  Size Chart

If Dynafit made a Venn diagram of its (non-race) ski boot lineup, one circle would feature the beloved TLT8 Expedition boot, known for being lightweight, efficient, and capable of big days in the mountains. The other circle would be the Hoji Free 130 boot. These aggressive, huck-your-meat, stiff-as-a-2x4 boots have proven to be a delight for the freeriders who earn their turns (and drops.) But what about the skiers who want a little A and a little B? What would be the overlap of this Venn diagram? Introducing the Dynafit Radical Pro boot. This factory-made Frankenstein keeps the best traits of the Hoji Free but goes on a diet for a faster up. Don’t worry, the ingenious Hoji Lock System isn’t going anywhere. With one simple movement, you can switch your boots from a rock-solid stiff alpine boot with a 120 flex to a comfy, nimble 60 degrees of cuff rotation. The Master Step insert makes clicking in even easier. The cuff is Grilamid loaded with glass fibers for weight savings and increased durability. Speaking of up, the Radical Pro features heel and toe welts capable of accommodating step-in crampons. Once you’ve breezed to the top, just hit that same lever again to reverse course, and charge the mountain. The Dynafit Radical Pro allows you to bask in the glory of a great performance on the up and the down.

  • Ingenious Hoji Lock system transitions from climb to descend with the flip of a single lever.
  • Dynafit Ultralon liner walks incredibly well when combined with 60 degrees ROM.
  • Master Step insert makes clicking into your toe piece a breeze.
  • 120 Flex makes this a hard charging, confidence inspiring piece of footwear.
  • Pomoca outsole provides great grip to keep you upright on that ice-covered ridgeline.

Update 2023/24: Dynafit has introduced a new color palette but the boot is otherwise unchanged.

Question from David
I wear Fischer’s in 28.5. What size your you recommend?
Answer from Gabriel I
Hi David, we prefer to defer to your measured mondo size, and also like to ensure that the boots we recommend are the right shape for your feet. The best way to do this is to fill out our Boot Fitter, and we can start a conversation from there!

Walter (used product regularly)
Great boots, but there is a big but! The strap holders have a very poor design. They are too little and too thin to withstand the body weight pressure during the descent. The plastic gets firmer in cold condition and the result that they broke off at my second day….this way the straps do not stay in place and these boots are a thumb down for me!

Question from Jason
Any speculation on if Dynafit will make an Extra Wide version?
Answer from Lrow
Hi Jason,

As of today, unsure, I will say if the 103mm stated last for the Radical Pro feels too narrow, there is quite a bit of modification we can do around the toe box because of the thicker materials.

We do have the TLT X extra wide at a stated 107mm last, and it is wider throughout the boot, not just the toe box. Some modifications can be done as well but the grilamid is thinner. That might be an option for you if you're looking for a touring boot that's not as beefy like the Radical Pro.

Joseph S (used product a few times)
I bought a pair of the Rad Pros from SkiMo and have had them out 10 times getting the boot fit right.
They ski well and easily handle the tough conditions and lift ski alright too.
Compared to my Hoji Free boots they are a tad more upright, less forward lean, but seem to ski nearly as stiff. I had to adjust my skiing a bit for slower tip response time, but they rip!
I got them for my wider foot, I’m a tweener, with neuromas so I had to modify the boot, add a board to take up slack.

The one real disappointment is the liner.
The toes on the liner taper down at the toes and don’t have the boxed toe area to allow more toe room. Super disappointing Dynafit went with this design.
I went from a 29.5 to a 30 shell to get more toe space, and I have less toe space because of the tapered liner…with a 6mm longer shell!!
Also the Rad liner says 30, but it’s the exact same length as my 29.5 dynafit Vulcan liner.
Happy I had a pair of unused 29.5 Vulcan liners with boxed toe area I can swap out.
More fiddling with the liner fit and it will be a winner!

Question from Kenneth Berger
Is it dangerous to use these boots in a Gripwalk (but not MNC compatible) binding?
Answer from Emmett I

These cannot be used with gripwalk bindings, the toe won't interface with the binding properly.

Question from Federico
Hi guys, anyone using the Radical Pro with skis >110m ?

I usually drive a kastle tx103 and for that their gonna be fine. But I'm wondering if I will be able to enjoy the powder days driving my k2 116 with these boots as well.

