Preview: 2025 Lange RS Boot Collection

Collimg.jpeg

Crab cakes and football, that’s what Maryland does. Well, blue boots and racing are what Lange does. There is a long established history of Lange and racing and, while they have had race boots in various colors such as black, yellow, orange, pink, and of course, purple haze, it is the blue boot that people recognize today as a Lange race boot. It is nice to see Lange come back to a medium blue from the dark blue which IMHO was a slight misstep.


In the past 15 or so years, Lange’s blue RS boot was the boot that many high performance skiers sought out. It was also one of the few products on the market that ski shop customers demanded, and would walk out if the shop didn’t carry it. For those skiers, there was no substitute. Until this past season, the RS collection shared its architecture with its brother the RX. This season, the RX was replaced by the Shadow series of boots. That change took the reins off Thor Verdonk and his team, allowing them to ramp up the horsepower and create an all new and higher performance RS series of boots.

Lange has long offered a halo World Cup collection for the racers of the world. They never offered a flex number, but instead used letters ZA, ZB, ZC and ZJ with the C being the stiffest and the J for juniors and women. All skiers looking for a solid lugged boot with a lace up liner were served well by these boots which had one simple purpose: to be efficient and fast. One of the ways the boots are efficient is because the shells were shorter than their retail RS counterparts by 3mm. Whereas the RS (and RX) series were based on the 6s in millimeters (25.5 was 296 mm), the Z boots were on the 3s, so the same 25.5 was 293 mm. While that does not sound like much, it is millimeters that can define a boot design.

Now, it can rise to its rightful place close on the heels of its 92mm wide, solid lugged real racer brother, the Z boot. Now, all of the RS boots are also solid lugged which creates a better connection to the binding and thus the ski. The RS collection will still be offered in a 21.5 short cuff version (but in current 261 mm shell), all the way to a 120 flex! Most of the models will still be offered in a narrow (97 mm) and wide (100 mm) width. Whereas the old RS’s 100 mm offerings came with replaceable soles like the narrow versions, these are now solid too. More on the wide version in a bit when we talk about fit of the boot.

Rarely do we ever talk about aerodynamics of boots (we do not have any discussions on what wax people should use to make their boots faster) but, when races can be decided by hundredths of a second, a more slippery boot can add to that advantage. It might mean the difference between first and second or between third and not reaching the podium at all. Working with Formula 1 Sauber-Alfa Romeo Racing team, Lange is making a more streamlined boot with their AeroFlow shell.

Connecting the cuff of the boot to the lower (clog) is key to power transmission. Lange has designed a new Race Flex Adjuster with two options included with the purchase. A PU+Injected Carbon for the most direct energy transmission and a PU53 which can decrease the stiffness by about 8% without the loss of energy are in the box. Skiing the boot on hard snow with both, the difference is noticeable. Without having to go to the World Cup boot, a skier can experience increased performance. Lange will continue to use their very good DualCore which does help keep the flex on the boot very consistent in varying temperatures.

Consistent with other Lange offerings, the RS’s stance has a 4° ramp in the boot and a 12° forward lean, but actually feels more aggressive than the published number. A significant spoiler is included for those of us who like a little more aggressive stance and/or have chicken legs and need to take up some volume. Out of the box, the RS is set up at a 1º positive lateral stance for additional energy transmission. With Lange’s commitment to stance alignment and canting, any bootfitter worth their salt should check alignment with every skier who commits to the boot.

While many boots claim to be “bootfitter friendly”, the Lange RS is definitely one that is more friendly than most. From the ability to adjust flex, a zeppa (boot board) with marking if it needs to be flattened, dual cuff alignment, and fully removable buckles, the Lange offers a wide range of adjustability. I like the solid lugs for the ability to cant the shell and the numerous sole options.

