Questions & Reviews

Question from Abc
Will the Alien 1.0 bushing work on the 3.0?
Answer from Gabriel I
Hi Abc, no, the Alien 3.0 bushing has a longer cylindrical shape and a smaller internal diameter.

Question from Thomas
I have a pair of Scarpa Maestrale RS boots from 2019 (the black/white/lime green ones). I need to replace one of the power straps as well as one of the whole cuff catch assemblies (cuff catch, screw, and nut). All of the parts listed here look a little bit different than those on my boots, I assume because they are meant for the newer models. Will they still work with my older boots?
Answer from Emmett I
Hi Thomas, all of the hardware listed on this page should work for your older model just fine.
Answer this question:

Question from Peter

I am looking for the same cuff screw and nut for Maestrale RS 2.0 that Emmett provided advice on in the comments above in 2023. However, it seems that the items that he specified are no longer listed in inventory. Can you tell me if the cuff nut and screw are now listed under different names?
Answer from Emmett I
Peter, we do have the screws and nuts in stock at the moment. The screw is on this listing (Maestrale/Gea Shell Cable screw), and the nut is available on our SCARPA Buckles and Straps listing, called Maestrale RS 2.0 Wave Cable Tongue Nut.

Question from Clifford
I am looking for a maestrale tongue hinge hold down. Do you have any in stock?
Answer from Teddy Young
Hey Clifford, it looks like SCARPA does not have any more Maestrale/Gea Tongue Hinges available for the foreseeable future.

As that tongue hinge design hasn't been around for a while, it's possible that we may not be able to get that part anymore. If that ends up being the case, we have heard of folks successfully doing DIY fix. A bit of sheet metal and a drill might get you up and running again!

Question from Jorgen Jalland
Hello Scarpa Team. I need replacement for Maestrale tongue hinges. Are they back in stock soon?

Best regards,
Answer from Lrow
Hi Jørgen,

Our buyer just verified it looks like that part isn't available for the foreseeable future.

Question from Nico Matallana
Hi there,
I have the original Maestrales and the outer cuff cant screw got stripped out. I'm seeing the Freedom Outside Cant Screw in your selection, is this compatible or should I look somewhere else?
Answer from Will McD
Hi Nico,
The Freedom Outside Cant Screw is what you need to fix that... mostly. I actually installed one of these on the exact same model of Maestrale this morning, and I found that I wasn't able to screw it in all the way. I fixed this by tapping the nut with an M6 1.0 thread pitch tap. If you don't have access to a tap, you can replace the nut with the Canting Nut that is listed on this page, which will also allow you to fully tighten the screw.

Question from Greg
The washer on the outer cuff popped off on both of my 3year old maestrales. Just want to double check which item those would be listed under?
Answer from Gabriel I
Hi Greg, that washer looks to be the "F1 Outside Cuff Washer" on this page. The same part number is cross listed on the Maestrale spec sheet.

Question from Darren

Hi Darren, we're out for this season but would expect to restock in the fall before next winter.

Question from Mike Curiak
I recently had a cuff pivot washer and bolt fall out while on a multi-day tour. Dohp. Apparently loctite and fresh torque are not enough...

They are the F1 Race (bellowed) boots. I see a few similar looking options in your dropdown, but it's hard to tell if the diameter/geometry of any of your offerings are correct for these shells. Thank you.
Answer from Jeff
Hi Mike, Yeah, tough to say. Can you email us at to help. Send us the diameter of the washer.
Answer this question:

Question from Will

Are you out of stock on the F1 Inside Cuff Nut?

Would the alien cuff nut work instead?

Answer from Jeff
Will, Yes we are out. It is a different part and I am going with no.

Question from Todd Dundon
I am looking for the screw & matching nut to secure the upper cuff buckle catch on my Maestrale RS 2.0's (indicated by the arrow in the photo). I think you may have answered this recently but I need to be 100% sure I'm ordering the correct parts as your shipping to Canada is extremely steep!
Answer from Emmett I

You'll want the Maestrale/Gea Shell Cable screw and the Wave Cable Tongue Nut found on our SCARPA Buckles and Straps listing.

Question from Dany
Do you have this part circle in yellow (see picture) of Maestrale 6-7 year old? thank's
Answer from Patrick C

Unfortunately, SCARPA is out of stock of this part and we are not sure when we will see more. If you send us an e-mail to we can set you up for a notification that will alert you when we have more Canting Cams in stock. Hope this helps!

