SCARPA Maestrale RS 4.0 Boot
For a fresh hot take on the venerable Maestrale RS, the 4.0 model is redesigned with a more planet-friendly twist and different fit than its predecessor. Consistent with its environmental objectives, SCARPA is increasingly using materials made from renewable resources throughout its product lines. In this case, the cuff and shell are constructed with materials derived from castor oil, resulting in a boot that’s more sustainable to manufacture. Rest assured, these materials don’t cut corners and have allowed SCARPA to produce a Maestrale RS with the performance and durability of its predecessors whilst keeping its weight down. A confidence-inspiring set of 3 buckles combine to hold your foot in place and a dynamic power strap from Booster tops it off for a powerful and progressive skiing platform. Of course, it wouldn’t be a Maestrale without the generous range of motion and convenient ski/walk mechanism that the Maestrale is known for. With the RS 4.0, SCARPA is continuing its tradition of impeccably made ski boots that perform like the high-end Italian product they are.
- Carbon-infused Grilamid BIO and Pebax Rnew construction are more environmentally friendly without sacrificing performance.
- Speed MLT ski/walk mechanism is easy to use and allows for excellent power transfer.
- Wave Closure system securely wraps the foot for increased performance.
- HRS ankle strap keeps the heel locked down and not moving.
- The power strap has all the features you’ll ever need: it’s a dynamic elasticized cam-lock beauty made by Booster.
- Intuition Pro Flex liner is moldable and supportive.

The primary difference between the Quattro Pro and the current Maestrale RS would be flex and downhill/uphill performance. The Maestrale has a more touring-optimized buckle setup that should allow for easier transitions and weighs a bit less. The Quattro Pro is stiffer-flexing and more supportive, with a beefier liner and a stronger locking mechanism. It is meant for the most aggressive skiers.
Between the two boots, the fit of the shell is actually identical. The difference is that the Maestrale RS runs one full size larger than the Quattro Pro. For most people, we recommend your usual Scarpa size in the Quattro for a performance fit, and one full size down in the Maestrale to achieve the same. So for example, I would choose a 26 Quattro, and a 25 Maestrale for the same fit.
Thanks
I did not size up in the F1 GT for width but for length. My feet measure US 13
There are some similarities between the 4.0 Maestrale and the Quattro, namely the fit, but also the tongue - it is the same style tongue that needs to be tucked in under the cuff. I do think it is a little easier on the Maestrale than the Quattro, because the front of the cuff is smaller and easier to work with. The two boots use different plastics as well.
We have not seen any broken walk levers/shells in the Maestrale RS 4.0! It seems to be a pretty sturdy boot.
the walk mode its different, not the same lever. It also is a lot less faffy to get into. the receiving pin area that was breaking on people has been beefed up, its 24mm of material width now as opposed to 19. the flex is subtly softer but not much. scarpa has responded to most of your concerns with next years quattro pro. More cuff material that covers the tongue more, beefed up receiving pin area, beefier liner 130+ flex. Id imagine the annoyingness to get on is the same though. I havent experienced warping plastic so unsure on that regard.
As always try boots on, the best featured boot that doesn't fit well is useless.
I've found one comment about improved heel hold, which is encouraging as that is my primary issue with the fit of the 3.0 and 2.0
The fit of this boot is very similar to the Quattro, but larger, for the same mondo size. We believe they are molded from the same last. Compared to the older Maestrale 3.0, this means less volume on top of the foot, and a narrower mid-foot and heel area. The forefoot may be a bit roomier laterally, but is certainly lower volume vertically. But for the same mondo size the new Maestrale may also feel slightly bigger. If your primary issue is heel hold, it might be worth trying the new boot as it has been reworked substantially!
With 27cm feet (more like 26.8 with footbed aupport I should belong in 26.5/27 shells, right? Thanks!
So if you were a 26.5/27 in another Scarpa boot, yes, I would go with it again.
Obviously this always depends on the individual's foot size and shape, but I'd like to know if they have a similar internal length.
When doing a shell fit, I find that the gap behind my heel more closely corresponds with BSL and not mondo. Thus, in the case of these two boots, the BSL is a better indicator of internal length than Mondo.
You are correct with the bsl difference between the Maestrale and Quattro. I apologize, my mistake. In general however, BSL is a not an indicator of fit. Take this boot in a size 24.5/25 for example. Folks who feet measure 29cm or 290mm (the BSL of a 24.5/25) in length would find this size ~4cm too short. I apologize for any confusion with my mixup! Thanks.
I found this video online to be helpful before I pulled the trigger:

There is quite a bit of redundancy in having both boots, but for me the 4Quattro is a great option for the resort (with kids) and for traveling with one pair of boots, while the Maestrale will be purely for touring/ski mountaineering.
Hope this is helpful.
Some good discussion here. Certainly some learning for me too with these new boots. After some deeper investigation, it appears the lowers of both the new Maestrale and Quattro are molded off the same plug. That is where the similarity of these boots end however. They have different liners, plastic, buckles, etc. This is also somewhat of an an anomaly when it comes to sizing based off mondo. In regards to length alone, if you find a good fit in a 27 SCARPA boot, you may find a good fit in a 26 in the Maestrales. Again I apologize for any confusion and thanks for sparking some research!
You are correct, no dedicated leash attachments. You could clip a leash to a buckle or install something, or use a wrap-around leash that clips to itself. But no specific attachment for leashes from the factory.
