Montrail Helium GTX®
Test Series by
Background: I went on my first backpacking trip as a Boy Scout
at the age of 16. Over the years I have hiked the Wonderland Trail in
Washington and section hiked parts of the Florida Trail and the
Appalachian Trail. In 2003 during a seven week period I hiked 740 mi
(1191 km) of the Pacific Crest Trail. Best vacation I ever took. I
continue to backpack and hike year round in the Colorado mountains. I
have evolved from a heavyweight backpacker to a lightweight backpacker.
My three day summer solo adventures (using a hammock) have me hovering
around a 10 lb (4.5 kg) base weight. However while backpacking in the
winter I will be using a tent and additional clothing. So my base
weight will climb to approx. 17 lb (7.7 kg)

The boots arrived in a standard
These boots are big, sturdy, stiff and surprisingly lightweight. I am
so used to wearing low top running shoes for 90% of my outdoor
adventures that these boots are quite a change for me. I slipped them
on to see how the "straight out of the box" feel would be. They are
indeed big and stiff. These boots are going to take a bit of breaking
in to feel 100% comfortable. My previous big, heavy duty mountaineering
boots were made of thick leather and weighed easily twice as much and
took forever to break in.
Of all the boots and shoes on the Montrail website the Helium GTX
appears to be the biggest/tallest and most robust boot they offer. And
it only comes in a men's version. The boots do match the photos on the
site but the amount of
information supplied about the boot is a bit low for my taste. To be
fair these boots need to be tried on and seen in person. They offer
much more support than the photos would indicate. This is a tall boot
and measures 7.75" (20 cm) from the ground to the top edge of the
The Helium GTX boots are well made with no loose stitches and only the
smallest bits of extra glue being visible. One of the very top lacing
hooks on the collar was slightly flattened, so much so that I couldn't
slide the lace underneath it. I took a pair of pliers and opened it up
to match the others. Everything about these boots is robust. The metal
eyelets/hooks appear to be riveted (not sewn) to the upper fabric. The
toe cap and most fabric areas are sewn with two lines of stitching. The
toe cap and rand is made of a rubber like material, is quite thick and
wraps around the side of the boot a good 5" (13 cm).
The entire boot appears to be made of synthetic materials except the
top outside of the tongue and the top outside edge of the collar. These
areas are made of a medium gray suede leather.
The uppers are made of a heavy duty black nylon with additional
thicker, black and white threads criss-crossing, creating a very unique
pyramid pattern. The boots do have Gore-Tex fabric technology but there
is no indication if the Gore-Tex is laminated to the nylon fabric of if
there is a separate inner bootie. The website indicates that the
"Gore-Tex adds breathable, all-day
waterproof protection for crossing small streams and snow fields". I
be keeping a close eye on the breathability and waterproofness of these
The heel counter and toe area are very stiff. Using my thumb and
pressing down on the toe there is basically no give. Squeezing the heel
counter between my thumb and index finger also has no give. The upper
fabric area is stiff but has plenty of give. The tongue and collar
are well padded and soft.
The boot also has a stiff, molded one piece ankle support that runs
from the instep on the outside, wraps around high on the back of the
boot and finishes on the inside instep. This gives a tremendous amount
of lateral support to the ankle area.
The sole of the boot is thick and very stiff. The boot has a composite
shank that appears to run the length of the sole because the sole does
not bend at the toe area. The sole is pre-bent with a slight rocker to
it. This helps while walking but you still get that flat "Frankenstein"
feel while walking. However a stiff sole like this is great for use
with crampons and snowshoes.
The inside of the boot is lined with a gray woven wicking material and
the inside of the tongue is lined with an open hole mesh similar to the
mesh found on the inside of pack straps.
