes it a one-boot solution for freeriders who use a variety of gear. This boot’s walk mode offers excellent fore/aft articulation approaches and ascents.

What determines right or wrong side installing the toe piece on these?
I assume this applies only to the AT sole set up?

anyone have a recommendation for crampons that pair up well with this boot?

Responded on

The Grivel Haute Route Ski Matic Crampon comes to mind as the ideal for ski mountaineering. However, if you're looking for more versatility, look to the Grivel G12, BD Sabretooth pro, or BD Cyborg pro.

I use Petzl Vassak's Flex locks with mine and they fit nicely

Excellent after expert fitting

Used these for 2010-11 season in Colorado. Home area is WP/Mary Jane, and my resort boots are SpeedMachine 12s driving XWing Fury (164). I'm 6'4", 200 lbs. and love bumps, high speed turns, and powder, and this setup is great for everything inbounds. Got the ZZeus to mate with Rossi S3 (177) for side- and backcountry. I've got high arch, wide ball of the foot, and narrow heel, so I took a risk getting Dynafits. The boots absolutely killed me until I had a bootfitter heat and stretch the forefoot, and I replaced the liners with Intuitions. Now these boots are friggin' sweet. Heel lock is dialed in while my foot does not pound with pain; I can ski all day in MJs bumps, or skin and ski all day in the bc. Skinned around Monarch, Berthoud, and RM National Park in absolute comfort. I would like more forward lean, though. The need for fitting and lack of forward tilt are what keep me from giving it 5 stars.

Responded on

Kevin,
What is the name and location of your boot-fitter. It took several months for the pain in my feet to abate after the season. I had to pass on a few bc trips due to pain last winter/spring.

Thanks

Zzeus finally

Been skiing a long time and this is the first I've actually felt like a different skier as soon as I put these on. The immmediate difference was the "locked in" fell on my heel. No movement or shifting at all. At the same time, plenty of room in the toe box for comfort. That's a rare combination for any boot. I have a slightly wider than average foot and this boot felt snug but did not bite. I'm sure after a proper liner fitting they'll be even better.

The biggest difference was the immediate response to any lateral movement over my Alpine boots. This makes for a much quicker respones and a better carving feel to my 111mm under foot skis. Even on packed powder doing fast carve turns on early rise skis. I would recommend these boots to anyone who wants to improve their skiing. Don't be spooked by the reputation that Dynafit is only for people with narrow feet (I'm not sure what the last is rated).
One note: These boots are a little harder to get in and out as a result of your heel being "seated" in more than your typical Alpine or AT boot but the extra effort is worth it. The interchangable sole blocks are totally cool. It works great after learning how to do them on the first attempt.

So I have a question, I have the garmont...

Posted on

So I have a question, I have the garmont endorphin's size 27, which are to large after a couple of seasons. I have a narrow heel and a wider fore foot. For lighter trips I have the radiums size 26.5 (cold feet!). Tried the dynafit Zeuss in Davos but these feel narrow in the forefoot. A season is about 30 days for me, I like a stiff AT boot but I find it difficult to get the right one. Preferably Dynafit inserts. Is the Mobe 26.5 a good gamble? Strong skier / ski mountaineer, weigh 72 kg.

Best Answer Responded on

The mobe looks like a great boot...You should try the intuition liners!!

These boots are going to take a life time to break-in.
Lacks forward lean in ski mode. Not the cozy fit most readers have experienced. I'll have to ski these for the remainder of the season to form a better opinion. I have only spent 2 days in them so far and I have scars on my shins from the first day using them.

Responded on

I have horrible blisters as well from booting up a 45 degree snow slope in these things. Turned my shins to hamburger patty

Does dynafit sell three buckle boots? If...

Posted on

Does dynafit sell three buckle boots? If so, are they lighter than 4-buckle. What is the advantage of 4-buckle?

Considering a major investment after using X-country skiis for ten y ears.

Responded on

They sell some ultra light race boots with 2 buckles, but no 3 buckle boots. The 4th, or toe buckle, well some people like to crank that down, but I really dont', so the only advantage to me is maybe the dispersion of torque across more points of the boot when needed. I think some people think a 4 buckle boot is "burlier" but then again I skied the Agent AT 3-buckle boot and loved it. I did notice a little more wear at the single lower buckle cross point on the agent AT's but this could have been due to the construction of the plastic, or the metal loops they use on their buckles (Tech..not dynafit)

Responded on

The used to sell the green monster in three buckle version: http://www.backcountry.com/dynafit-zzero-3-c-tf-alpine-touring-boot

It's not as stiff or supportive, but it does shave some weight off. The 4 buckle boots provide a better fit overall and lock in the foot better for more support. If you are really interested in it for the weight savings, my advice would be to get some of the higher end carbon boots like the tlt5.

can I use these boots with my regular alpine bindings?

