Not all relationships require compromise.

For years, there was a common perception that a boot built to tour uphill couldn't possibly ski well going down. Well, the Vulcan MS Alpine Touring Boot from Dynafit is here to shatter that perception. There are a number of features to love about the Vulcan when in the skintrack, starting with the weight—these bad boys come in at just about 3.5 pounds per boot which is extremely lightweight for a boot this stiff. The 103mm last has plenty of room for your toes on the way up, which is especially nice to help maintain good circulation on colder days, and the 60-degree cuff rotation should be plenty for even the most ardent yoga enthusiasts.

The beauty of the Vulcan is that the fun doesn't stop when you get to the top of your run. Simply plug in the removable downhill booster tongue and your boot becomes a stiff, freeriding machine. The boot is plenty skiable without the cuff, so lighter riders, or folks that prefer a softer feel from their boots may just forgo the use of the booster tongue. The Vulcan sports three metal buckles, one of them being an innovative, new centrally located buckle directly on the shell pivot points. When engaged, it helps to keep the cuff and shell compressed, adding to increased stiffness throughout the entire boot. The Dynafit Pro Freeride sole features three different rubber compounds for use on both the uphill and the downhill. There is a soft rubber that offers excellent grip on slipper rock ridges, a hard substance designed to work with modern step-in binding systems, and a medium rubber that is a good compromise for areas that need grip but are subject to high amounts of abrasion as well.

Really great boot for touring and resort

  • Familiarity: I've used it several times

These are fantastic touring boots for my skinny feet and legs. They are my only boot now for resort and touring. The wide toe box is great for long tours. The stiffness adjustability with the extra tongue and cuff stoppers is great. The break in period was a little more rough for me that most boots, but after several days they really got comfortable. I am very happy with these boots so far after half a season of touring and resort days.

Great Boot for the Up & the Down

  • Familiarity: I've put it through the wringer

The Vulcan does its job, and sure does it well. It walks and climbs well, but also skis well. I was skeptical before getting them that they would be stiff enough for my liking, but they turned out to be fantastic. The range of motion, lightness, and walkability seem to be the perfect combo for me for touring. Then for the down, the lock into ski mode is solid and when it is locked I know I can rely on the boot, no matter what I'm skiing.

A league of its own

  • Familiarity: I've put it through the wringer

Skis well, climbs well and is very warm and durable. I've skied this boot as my daily driver for the past year or so and I have been consistently impressed with how stiff it is even without the tongue.

Best boot up and down

  • Familiarity: I've put it through the wringer

I'm over 300 days into my original pair of Vulcans, riding these in slackcountry, on hill, and on bigger 10k vertical ft + days of touring. I've basecamped with them in extreme and extended cold, with only positive feedback to report. While other boots in the same league as the Vulcan say they have equal range of motion for the way up, these are still the kings of uphill/downhill performance. Other boots require a lot of energy to actually use their full range of motion, while the Vulcan is such a smooth stride. I'm still on all original parts, and these have been so reliable over the years. They've got a high, stiff cuff and tongue that make the downhill feel super confident as well. After 300 days on the same boot, even with a ton more options out there, I just bought another pair of Vulcans.

My hip flexors have never been happier

    I've been touring with modified Lange plug boots up until last spring when I was able to get my hands on a small pair of Vulcans. I don't want to be too hyperbolic considering any boot would be a huge improvement in terms of range of motion, but these boots not only toured great, but I felt like they were solid on the way down. I didn't get the riding the wave like feeling like I have in other touring boots. I didn't use the tongues as the stiffness would be nice but I find the boot doesn't flex as smoothly.

    Raise a glass

      Big cheer for the Vulcan. This boot is hands down top shelf in skiing and touring. The biggest gun in the boot game

      Amazing product

      • Familiarity: I've put it through the wringer

      This is an awesome lightweight boot that has great stability. I have used it in the park and of course the backcountry, the range of motion for touring is large which helps tremendously and I know I can trust the boot on the way down.

      Unanswered Question

      Obviously compatible with tech bindings, but are these also compatible with standard alpine bindings - ex. Salomon STH drivers, or look pivots? Or do they specifically have to be WTR?

      A little awesome, a little not awesome

      • Familiarity: I've put it through the wringer

      These boots are awesome, but there are a few things I don't love about them. I do like the range of motion when in walk mode, and I also liked the option to take the tongue out to have a softer flex. What I don't like: the booster strap has to be taken off to have full range of motion touring, and the top buckle often gets caught in my pant's gaiters when I go from walk mode to ski mode. All in all, I think this boot is a great entry level boot for backcountry skiers that already shred hard. I also think it works well for guides and instructors because it is super comfortable!

      Good Boot But Unreliable

      • Familiarity: I've put it through the wringer

      I have skied this boot for the past few seasons. It tours well and skis well overall. However the problem arises with thier ski/walk mechanism which is just the top buckle of the boot. I have snapped at least 6 of them by now. This presents a real issue because once they break you cannot keep the boot in ski mode properly or tighten the boot. I have had this happen to me half way down a 40 degree couloir which could have turned into an epic if I was unable to jerry rig the boot to stay locked in ski mode. Sometimes this part is easy to obtain and replace other times i've waited many weeks to get the part as they were out of stock. Will likely not get another dyanfit boot with the same sort of ski/walk mechanism

      Will you be getting more of these in the near future? After size 28. Cheers.

      Favorite Boot

      • Familiarity: I've put it through the wringer

      This is the best ski boot I've ever used. Light, powerful and comfortable. Tall supportive cuff helps me feel in control and transfers my energy into the ski. Great range of motion in the cuff, makes for smooth strides while walking, skinning and bootpacking. Comfortable enough to wear for 10-12 hrs a day while patrolling or teaching avy courses. I wear them a half size large for toe wiggle room (makes a huge difference in toe warmth). Resoleable. I've gotten 3 full seasons out of them. Will get another pair.

      Best boot I've ever skied, up or down

      • Familiarity: I've put it through the wringer

      These boots ski better than my old Lange's on the downhill, Pow or Hardpack. Laterally stiff, with a strong forward progressive flex. They can drive big skis at high speed. They are like slippers on the uphill. Light, comfortable, huge range of motion. No compromises. I'm on my third season with them, skiing 50-70 days per winter, 60% backcountry, 40% lift serviced. One of the best pieces of gear I have ever owned.

      Unanswered Question

      What is the difference between the Vulcan and TLT6 Performance as far as application? Why would I buy one over the other?

      Anyone know what the differences are (if any) between the half sizes and the full size?


      The half sizes and full sizes (27.0/27.5) will have the same BSL–all that changes is the liner/footbed.

      So, theoretically, the 27 would have a smaller fit than the 27.5? is the volume of the liner thicker in the full sizes?
