INTUITION Sports out of Vancouver produces world class liners. These are premium liners that, when used right,
will do a whole lot for your skiing no matter what type of skiing you’re into. Not
only are they a godsend for performance, they are also a lot warmer than the
typical stock liners. I use them in the BC for touring and on the rare
occasions I ski in resort. My son Max, a U16 on the Park City
alpine ski team, uses Intuition’s HD Race liners in his Salomon Custom 130 race
boots. This year I am testing the brand new Pro-Tongue liners. But before getting into the liner review let’s take a quick look at boot and fit.
Step #1:
Make sure you have the right shells
Poorly
fitted boots is probably the main turn off for most beginners in our sport.
Having your feet in an ice cold and hard vice for endless hours does not
necessarily develop the kind of passion our sport deserves. So here are some
basics on getting yourself into a great fitting pair of ski boots. The main factors
determining fit and performance are:
- Size
- Shell and cuff shape
- Flex and your ability as a skier
The sizing proper is relatively straight
forward. There are basically three different sizing charts that you will
encounter when sizing (I do have a favorite but more on that in a bit): U.S. size –
Euro size – Mondo size. This last one is a disarmingly simple measurement based
on the metric system and measured in centimetres. For those that need a
refresher on metric, an inch is 2.54 centimeters and
an imperial foot (i.e. the measurement unit) is about 30 centimeters. Under
this system a Mondo size 25.0 is simply a 25 centimeters long boot
(i.e. about 10 inches)
measured from the heel to the toe inside the boot. Click here
for a good Mondo to “regular” conversion chart.
Once the
length is established, width is the next important measurement. This is the
width of your foot at its widest (the experts talk about “metatarsal” width).
As an example, if you are a US men’s size 10, then a foot width of about
3.8" is considered narrow, 4.0" is considered pretty standard and 4.2"
is considered wide (for all other sizes see table below). Knowing which width you
are will allow you to zoom in your choice on boots known to be narrow, medium
or wide.
Now to the
reason the Mondo is my favorite system: Whether you are buying/renting boots in
Alta, Chamonix or Rusutsu, as long as you
“speak mondo” you’ll be able to get what you need no matter where you are on
planet earth!
For shell and cuff sizes all boot manufacturers have a “standard”
foot and lower leg shape they model their boots on. The problem of course is
that feet come in all sizes and shapes. With each brand of ski boot having a
unique configuration of shape, volume, and geometry your challenge is to find
the manufacturer whose “standard” foot and lower leg shape matches yours the
closest. The only way to find out is to spend the time trying them out and
looking very carefully for pressure points. To figure out how a shell fit pull
the liner from the shell, insert your foot so the toes are just barely touching
the front of the shell, and measure the gap left behind your heel. A gap of
less than 1 centimeter
(a bit less than half an inch) is considered a snug race fit. A gap between 1 and
1.5 centimeters
would be a normal, high-performance fit for advanced to expert skiers. 1.5 to 2.0 centimeters
would be considered an ample fit for the skier that prioritizes comfort over
performance. At more than 2
centimeters of gap you probably need new shells. However,
and although not guaranteed, if you were to pick a high volume, high density
INTUITION liner you may be able to “save” such a shell. That’s how determining
these liners can be.
When trying
out boots in the store don’t loose sight of the fact that a subtle pressure on
your ankle in the shop can turn into major torture session after a few hours on
the slopes... Know also that if you find the 99% perfect fit but the boot fits
a bit too snug in a very specific area then heat “punching” the shell out to
fit is a very easy and fast step to take towards perfection. For the lower leg
shape a good thing to do if you find the boot is either too hard to buckle on the
cuff or too loose, is to unscrew the buckles on the cuff and move them one hole
or two either direction. This will typically just require an Allen key
(sometimes offered as a give-away with the boot) and can easily be done at home
and can make a huge difference in lower leg fit. Finally one word about half
sizes: They don’t really exist… The shell size doesn’t change and contrary to
popular belief neither does the thickness of the liner. Remember how we said
that Mondo sizes are one centimeter per size (a Mondo size 25.0 is 25 centimeters long)?
Well then a 25 and a ½ would be 25.5
cm i.e. a difference of 5 millimeters (1/5 of
an inch). The manufacturers feel that that difference is too small to justify
anything but a difference in the thickness of the insole. This is somewhat
understandable given the cost of a boot mould.
