Sharing a look behind the scene of manufacturing the world’s lightest ski boot (Pierre Gignoux 444 model) through the eyes of Michael Silitch, an internationally certified mountain guide living his dream in Chamonix.
Both of them ski the PG boots on regular basis while Nina is also putting them through rigorous testing on the skimo World Cup circuit.
On behalf of all SkinTrack readers I want to thank Michael for sharing his experience from a visit to Pierre Gignoux’ workshop.
Michael supplied the text and photos, so please contact him via his website if you wish to reuse any of it.
Also, judging based on Pierre’s accomplishments as a ski mountaineer, and couple of reports like Micheal’s, Pierre is an absolute representation of someone extremely dedicated to deliver nothing less than the best to the sport he loves so much.
For a comparison of the lightest ski boots, currently available on the market, make sure to read also check these two articles and great discussions in the comments sections below them:
Look behind the scene – Michael Silitch words
Nina just loves her Pierre Gignoux all carbon fiber ski boots. She loves how light they feel climbing (less than 10% heavier than a Salomon World Cup nordic skate boot) and also how stiff they feel while descending, delivering precise edge to edge control.
Basically they are lighter and stiffer than almost all touring boots out there, from the big touring boots to the race specific light boots.
It’s a small workshop in his basement where he and 5 other employees hand-mold and assemble the lightweight masterpieces.
Pierre raced for 12 years at the highest level and [besides other wins] he won the Pierra Menta stage race.
He also holds the ski record for Mont Blanc. With Stephan Brosse, he skied up and down Mont Blanc in 5 hours 15 minutes – the start and finish line was the church in downtown Chamonix!
Stano’s note: This is little more than 3800m of climbing, then skiing it down. Pierre and Stephan reached the summit in 4 hours. The record attempt also involved a small crevasse rescue.
After all Pierre’s racing at altitude and using his degree as a biomechanical engineer he started working to create the lightest and highest performing ski boot possible. Used in skis, sail boats and F1 technology, carbon fiber was the material of choice.
At the time it weighed 650g per boot and was nearly half the weight of the Scarpa F1 (1200g).
My 2008 XP 500 were down to 520 g per boot without liner in size 27.5.
This year, the new XP 444 shell weighs a cool 444 grams in 27.5 and comes with many other improvements as well.
The shape, especially around the ankle, is lower profile and more streamlined resulting in an even more precise fit, and less ankle bumping which can rip your race suit to shreds.
The distinctive yellow fiberglass tongue has been replaced with a lighter more sturdy carbon fiber tongue. Besides the weight savings, the upper cuff is 30% stiffer and the locking lever more ergonomic.
Poorly I might add, as the F1 Race locking lever is a real knuckle basher – Scarpa did fix that for the F1 Carbon.
Similarly, the new Dynafit and LaSportiva race boots have both developed one movement locking levers.
Pierre also makes a Mountain version with a protective rubber rand and a full Vibram sole – all that with just 56 extra grams.
The XP Mountain is a true lightweight touring boot. There is a rubber rand around the welt of the boot to protect the carbon fiber while scrambling around in the rocks.
And a full Vibram sole will give you the best grip and wear. All that for only an additional 56 grams still makes it an exceptionally light boot for extended tours.
One thing you may note of all these pictures is that there are not many boots in his workshop. That’s because they fly off the shelves.
Pierre and his crew produce about 300 pairs a year and currently there is a 6 month waiting list. So order now to get a pair for next season! They are well worth it.

Taking a long shot here that someone will read this super old thread, but here goes.
Basically I am looking to buy the old Gignoux classic liner as originally featured on the XP 444, this is the classic single piece liner and not the later bikini 2 piece model. Reason for this is to remove volume from my Alien 1.0, older model in yellow, not the current black. I have since I purchased these boots always used the liners from the original DyNA boots that were 7mm thick and took up enough volume for my skinny feet. Liners are now ready for the bin and as PG still sells these liners and they are 8mm thick I thought they might be worth a shot. I believe these were made by palau, liners which I have always found perform well. I also like the piece that sits atop the foot that looks like it will also take up volume nicely and provide comfort under the boa laces.
My question to anyone out there is how much ankle articulation did these liners give? I ask as they do not have the cutout section at the Achilles as all touring liners have today, but I am guessing from how I have seen people perform in these boots that they are quite flexible. If they are not so good my 2nd choice would be a 7mm model direct from palau. Thanks in advance from any info.