Thanks a lot !
Answer from Emmett I

You shouldn't have any trouble driving a 116 with the Rad Pro, especially on pow days. Some very aggressive skiers might find they want more support on variable/crud days, but overall the Radical Pro would be fine for a 116.
Answer from Alex
They're just fine with Lotus 138s
Answer from Joseph S
Agreed with the above. I’m 6’4 210#
Aggressive skiing old man. I was able to easily power 186cm 124 waist Volkl BMT with Kingpins yesterday in boot deep PNW soft snow, I had my doubts but the shined. Best worst snow I’ve skied in years!
I’ve skied them on my 88 waist skis as well. They are not Downhill boots, but the do the job.
Answer this question:

Question from Andrew Wagner
Hi guys, I just got a pair of these and they seem like the best touring boots ever. And they mostly fit great out of the box which has never happened to me before. The one hot spot is over the ankle. In walk mode the inside edges of the lower cuff seem to pinch and dig into the top of my ankle/bottom of my shin. It looks like it would be an easy fix to grind it back there a little bit and shouldn’t affect performance. Actually the way the plastic is molded it’s thinner there almost like they intended that to be a potential fit mod. Just wondering if you guys have dealt with that or have any suggestions.
Answer from Emmett I
Hi Andrew,

I think you could grind a little of the edge material and it wouldn't hurt the boot - although I wouldn't want to make any promises about the warranty. Before removing material, I would try heating the area up with a heat gun (carefully - you don't want to bubble or melt the plastic) until it's pliable and then press those edges out a little by hand to enlarge the ankle area slightly. I did a similar modification on my Dynafit Hojis and it worked well - the ankle pocket was just a bit snug out of the box.
Answer this question:

Question from Jenna
Hey there! Is there any difference between the Dynafit Radical men's vs. women's boots (other than colors)? My Dynafit TLT8 women's boots that I bought last year are 26.5s that flared up a neuroma that took me out for most of last ski season (boo), so I'm thinking Radicals in 27?

Answer from Carlos M
Hi Jenna,

The TLT8 would be a similar fit to the Radical in the sense that it is wide and high volume. However, sizing up may not be necessary if you can identify the problem area and punch the shell - the Radical takes a punch very well. If you'd like to discuss your boot options in depth, fill out our online boot fitter.

With regard to men's vs women's, the difference is that the men's comes with the removable spoiler installed in the back of the cuff. This increases the lean a little bit and takes up some space in the calf area. The women's version lacks this, to make space for a relatively bigger calf muscle that might come down lower.

Question from Ezri
I currently have a pair of Hoji Free 130 but find that there is not enough instep space for my left foot. I have narrow feet but apparently my instep on my left foot is large. I'll be returning the pair and I'm looking into the Radical Pro instead. Would the additional instep space in the Radical Pro warrant the purchase?
Answer from Niko M
Hi Ezri,

The Radical Pro does have more instep volume than the Hoji Free 130 - quite a bit more. It is also wider. It would definitely ease pressure on your left instep, but if you have narrow feet it might be a little too wide. Shoot us an email at and we can help you get into a better-fitting boot!

Question from Brent
I am currently in a Dynafit Mercury 27.5, that fits well. Do these run a little bigger or would I be good to stay 27.5? I know shell size is the same, but boot sole length is slightly longer. Wondering if I should go down to a 27 liner.
Answer from Gabriel I
Hi Brent, these run true to size, I'd opt for the same 27/27.5 shell you currently have. Note that after a heat mold, the 27 and 27.5 liner are going to fit exactly the same.
Answer this question:

Question from William
Is the only difference between the 26.0 and 26.5 sizing the liner? Or is the shell also slightly larger?

Hi William, those sizes use the same shell. Only the insole thickness is varied.

Question from Al T
Can you contrast the TLT 6 vs the Radical Pro? WT, flex, downhill/uphill performance, warmth etc? Thanks
Answer from Jeff
Al, In every respect, these boots are different. The TLT 6 is light and narrow low volume fit. The Radical Pro is currently the widest and highest volume boot we carry. And the Radical Pro is a much stiffer more DH boot.

Answer this question:

Question from Peter
does anyone know hot to reduce flex, when the boot is really cinched down in the upper shaft? I have skinny ankles and calves, I even flipped the upper bucke 360° to cross the buckle cables to make them shorter. But with that the boot feels like beiing from concrete. If I loosen it a bit, it regains its flexibility. Maby shaving some plastics, but where exactly? What are contributes the most to the stiffness of the boot? Thanks
Answer from Emmett I

If you haven't already, make sure the cuff catch is in the tightest position. As far as lowering the flex goes, there's not much you can do, and probably nothing that wouldn't void the warranty. If you were to grind the plastic down, I would guess that grinding the front lower part of the cuff would help soften the forward flex, but that's a total guess.
Answer this question:

Question from Chris
What are the differences (besides flex) between the Radical and Radical Pro? I'm skiing the TLT8 Exped and I'm looking for the next step up in performance and stiffness.
Answer from jbo
Hi Chris, you've found it! The Pro version has the "pants down" Hoji lock system, whereby one motion changes the lock lever, the upper buckle, and the power strap tension so you don't even need to lift your pants when transitioning. The lower-end model has those things separated so it's more fiddly.
Answer this question:

Jonah Davis (used product regularly)
I had been searching for a AT boot that works well for my feet and gives all day comfort. I have very high arches and the the instep volume is great in the Radical Pro. My feet are medium with, so the Radical Pro is a wide in the forefoot for me. That said, I also have Morton's neuromas in both feet, so I really need to sacrifice some performance fit there for the all day comfort to avoid aggravating the neuromas, which can be excruciating. The width and relatively wide toe box of the Radical Pro fits the bill (sorta like an Altra running shoe but in ski boots). They give give me all day comfort with little to no aggravation of the neuromas. And then volume of the boot accommodates metatarsal pads on an insole, which is great and helps give an even more secure fit in the ankle and rear of the foot, making up for a bit of the spaciousness in the toe box area.

