So far, super great!

First off, let me say that BackCountry.com has been great! I spent quite a bit of time on the phone both with sales and with the shop guys before ordering several items including these boots. So appreciated the insight given! I even needed to exchange these boots for half a size smaller and it was a pain-free experience!

After getting the liners dialed in (heat molded to some pressure points / red zones in my feet), I headed out for a break-in day at the resort.

These boots are powering a set of Rossi Super 7's (which are 116mm underfoot) via a set of Dynafit TLT Radical FT Bindings. I found them to be super light when we hoofed it a bit in the side country, and plenty stiff when charging downhill! I had no difficulties what-so-ever controlling my skis.

I'm still getting used to my setup, but so far, these boots have lived up to my expectations.

can anyone firsthand compare downhill performance of these to the ONE PX? also the differences in the stock liners of each - as they do seem quite different.

great comparison near the bottom of the comments at WildSnow here:

Great boots

First off, I don't have much to say about the stock liner as I immediately replaced it with an Intuition liner. I find these boots fit my foot way better than all of the newer Dynafit boots being made (e.g. Vulcon, TLT, One, Mercury). These boots are extremely light for how stiff they are and how well they ski. I find that the walk mode is plenty good enough for super long days in the backcountry.

Pretty pleased

  • Gender: Male
  • Familiarity: I've put it through the wringer

I picked up these boots mid-season last year and have quite a few days on them. As advertised, they are good and stiff for a touring boot. nice lateral power transfer, doesn't feel like they are over-powered by bigger skis (I'm on Armada JJ's, 115mm underfoot).
They are VERY light. I'm more than impressed. They only boast 30 degress of rotation, but I found that these boots have plenty of rotation, and I have a longer-stride skinning style which usually requires more rotation (as I've read multiple times, don't get too worried about degress of rotation).

My only quips with the boot is that it doesn't necessarily fit my foot the best. I have a wider foot, and from what I've gathered, other people have found that these boots fit narrower than, say, Scarpa Maestrales.
Also, and this isn't always prevalent, the cuffs will catch a bit when I'm skinning. This doesn't really affect performance, but it's slightly annoying.

As other reviews will mention, the plastic on this boot (Pebax) is soft, so be careful that you have the front cuffs in correct alignment when tightening the buckles, being as the plastic will deform fairly easy if you're not careful.

Overall, I'm pretty stoked on these

Whats the FLEX of the boot? Is it comparable...

Whats the FLEX of the boot? Is it comparable to a regular alpine boot? Thanks

Best Answer Responded on

My good friend owns this boot and its definitely comparable to a 120 or so flex in an alpine boot. Dynafit did not put an actual flex number on their site http://www.dynafit.com/product/shoes/titan-ultralight . Sometimes companies choose not to put a flex number because there is no set standard at this point.

Responded on

Thanks for the answer. I wanted to buey the BDQUadrant but I was told that although they soy flex 120they r much sortear than alpine boots w the same flex

Responded on

I'd have to agree with Bill based on my own experience. These are probably in the 110-120 range, although if you're comparing them to a stiff alpine boot, you will certainly notice a difference (as you would with any AT boot).
Here's a link to a really good review/discussion of this boot, as well as a discussion of the difference between AT and Alpine boots in general (the meat of the discussion is in the comments section):

Fit compared to Lange Banshee pro?

Looking of swapping to dynafit binders and boots. Don't have access to a local store. How do dynafits compare to a Lange?

Best Answer Responded on

The Lange Banshee has a 98mm wide last. Officially the Titan is 102mm, but everyone agrees it feels much tighter. Obviously, last width isn't the only measurement that defines "fit". My guess is that these would feel pretty similar. Differences could be worked out by a good bootfitter. Plus, Backcountry has an awesome return policy.

Responded on

Thanks Sandy - went with the Titan UL's and picked up some Radical FT's too!!

Responded on

Well I have spent almost 50 days in these boots.

They have a great fit, but I have been finding more issues with them the last few weeks.

They have a very low cuff in the front. Compared to a alpine boot which is higher in the front, the titan has a low cuff on the tibia and I found I wasn't getting nearly as much cuff pressure when skiing . Not only that but I found that I felt like I was going to go OVER the top of the cuff.