Question from Jeff Hylok
I’m looking for inside cuff mounting hardware for a pair of Scarpa Freedom RS. any suggestions? I see various F1 and Alien parts which look close to the bolt and washes that I’m missing.

I can’t find the inside cuff hardware on the Scarpa site.

Answer from Jeff
Hey Jeff, We have it, it is the F1 parts
F1 Cuff Pivot/Freedom Buckle Ladder Screw
F1 Inside Cuff Nut
F1 Outside Cuff Washer

Question from Joe

I recently had the main pivot (outer cuff?) screw and washer disappear from one of my Mastrale boots. Looking at the other boot it seems like this is a silver hex cap screw with a special black washer. These are an older model from ~5 years ago. Do you stock replacement parts for this mechanism?

Photo attached.

Thank you!
Answer from Emmett I
Hi Joe,

You'll want the F1 Cuff Pivot/Freedom Buckle Ladder Screw and the F1 Outside Cuff Washer. SCARPA has a good amount of overlap with their parts.
Answer this question:

Question from Anna Trakhman
what all should I order to replace this missing piece? The backing plate is all that's left. These are a 2015 version of the Scarpa Gea RS.

-Looks like maybe a new canting nut (or not necessary)? I do have the old one, that's the only piece left.
-a canting cam
-but what about that larger missing ring? I couldn't identify a part which matched up that one but may be overlooking.

Also, would I need any specialized tools for this repair, ones beyond the basics in my toolset (wrenches, screw drivers, etc.) What kind of glue is best? Perhaps just loctite?

Answer from Tristan M
Hi Anna,

The parts that you need for a full replacement on the outer pivot point on the GEA are as follows:

F1 Cuff Pivot/ Freedom Buckle Ladder Screw
F1 Inside Cuff Nut (this is the part that you already have)
F1 Outside Cuff Washer

As for tools, all you will need is two allen wrenches and blue loctite!
Answer from Anna T
thanks so much for this quick reply, Tristan! One point of clarification -

As for the F1 inside cuff nut, this actually looks different than that backing plate looking part I mentioned was still remaining in the first post.

I couldn't add two photos to my original, so here's what I'm referring to:
It looks most like the Canting Nut, not the F1inside cuff nut.

Question from Jordan Delaney
Hi! Wondering if\when you will have any Maestrale tongue hinges in stock.
Answer from Jeff
Jordan, Skimo always has these parts on order. I just checked, and Scarpa is out for the foreseeable future. So I can't say when they will be back in stock.

Question from Nika G
Hi there,

I have lost cuff catch on my Scarpa Maestrale boots

I need to order it as soon as possible. I have found the exact catch but couldn't find it's nut and screw, not sure how it is listed above

Please tell me the name of nut and screw. Thank you in advance
Answer from Brett S
Hey Nika, for the screw you will need the Maestrale/Gea Shell Cable Screw. The nut for the older Maestrale boots cuff catch is actually the same as the F1/Alien 1.0 Ski/Walk Lower Latch Nut, which is in a different listing: SCARPA Ski-Walk Mechanism Parts. Hope that helps!
Answer this question:

Question from Jake D
If I want to replace all of the cuff pivot hardware on a pair of 2017/2018 F1s, should I be ordering 4x of the following?

- F1 Inside Cuff Nut
- F1 Outside Cuff Washer
- F1 Cuff Pivot/Freedom Buckle Ladder Screw

Answer from Brett S
Thanks for reaching out, Jake. You're correct!

Question from Paul Magnus Calabro
Hi SkimoCo!
Yesterday I broke the rivet that connects the cam hook for the laces on my Scarpa Alien RS to the plastic of the boot. I think I can probably get by with a hardware store rivet, but would just as soon buy the right parts...
I THINK I need the "alien RS rivet long, yellow... Does that seem right? Do I need another half for the rivet, whether it's an actual rivet part or like, a screw or something? The plastic housing looks undamaged, I just need to reattach that cam hook to the book shell. I'm happy to order a few parts and go with whatever works, if that's what you'd suggest.
Thanks SkimoCo! Love you guys/gals!
Answer from Jeremy L
Hello Paul! That is the rivet you need. It's just the single piece and you'd likely need a rivet press to get that in properly.
