Salomon S/Lab MTN Summit Boot
“To get down, one first has to get there.” This sage observation from an unnamed but exceptionally handsome staffer here at Skimo Co sums up the age-old conundrum in the backcountry community. That is, one must earn their turns. To help make the battle against gravity less lopsided, Salomon made the S/Lab MTN Summit. Utilizing an Ultramid + shell with a carbon fiber-charged spine, the MTN Summit is more than ready for that long slog to the top and demanding descent through variable snow. Featuring an innovative Touring Belt, the MTN Summit can keep its pants on while providing an adaptable heel lock, reducing blisters and increasing skiability. Trying to lessen their environmental impact, Salomon uses 30% recycled material in the outsole to accomplish that goal without impacting durability or functionality. From galivanting to distant peaks, lapping your favorite powder stash, and everything in between, step into the MTN Summit.
- Custom Shell HD allows for full customization of the shell for an unparalleled fit.
- 70° range of motion is ultra-flexible, letting you skin to your ankle's content.
- Touring Belt provides exceptional heel hold, helping reduce problems with blisters.
- Surelock Ski Walk Mechanism is easy, unobtrusive, and offers a progressive flex.
- Adjustable forward lean lets you dial in your stance.
- Outsole is made with 30% recycled material.
*Not compatible with Alpine-heel touring bindings (e.g. the Shift, Tecton, or Kingpin).

Would these be beefy enough to drive my my atomic backland 107s 182cm with dynafit st rotation bindings? Im 6ft 165lbs. I have tried them on and they fit and walk like a dream, but I'm wondering if they would pair better with a smaller ski.

Hi Sam,
Good question! We find that these can be a great combination with wider skis in powder conditions (super efficient for many laps), but may start to struggle when the going gets rough or firm. The more forgiving the snow, the better the combo will be, but if you are looking for the perfect pairing for that ski in all conditions, you'd probably be better off with something a bit stiffer and more substantial.

I have these boots, generally really like them though find that the liner is not high enough volume for my shin/calf. I have to crank the Velcro buckle to feel locked in. What liner replacement would you recommend for this boot that will take up more volume so I don't have to crank down the shin so tight? Thanks.

Hi Patrick,
I would try a 9mm Intuition Tour Tongue or a Palau Alltrack Power MV! The Intuition is slightly thicker and the Palau walks a little bit better. Both will fill some space in the cuff (and lower shell) compared to stock, and with a heat mold, should fit well.

I appreciate the feedback. I currently have the Palau tour lite in the boot and I added high density foam to the shin to take up volume but it's still not enough...
Any thoughts on the intuition tour wrap?

Answer this question:
These boots walk incredibly well and Salomon did some wizardry to get those pivots truly frictionless. But those frictionless pivots are also the downfall of these boots. After a season putting 500 miles and 275k on these boots, the pivots are cooked. There's a lot of play at the hinge point that bucks me in the back seat when skiing through inconsistent snow. Putting in a beefier liner can help with this but still don't ski the same way they did out of the box. I replaced these boots with the Dynafit Ridge boot.

Hi there!
I still can't for the life of my understand the forward lean. I loosen the screw but simply flipping the plate upside down doesn't make sense or seem to change anything, how you confirm the boot is in 13.5 or 16.5 degrees of lean? Any detaul would be appreciated! Thanks!

Hi Josh,
You have it right - you change the forward lean by flipping the plate. It has a small plus on one side and a minus on the other side, to indicate which setting is which. When the plus is on top, you are at the steeper forward lean angle. When the minus is on top, you're at the more upright setting.

How is the fit of this boot relative to Radical Pro 28.5? I like the fit of the pro but looking for a lighter boot. Pro is 1600g in 28.5.

Hi Paul,
These will fit a bit narrower and lower volume all around compared to the Radical Pro. Length wise they will be very similar. Fill out our Boot Fitter and we can get you some recommendations.

I've had these boots for a few months and they have a little play when they are locked down. There is a bit of movement in the walk mode mechanism that isn't present in my older mtn lab boots (the rectangle cutouts in the walk mode plate seem a little oversized?) as well as 1-2 mm of play in the bushings on the pivot points. It translates to a few inches of knee movement back and forth. Im not sure if you can send new bushings but I think a new walk mode/forward lean plate might solve half of my issue. Is that a spare part I can buy?
I was expecting a little wiggle but my other boots (same Salomon walk mode) are so solid this is worrying to me.

Pretty good, the best skiing tongueless boot I've had. I ski them with 1700g skis as my daily drivers
The good: very svelte, walk lever/mechanism is the best I've tried being almost all internal it never fails or "misses". Buckle does a nice job and is placed well. Im very surprised how durable they are, after two days of scrambling in other boots they look abused. I don't know what's different but for some reason these just aren't getting beat up like other boots.
The bad: the boa. Can we stop it with the boas? A gentle, comfy grab of the foot is not what I'm looking for dropping into a steep icy line. The "touring belt" is functionally useless in my experience. An instep or spider buckle would GREATLY improve this boot
despite my boa hatred I always pick the MTNs over my heavier and lighter options which have gathered dust for a year now

How does the cuff height compare to the Atomic backland carbon?