Skis great. Walks great. A bit on the heavy side but it's a beef boot. Hoji lock system is really slick. Sometimes a bit tough to get the boot lean properly aligned for the transition, but overall not bad and something you get used to.
Comment on this review:

Question from Ian Wyant
Considering making the switch from Maestrale RS to this boot due to needing a larger instep to accommodate my towering arches. I'm comfortably a 26.5 in the Maestrale, but found the Radical Pro to fit a bit snug in a 26.5 and a bit loose in a 27.5. What's experience been with getting this boot to accommodate feet that are between sizes? Should I plan to size up or down?
Answer from Emmett I

Keep in mind that the Radical Pro is wider throughout the forefoot than the Maestrale. You could consider the Lange XT3 Tour Pro, which has lots of room in the instep but not as wide of a forefoot as the Radical Pro. SCARPA uses slightly offset sizing. I'd recommend filling out a Boot Fitter so we can get you the most specific recommendations!
Answer this question:

Cyw (downright abused product)
First off: I have very high volume feet. They make boot fitters sad. Wide forefoot, high arch, high instep, fat ankles, average heel. My feet hurt in most touring boots, no matter how much punching and molding I get done. So, when a buddy told me these boots fit "like an airplane hanger" I was intrigued. No, they're not that roomy (luckily) but they do fit my weird hobbit feet better than anything else I've jammed my foot into. They fit fine, with no punches, a first for me! As far as the other important things: They walk well, although they have a little less rearward ROM than I'm used to from this class of boots(Maestrale RS feels like it has a few degrees more). I love how quick and simple the buckles are to use, and how smooth transitions are. They ski better than they should. Not the stiffest boots around, but the flex is super smooth and predictable. This is the first touring boot that I've ever been happy to ski everyday inbounds. I've swapped a booster strap in for the velcro top strap, and use Intuition Tour Wrap liners. The stock liners will probably be good for most folks, but for some reason my weird sensitive feet get along better with the wraps. No durability issues after 50-60 days skiing them. Big fan of these boots as a do-everything boot. If Dynafit came out with a stiffer and heavier, or a softer and lighter boot with an identical fit, I'd buy them in a heartbeat for inbounds days, or big objectives respectively.
Comment on this review:

Question from Scott Shatalow
Time to replace the good old Vulcans. Would the Radical Pro be a logical replacement boot? Spend most of my time touring, but still ski the hill with the same boots. The Vulcans did the job very well. Any info is appreciated.
Answer from Tristan M
Hi Scott,

Short answer, the Radical Pro is a solid replacement option for the Vulcan.

The details: The Vulcan had a higher volume fit. In the Radical Pro, Dynafit has also opted for a higher volume fit. This boot has a wider last width, and fairly roomy instep. For a freeride boot, the Radical Pro is lightweight and sports a large ROM, while packing a punch on the way down. It is a good option if you are trying to split the difference between inbounds and backcountry skiing with one boot.

Keep in mind that the fit of a boot is paramount, not just the performance characteristics. If you have more fit questions, I would highly recommend filling out a boot fitter.
Answer this question:

Question from Eduardo
Is the forward lean adjustable on these boots? Also do you have a user manual or PDF showing how to make these changes?
Answer from Gabriel I
Hey Eduardo, the forward lean can be set to either 15 or 11 degrees by removing the spoiler.

There are two removable T20 torx screws with t-nuts on the back of each boot that attach the spoiler. One of the screws also holds the power strap on, so you may want to flatten the t-nut spikes on that side when you reinstall it to avoid piercing the strap at the attachment point.
Answer this question:

Question from Kellan
I have a pair of intuition pro tour liners that I had molded and wore once in another pair of boots. Would those liners be an upgrade over the stock liner in the radical pros? I feel like I should use the intuition liners but hate the k2 a that I put them in. I have about 5 days of backcountry and 20 days of resort skiing on my dynafit liners.
Answer from Cole P
Hey Kellan, the Radical Pro stock liners are made of the same material as Intuition liners so there are only an upgrade if it changes the fit to your preference. If you rather use the Intuition liners they will work fine in the Radical Pro. I suggest re-molding them or expect a few days of skiing to break the liners in to get the desired fit.