Hallo Michael
Hab seit einem Jahr den 444 Stiefel doch leider damals wurde eine falsche Umrechnung erstellt hab im Dynafit 27.5 mein 444 past jetzt leider in die Schalen Größe 29 von meinem Freund mir ist scho lang aufgefallen das ich keinen haltim Schuh habe ich hab das ganz neue Modell in südtirol beim Henry gesehen besteht die möglichkeit das modell schnell zu bekommen?Bin Sieger der Dynafit Tropfy 2010- 2. 2011-3.2012 Gsamt 19 Ötzi Alpin Marathon Vielen Dank für Deine Antwort im vorraus

Re: How robust PG boots are?
After some time of using them and seeing them (ab)used I am surprised how durable they are. Yes, occasional rivet needs a replacement but otherwise if you use them for touring without much rock mountaineering they do last.
I will post an article about this since Reiner Thoni skis them all the time with any skis since he got them. He even skied Mt Robson on Pierre Gignoux 😉
Michael Silitch says
Hi Michael,
How robust are the Pierre Gignoux boots? I would say surprisingly robust. Are they as robust as an all plastic boot–I don’t think so; The Pierre Gignoux’s are a formula 1 race car; They are what you want when you want the lightest, stiffest best performing boot out there.

Michael,
thanks much for posting this article- I’ve been combing through various skimo blogs, searching for input on carbon boots as a replacement for my F1s, a boot I use (in combination with my Trab Duo FreeRandos) for resort skiiing as well as touring. I’ve only raced once- after moving to Germany last year- but am willing to put out the cash for these after reviewing your comments here and on wildsnow.com regarding the improvement in skiability. I have but one question- how robust are they for full-time use? Thanks for your time,
Mike

Hey cool… the tongue looks just like the one I formulated for my F1’s. Nice pictures, especially the last one.

James, my foot measures 27cm, and Pierre sized me in the 27.5. I was nervous about, but it’s working out really well. I think my foot is about average, though, and not wide, although my toes feel cramped in many ski boots. I recall that you and I had similar sizing issues with the F1 carbon, so perhaps our widths are close. However, I think the PG 27.5 barely fits me, and your extra .5 cm, plus any extra width, suggests that you might want to take a look at the 28.5 if you can.
Also, I had to grind the opening of the shell wider so I could get my foot in, and to relieve pressure on the top of my foot. After that, and an extremely painful thermo fitting for maximum toe room, I find the boots to be quite comfortable, even for 6-7 hours.
Michael Silitch says
My foot is pretty much a middle width, but nina’s is kind of wide (24.5). Pierre wouldn’t let me take photos of his forms (the wooden things in the shape of a foot that the boots are built around)–apparently as with most outdoor shoe companies, those shapes are trade secrets. A good form can fit all sorts of foot shapes. I think his do, as I have never heard of people complaining about the fit.
Of note, especially if you felt the boot too tight once you got it, he has a new liner out, I forgot to mention in the article: The Bikini Liner. It is a two piece liner. Other companies, like dynafit have put a flexi fabric at the ankle hinge of their liner for better striding, but many athletes, including Florent Troillet cut out the section just above the ankle bone, entirely for freedom of movement in kick and glide and for weight savings. So Pierre Gignoux had a special “two piece” liner made. In talking to racers about it, the lower foot part of the liner is also quite a bit thinner, so if you have a wider foot, this would give you more room.
James says
Michael,
Would you say your foot is wide, narrow, in-between? My foot measures 27.5cm also but is pretty wide.
Michael Silitch says
Hi, someone asked about how to fit the PG boot when ordering. What Pierre’s site recommends is to measure the foot in centimeters and order that size. My foot was 27.5 cm long and nina’s 24.5 so we went with those sizes and they fit great.