Hi Peter, they are very similar. The cuff pivot location, total height, and liner height are just about equal on both boot models.
Answer this question:

When this boot says tech only bindings, does that include bindings like the Tecton or is it heal pins only?
6/24/2024
Hi John, "Tech Only" binding compatibility means that it only works with toe and heel pins. The specs will say "Hybrid" if a boot works with Tectons and similar bindings with tech toes and alpine-like heels. The Salomon MTN Summit is not compatible with Tectons.
12/30/2024
so I cant figure out why they arent compatible. Toe toe part works (obviously) and it looks like the heel has plenty of lug to engage with. I tried stepping in and everything seems jolly but I haven't tried to ski this way (and am a little afraid to do such)
12/30/2024
Hi Jason, there is a grey area with non-9523 boots. Fritschi does not endorse this boot as compatible within that grey area...6mm of heel-welt depth is one requirement. They recommend the Vipec Evo or Xenic.

I honestly don't understand how humans get their foot/feet into this boot. I tried and tried and simply could not get my foot inside the boot. I'm 38, fit, good ankle flexibility, narrow 95mm wide foot and skinny calves, and I was genuinely fearful I was about to seriously injure myself trying to get my foot past the throat/neck of the boot: it is such a small opening and the shell surrounding said opening is insanely stiff. The boot fitter at the Salomon store in Chamonix was unable to make it happen either. This was at 70f room temperature mind you. He metioned that lots of people can't get into this boot. The experience left me drenched in sweat and positively baffled. What are alternatives in this boot class that regular people can actually get on their feet?
4/16/2024
Hi Drew,
Not entirely sure what the problem is, but I've never had issues taking that boot on and off (and I also have narrower feet and skinny calves). My recommendations would be to ensure that the boot is in walk mode before you try to put it on, open it up all the way, and if all else fails, you can also try using a plastic boot horn.
With narrower feet, this may not be your best boot anyways - it fits a bit wider in the forefoot, and is a bit higher volume. I'd recommend filling out our boot fitter so that we can get a little more information and recommend some models!

Could this boot work for someone who fits best in a low volume boot? It doesn't seem like there many narrow/low volume boot options in this category.
My touring boots right now are Hawx XTD Ultra 130s but looking for something with better ROM and a bit lighter for long days in the hills, these seem great but worried about sufficient heel hold and too much room in toe box . Long skinny foot and ankles, medium instep.

Connor,
Fill out our boot fitter form and we can get you some personalized recommendations!
In general, this boot would work well for someone with a lower volume boot. More of a medium to low volume fit. Something like the SCARPA F1 XT would also be a good option. Narrow forefoot, moderate instep.

Hows the heel pocket compare to the Atomic Backland Carbon from 2021? Can you punch the heel pocket if need be?

Hi Josh,
Yes, you can punch the heel pocket a bit. In general, this boot is pretty easy to punch. Compared to the Backland Carbon heel, this one might be a little narrower.

Any experience yet with punching this plastic before or after shell molding?? I'm a size 12.5USM or 30.0mondo, with a wide midfoot and wider yet toes. I currently sport an extremely punched S/labMTN 29.5 which barely fits. (And a slightly punched Mach1HV for alpine). I love the shape and features and flex of this new boot, but trying the size 30/5 felt small on my foot in every dimension including length. Based on the shell molding and punching potential, would you say this is a boot which can be made to work from a tight box-fit?? Thanks in advance!
12/9/2023
Joe,
If it hasn't been molded, it can be punched fairly well. After molding the shells, they can typically still be punched a little bit, but depends on how much they were stretched in the molding process. Very situation dependent.
As for the fit, shoot us an email at help@skimo.co. It might work, but there are probably options that are closer out of the box.

Hello SKIMO Team,
I already have this boot paired with Salomon MTN 96 skis and what a blast! I am looking to purchase a new set of powder skis to pair with this boot. What are your thoughts of pairing this boot with the Voile Hyper V8? Am I asking too much out of the boot? The pow I envision is Montana cold smoke
Take it easy,

Hello Tommy,
Based on most manufacturers or reviewers of Beefy touring gear, no go.
That ski in just Sweet Pow and a finesse skier, it can work.
I use my Alien RS boots on some 112mm Powder skis. Only a few times, but works fine. If you have long and rough exits, you may get tossed around a bit.

I've had these boots for a few months and they have a little play when they are locked down. It seems there is a bit of movement in the rear flipping mechanism as well as a mm of two in the bushings on the pivot points. It translates to a few inches of knee movement back and forth. Can you tell me if this is to be expected? Salomon customer service is not much help. I don't remember this play when they were brand new but I could have just missed it.
3/16/2023
Hi Brent, we've found maybe a millimeter of movement in the rear walk mode lock, but the bushings should be pretty solid. This translates to about an inch of fore/aft knee movement when rocking back and forth when I wear them. This amount of movement isn't unusual for this style of walk mode that locks within the shell.

I'm confused by the "99/105", can you explain? Thanks!
2/3/2023
Sorry Rudy, I cannot explain! Potentially it's the width measurement at a couple of different spots in the boot which reveals the underlying issue with listed lasts: no two manufacturers measure the same way so they can be quite misleading. We don't bother putting this somewhat random number in our specs. It's the same story with "flex rating". We recommend visiting our boot fitter for the skinny on how various boots might actually fit you and perform.

JBO, thanks! Very interesting.. what a wacky system, and I’m grateful you all are here to help.

Stock, It’s a 99mm last boot. Salomon’s Custom Shell molding let’s it stretch up to 105mm.

That makes sense, Eric! Salomon says there is 6mm of expansion possible. As for the 99, not sure I would call it that.