Finally, as
far as Flex and your ability as a skier are concerned know
that these two factors are closely linked. Typically the more advanced skier in
any given weight category will need or want the higher flex. However when it
comes to backcountry boots it seems there are precious little standards to
define the flex. So far I have always found that for the exact same flex
advertised on a resort or free ride boot I get a stiffer boot than its
corresponding ski mountaineering boot advertising the same flex. In general
true ski mountaineering boots, because of the requirement to keep the weight down,
are going to be less stiff than their beefier brethren in resort or sidecountry.
The liners
One key to
Intuition’s success is its use of a special formulation of the Intuition foam. Many
years ago that started in collaboration with Ultralon, a brand of EVA
(Ethylene Vinyl Acetate) thermoformable foam. Nowadays Intuition does it all on
its own and has developed the only foam formulation specifically fabricated for
winter sports (snowboarding and skiing). As a result, this foam is more
resistant to heat-related shrinkage and pressure related “packing out” than
other types of foam.
Intuition
liners are designed to improve on stock boot liners by:
Being lighter
and warmer
Being longer lasting
Offering a better fit and being tuneable
The
Intuition liner, once heated, will take the shape of your foot and your shell. Why does this matter
above and beyond comfort? Because with no empty spaces left between your foot
and the shells there is now a perfect transfer of energy from your foot to the
liner to the shell. This gives your ski set up an ultra-responsive feel,
because no energy is lost in open spaces or sloppy cushioning. I can say that
this is no exaggeration: The Intuition liner is really that good. Now, these
liners are no give-aways; at close to $200 I wouldn’t throw out my brand new
Garmont liners if the only thing the Intuition did for me was to offer some
vaguely improved comfort. For me the attraction is improvement in the performance (and efficiency) of light
backcountry boots that need all the help they can get in that area.
For a bit
over ten years now I have exclusively been using INTUITION liners in all my ski
boots. For resort skiing (rare) I use them in my Salomon X-Waves. In the back country
I use them in my old Garmont MegaRides 5my current “rock boots”) with Intuition
Pro-Tour liners and on my new Garmont (RIP) Cosmos with Intuition Pro-Tongue
liners.
INTUITION
PRO-TONGUE
The model
that Intuition designed for back country skiing is the Pro-Tour, not this new
Pro-Tongue. In my old MegaRide I used the Pro-Tour which is a great, pretty
high volume liner. That liner was so good it absolutely extended the life of
these boots. When I needed liners for these MegaRides I bought a size 28 Mondo
liner for my 28 Mondo size boots. The MegaRide size 28 has a sole length of 320 millimeters.

For
a reason that escapes me the size I need in the Cosmos is different so I ended
up with a boot size labelled 27.5 (just the 27) with a sole length of
306 millimeters. These
boots are lighter and narrower than my MegaRides but stiffer (advertising a
flex of 130). I clearly was going to need a lower volume liner for the Cosmos. I
picked the Pro-Tongue because they are thinner in the body and forefoot, with
an extra thick dense foam around the cuff and down the full length of the
tongue. The 2mm thick rubber ensures I am keeping overall volume in line
with the tighter boots (the Pro-Tour sole is 7mm). At the same time they
are dense and stiff enough in the cuff that I get really good support on the
downhill. I have been out on four outings so far and this liner is shaping up to
be the most responsive tongue liner I have owned. It reminds me of the high
performance feel I had a few years back in the Power Wrap (too voluminous for
these boots). So far I am very excited about the responsiveness and
performance I get out of these in cluding a week ago at
suicide chute. I was also just a couple of days ago out at Alta in 4° and the warmth and
comfort of these liners were irreproachable. I will do a more in depth analysis
of these after a full season with them but so far they feel like quite the
winners.

HD RACE LV
The liner my
son uses right now is the HD Race liner. This tongue liner is classified as a
low-volume liner. It is designed for low-volume and race-fit boots and that’s
what he is using them for. Interestingly enough he has been told his boots are
too large and he should go down a size. What he did was to get these liners
that are thicker than the stock liner and after heatmolding they filled up any
open spaces and he regained the level of responsiveness required of a race
boot. The feel as well as the training times he achieved so far in this
pre-season are very encouraging. I will get back with more towards the end of
the season.
