Hello and welcome to my Thirty Two Mullair review.
Note: Thirty Two have renamed this boot the 3XD for the 2021 model. However, in the catalog and at some retailers it's still being called the Mullair. So Mullair or 3XD, depending on where you get it.
In this review I will take a look at the Mullair (3XD) as all-mountain snowboard boots.
As per tradition here at SnowboardingProfiles.com I will give the Mullair a score out of 100 (based on several factors) and see how they compare with other all-mountain boots.
NOTE: The 2021 model was the last model of the Mullair/3XD, so this review will no longer be updated. The TM-Three 2021 and 2021 3XD have merged into one boot for 2022- the TM-Three XD.

Who are the Mullair Most Suited to?
The Mullair are best suited to anyone looking for a well built boot, with a flex just a little stiffer than medium, but not overly stiff, but still with good response and anyone who likes or is at least OK with traditional lacing, tend to need boots with good heel hold and wants something that has a lot of adjustability.
Not beginner suitable, but would work well for anyone intermediate and up, looking for a responsive boot that still has a good amount of forgiveness to it.
Quite pricey, so you also want to have a good boot budget for these ones.
The Mullair in More Detail
O.k. let’s take a more detailed look at what the Mullair are capable of.
Boots: Thirty Two Mullair 2020
Size: 10.5 (US Men's Sizing)
Date: February 10, 2020
Conditions: Sunny first thing, with some clouds later. But good visibility all day.
Quite cold. Not much wind, but what wind there was, was cold.
Hard packed on groomer with the occasional icy patch, but only in the shade and not many spots.
Off groomer a little crunchy in places but fine in other spots.
Bindings angles: +15/-15
Board Demoed With: Rossignol One LF 2018
Bindings Demoed With: Burton Malavita 2017
Outersole Length: 31.3cm (mondo 28.5cm)
Difference between Mondo & Outersole: 2.8cm
Backstay Height: 30.5
Weight: 1320 grams*
* Average of a sample of boots I weighed was 1006 grams, so quite a bit heavier than the average. These are the heaviest boots I've weighed and lightest were 740 grams.
They felt to me, just a little stiffer than medium, but pretty close to medium.
Width: They feel about average in terms of width in the toe box. Maybe just a hair wider than medium.
True to Size?: I rode these in 10.5s and they felt just right to me. I usually ride a 10, so I'd say they run half a size small - in other words you might want to consider going a half size up.
High or Low Arch: Medium to high. No pressure on the tops of my feet. I think those with high arches could get along with this boot. Of course, there is no substitute for trying on to make sure though.
Really good response - I feel like I could get deeper and longer on carves vs my test boots (Vans Aura) and more so than I would expect given the flex and feel.
And they're still good when it comes to maneuverability at slower speeds too.
Heel lift is very minimal in these boots as they are. But they also come with a heel hold kit that you can use to further they're heel hold if it's not enough for you out of the box. I was happy with how they were out of the box.
And that heel hold is achieved without massive pressure or discomfort around the ankles/heels.
These boots are really adjustable to suit your needs.
The traditional lacing offers great individualization of tightness across the boot - lower and upper and all things in between.
Then there's the aforementioned heel hold kit, to customize your heel hold.
In addition to that they also come with an arch support kit.
Let’s Break up this text with a Video
Really nice and comfortable boots, despite being quite heavy. You get a good snug feeling, but one that feels plush and without any major pressure points. All round I found them really comfortable.
They have a nice cushy, quality sole and that shows on snow. They have really decent shock absorption when riding.
Board feel isn't great. It's not bad either, but it's middle of the road.
The sole appears to be really high quality (which you would expect this price of boot, of course) and has good tread depth. Felt nice and grippy when walking in them and felt like the sole would last too.
They're not hugely reduced, but they're a little more low profile than the average boot.
It takes a bit of effort to get the foot in - and then the traditional lacing takes a bit of time/effort compared to other lacing systems, so not the easiest to get in and out of, but once you're in it feels nice and secure, but comfortable.
The inner lacing harness just has a nice solid feel to it as well - and it was easy to really crank it down, and do so without pressure on the foot/ankle.
Score Breakdown and Final Verdict
Check out the breakdown of the score in the table below.
TOTAL after normalizing
The Mullair (or 3XD depending on where you get it) feel like really well made, high quality boots - which they ought to be for the price. And the performance and comfort are right up there too.
If you can live with the price and the weight, these are really nice, high quality boots, that should be able to stay with you for many a season (depending on how often you ride each season of course).
Note: Thirty Two seem to have renamed this boot the 3XD for the 2021 model. However, in the catalog and at some retailers it's still being called the Mullair. So Mullair or 3XD, depending on where you get it. I suspect it will be uniformly 3XD for the 2022 model.