The other issue I have found is that the boot leaks in the toe. Every single time I take the boot out, my liners get soaked in the toe and my feet freeze.

The fit is amazing and the boots are nice and light, but I think I am going to be moving on from this boot because of the other issues I have had.

Is this boot compatible with alpine type bindings, such as the marker duke?

Responded on

Looks like the Ultralight is alpine-compatible.

Best Answer Responded on

It is compatible with full Alpine DIN bindings (replaceable toe and heel units are in the box). It is also compatible with any AT binding, tech system (Dynafit, G3, Plum) or frame system (Duke, Baron Marker Tour, Fritschi).

is the toe-box punchable? I heard this plastic isn't conducive to traditional shop-work expansion

Responded on

I am not sure, but I would bet that these blog articles would assist you in deciding-

Responded on

Yes, it is definitely punchable. Pebax shell material is more difficult to work with for the shop (compared to PU) , but most "better" shops can handle it. Stretching is more common than grinding.

Shell is Light, but plastic is soft & liner is not designed for comfort

4 negatives here:

1- Dynafit is making a flagship boot like this without producing half sizes (they couple e.g. 27 &27.5 within a 1 cm shell range. So, jumping a size if you're a half measurment like me, it could suck and prevent you from using this boot. One recommendation is buying a size up and fitting a high volume Intuition liner for it)
2- The liner is brutal near the heal. So price-in the fact you'll be potentially buying an intuition liner
3-this new lightweight plastic is really soft and subject to marring, heavy gouges and scrapes whenever you come into contact with rocks. Dynafit should look at what Salomon is doing with their Pebax undersides.
4-the green rubber on the quickstep has a propensity to "tear" and chunks can come off. Mostly, it scuffs. A more durable rubber will help in future models, because the tech hardware of the AT binder is built into these pads, and replacing this every season can get expensive.

1-They're light, really light and fly up a boot pack and you'll last longer out there before your hip flexor or lungs are shot from 4,000+ hiking. Make sure you have a good liner and foot bed or foot pain and inflaming bone spurs will cut your day short. (I bet that 80% of the buyers for this boot are veterans and have wider feet from years of skiing in hard plastic boots. They need to widen the boot near the toe section
2-They're fairly stiff for their weight. I'm impressed with the flex, could be a touch stiffer. Make more of the cuff and overlap from carbon!
3-They handle chop, inbounds, side country, and obviously powder really nicely. But so does most boots. $875 for a boot shouldn't have more than 1 minor negative.

I'm trying a size larger. If they are still too narrow, I do not recommend.

Titan Ultralight Vs Titan

I was able to demo the Titan till my Ultralights showed up, Some things to think about compared to the normal Titan- plastic used on the ultralight is way easier to get in and out of in the cold, the liner on the ultralight fits a bit bigger mostly it just feels softer so it seems to have more room this is nice and all but to help lighten the weight they do not have an option to put laces in the liner so being a little looser fitting and no laces my heel slips a little more on the up hill when the top buckles are loose, Not that big of a deal just something to think about.
All that aside I really like this boot its fast on the up hill super stiff on the down hill.

Trouble with big feet...: need a pair of stiff-ish rondo boots. Have a pair of dynafit 4s tourlites and they are just that...light! Too soft. Great for touring, but horrible to ski. The crux is my US 14+ shoe size. I can fit a 13 on occasion. Scarpa Maestrale makes a 31.5. Any one know of another big footed rondo boot out there??

Responded on

The biggest Dynafit gets is 30.0. The largest volume/width series is the Zzero/Green Machine. BD has a reputation for wider fits. They stop at 30.5.

Is there a women's model of this boot? Would the Titan work for a middle aged woman that wants light with stiffness?

Responded on

The women's model in this series is the Gaia (http://www.backcountry.com/dynafit-gaia-tf-x-ski-boot-womens). It's lasted to fit a woman's foot and calf shape. If you want to go lighter with similar power, there is the Zzero4-U (http://www.backcountry.com/dynafit-zzero4-u-tf-ski-boot-womens). You do lose the ability to switch soles between AT and alpine bindings.