Responded on

Yes, it somes with alpine sole blocks that are easily swapped for the AT ones.

Responded on

Agreed, 8 screws out, 7 screws back in per boot and you are done. Make sure the toe pieces are on the correct side, and don't forget about the extra 8th screw that goes in the back to hold the dynafit compatible rear insert in place!

It take me about 10 mins to do total, in front of the tv, with no real effort. A leatherman gets it done, screws just need to be hand tight. Cince them down a little bit at a time, working around the boot to different screws in a circuit.

Only complaint is the forward lean

The boot fits very well and provides more than enough lateral stiffness. Is there any way to increase the forward lean of these boots in ski mode?

Responded on

Here's what it says in the boot manual: "flip rear heel lever into walk/unlocked mode (fully elevated) and using all your weight, flex the boot forward as much as possible. While in that extremely flexed position, push the lever down, reinforce your cant with another strong push and slowly stand up until you hear the locking click of the ski walk mechanism."

Responded on

The specs show 15,21deg forward lean, how do you adjust to more (21deg)forward lean? This explanation above seem like a strange way to adjust forward lean. I tried it and it doesn't seem to make a difference. Maybe I'm doing something wrong.

Low Profile, High Performance

Like it a lot, great boot light weight, stiff, good for touring in...but.... Had some issues with breaking the boot in. Normally I'd think it was just me but I have heard this from several other people as well. Dynafit's fit VERY slim to my understanding. This is not where the issue came from. I had some issues with the rear on one side, which I had taken care.

The ISO sole blocks are included, which is nice if you want to try some demo skis out and your local shop doesn't mount things with dynafit or AT bindings. Just be sure to give these boots some break in time before you have to head out for a big tour. Don't buy them the night before you leave to do the Haute Route.

These boots can handle high energy skiing on steep lines. They can charge hard, so don't be afraid if you are joining the ranks of the newly converted. If you are one of those people and are looking at this boot...welcome home, your feet never have to hurt again, and you can hike and ski 55 degree chutes in light, comfortable, high performance AT boots!

Haute Route Conquistadors

Very comfortable. Completed the Haute Route with these after only three ski days in them to break them in prior (and had no foot discomfort during the entire tour!). A bit heavier than some other AT boots but sturdier too & thus great for crossover use as a regular downhill boot. No regrets about purchasing these bad boys!

Responded on

Interesting choice in gear for the Haute Route. Verdicts = stiff, somewhat heavy and wide ski. Zzeuss = stiff, freeride touring boot. Duke/Barons = not the best tourer out there.

Looks like you had fun though!

¡Increible!

This boot is the sh**. Fits most feet really really well. Great heel pocket, not too high volume in the instep, and wide enough in the forefoot for most. Really bomber overlap construction means they ski like a champ, but they're still light enough to kill it on the up. Some durability issues with the liner, but other than that this is a winner.

Responded on

replacement liners are available as well, or you could go with a non stock. Rather have a shell outlast a liner than the other way around! (right?)

Review Title

These boots (albeit spendy) are just about the best. They ski in the resort well, are super light, articulate while hiking well, and with the interchangeable sole pieces, they should be the last boot I buy for years and years. And I work in them patrolling +/- 120 days a year. the only issue was a narrow liner, but i didn't get them thermofitted, the easier solution for now was to put my comfy garmont tele liners in them, which fit my wider foot. They still ski great with that modification, if not better.

Were dose Dynafit split its shell sizes....

Posted on

Were dose Dynafit split its shell sizes. On full or harl. For example does a 28 and a 28.5 have the same size shell or a 27.5 and a 28?

Responded on

Each whole number has the same shell as the half-size ABOVE it. i.e. 27/27.5 are the same shell.

Responded on

Also, 26/26.5= 302mm BSL, 27= 312, 28=322. for how coveted boots sole lengths are, the ski industry does a pretty good job at keeping them a secret.

What's the last on these boots?

Best Answer Responded on

Apparently it doesn't matter enough for Dynafit to put it out there, probably like a 98mm.

Responded on

I spoke with Dynafit about the last on the ZZeus and Titan today. The last varies with the size of the boot. Size 27.5 has a 102 mm last. Size 29.5 has a 106.5mm last, so it looks like they go up 2.25mm with each size.

Great boots, great fit

I got these boots since they fit my skinny, high arched feet way better than any of the Garmonts or BD's I tried on. Uphill they are light enough and are fairly comfortable, downhill they are super stiff. These are my first AT boots, and after a full season of resort and backcountry touring I can now say that I will never go back to standard alpine boots, or any other brand for that matter. The absolute best thing about these boots is that after a full day of touring/skiing, my feet feel fresh and pain-free.