Let’s talk about fit, my fit. I have been skiing low volume shells for as long as I can remember. I have a narrow heel with an average forefoot. In some cases I have to do a first and/or fifth metatarsal punch to accommodate my foot. In the new RS I actually opted to go for the mid volume version! I know, sacrilege, but before you completely condemn me, hear me out. Lange designs their low and mid volume boots with the same snug heel but different forefoot widths. This allowed me to just to slide into the 130 MV with little or no work whereas when I tried the LV I knew I would have to do work to the shell. My point is, leave the ego at the door and don’t dismiss the MV if you usually have to do work to an LV, because the back half of the boot is superbly low volume.

While we are on boot fit, we say that a millimeter is a mile. The roof of the new RS is a mile and a half (1.5 mm) lower than the outgoing model. I like that, but @Tricia, with her surfer's knot on the top of her foot, not so much. Since she has moved to the Shadow, this should not be an issue for her. Again, another aspect of the new design that moves the RS closer to the World Cup models.

I have said this about a few reference products, but when you have a target on your back, it is extremely difficult for your competition when you keep moving that target. Lange has been adept at moving that target for as long as I can remember.

Great overview, Phil.

Haven't got the opportunity to view the video, so forgive me this; is the MV the same instep height and cuff circumference as the LV?

Cheers!

Yes it does.
 
Jim Lindsay said that next year's RS130 MV will have a solid sole.
I did say all the RS's have solid soles/lugs...

"Now, all of the RS boots are also solid lugged which creates a better connection to the binding and thus the ski."
 
Wow. Will have put both on my list for boots to try on for bootfitting season.
I was very surprised that I ended up in the MV, it shows the commitment Lange made to this series to not just be a big step down from the World Cup collection but a viable alternative for those who cannot get into a 92 mm shell.

Very interesting option, suddenly. My ideal boot would hug the crap out of my heel and ankle, with a semi low instep and give my bunions room to breathe.
 
Intriguing boots and great write up. Thanks! The lower instep is likely a deal killer for me. Wondering if they use the silicone instep flap of the previous RX to aid getting in and out?

Instead of aero enhancement, I'd like an air brake feature so I could do more pure carving as my knees age....... :ogcool:

REALLY looking forward to hearing a lot over the next year on how the new RS compares to the new Shadow.

But great for me, to each their own and that is why there are many boot options

Not there. More no frills.

Where the RX and RS used to be similar, the Shadow and the RS are very different.

Seems like a similar design approach to what Atomic did with the Redster Club Sport in terms of a viable alternative to a 92mm shell.
 
How does the ankle area and heel pocket width / volume compare to the current RS?
Using the unscientific "fist" method, the new RS MV feels narrower in the heel than the outgoing LV model

Any word if the Lange World Cup RS (92mm) range is being updated? Or only the RS 130/120/110, etc.?
 
@Philpug The opening sentence on the home page is fire!!! Love it.....like a hungry bass it lured me in I came for the sizzle but stayed for the steak. Great assessment of the RX line....have been wondering what direction Lange was going with the RX line and this article answered it.
 
I've been skiing in Langes for many years. I have a low volume foot, 96mm across the forefoot.
I have skied the RS in a 26.5 LV for years but now, due to Plantar faciaitis have to wear a 27.5. I presume,hopefully, that the shortening of the new RS only applies to the sole length and not the interior length of the boot.( i.e. a new 27.5 is the same interior length of the old 27.5.)
One of the main reasons for skiing in the Lange RS was the new shape of the toe box about 10-12 years ago. It configures well with my toe's shape and their length. They allowed me to ski in the 26.5 LV.
I have purchased several different boots in the last 2 years trying to stay in the 26.5. None had the toe box that would fit my foot. I do hope, that since many of us "ski" with curling our toes, they didn't alter the toe box(height) too much!
The lowering of the instep height should benefit me due to the drop of my instep due to the Plantar faciaitis problem. I already purchased a pair of Shadows but the fit was not good in the instep, so we parted company.
In your reply comment to Tom K., referencing putting the boot on, am I to understand that the step in ease of the new boots are more difficult than the prior RS. I ski in Zip Fits which work very well for me but it would not be good if the new boots make it more difficult to use the "World Cup method" for putting on my boots
I have wondered, for the last two years, if Lange would be aware enough, about what a great color they had used for years, to return to it!!!
Thanks for your efforts Phil!!!