The insoles are a simple molded foam with a black fabric top. Pretty
I would consider myself to have pretty normal feet. They are of normal
width and my heel is not too thin. When I put these on for the first
time and walked around the house my toes had plenty of room and the
length was perfect. I wore two pair of socks consisting of a medium
thick merino wool sock with a thin wool liner sock (my normal sock
combination). When you slide your foot in you can really feel the heel
counter snug up nicely around your heel. The only area that gave me any
discomfort was ironically the tongue. The two inner edges of the tongue
pressed into the front part of my shins. I continued to wear the boots
for about an hour and even took the dog for a walk. The longer I wore
the boots the pressure did seem to ease up a bit. The next day I had
the same experience. Initially there was a lot of pressure on the front
of my shins but the longer I wore them and walked around the pressure
would ease up. This is the break-in period all stiff heavy duty boots
have. Some more than others. I will be keeping a close eye on how long
these boots take to finally settle in and mold to my feet. I will also
try thicker socks to see if this eases the transition.
These boots do indeed offer lots of support for heavy loads (which I
rarely carry) and for serious off-trail hiking (which I do frequently).
All that support at such a light weight is quite remarkable. The only
negative so far is break-in time (I'm spoiled with zero break-in for
running shoes) and the boots do not have a pull tab on the back of the
collar to help pull them on. So far this is not a big issue. They open
up wide enough and my foot slides right in.
expected these boots have taken some getting used to. For a boot this
robust the break-in time has been minimal. I estimate the first good 8
to 10 miles over numerous trips has finally gotten me to a point where
I can slip them on and go for a hike and not have any new pressure
points, hot spots or rubbing to contend with.
locations and conditions:
These boots have been used on almost a daily basis in and around
Boulder, Colorado. Between walking the dog, daily fitness walks and
weekend hikes in the mountains I estimate I have traveled a good 90
on these boots in the first 2 months of testing. They have held up well
and have far exceeded my
expectations. Temperatures have been between 60° and 0° F
-18° C) and elevations between 5000 and 9000 ft (1524 and 2743 m).
have been used on a multitude of surfaces including asphalt,
hard-packed dirt, muddy, rocky and rooted trails and on lots of snow
I have used these boots to climb Mt. Sanitas (twice), and on trails in
Rocky Mountain National
Park and the Indian Peaks Wilderness area (my normal stomping grounds).
The longest single day mileage has been 10 mi (16 km) carrying an 8 lb
(3.6 kg) day pack.
Sizing: I normally wear a size 11 and the length and volume of
this boot seems to be spot on for me. This includes my normal sock
combination of a midweight wool sock with a thin lightweight wool sock.
At one point I did replace the midweight with a thicker heavyweight
wool sock and the fit was only slightly more snug. I just loosened the
laces a bit and they fit fine.
Comfort: As I mentioned earlier there has been some breaking
in to do. The first day I wore the boots two areas of concern became
First: Where the tongue wraps around my ankle at the top created
pressure points on both sides on both boots. I switched to a thicker
sock and that helped a little. I went for a walk around the
neighborhood and when I got back the pressure seemed to have subsided.
At the beginning of every hike I would notice the pressure on the front
of my ankles. By the end of the hike it was pretty much gone. I believe
the tongue and ankle area have loosened up to a point now that the
pressure is gone.
Second: There are padded protrusions on either side of the ankle inside
the boot. They kind of sit in that indented area between your heel and
ankle bone. First time I wore the boots they were very noticeable. By
the end of the hike the pressure was tolerable but still noticeable.
Now you only notice them when you initially put the boot on. After a
couple of minutes of walking everything seems to settle in and become
With a mid-weight wool sock and a thin wool liner
my feet have been warm (while hiking briskly) down to 0° F
These boots are uninsulated but well padded internally which gives them
some insulation. When just standing around in the snow or during brief
rest periods my feet do
begin to chill in colder weather. This would not be my boot of choice
if I knew I would
be inactive in below freezing temperatures. The Gore-Tex® lining
also adds a small bit of warmth because it slows down evaporative
cooling. The lining is breathable but it keeps that warm moist air
around your foot longer than an unlined boot or a running shoe would. I
have also worn the boots when the temperature has been 60° F
(16° C) and the boots are a bit too warm for me causing excessive
sweating. I would consider this a cool/cold weather boot as long as you
keep moving if it is real cold.
Moisture management: The
Gore-Tex® linings classify these boots as "waterproof" and I would
have to agree. I have walked through snow, mud and on one occasion
while crossing an ice covered shallow stream my foot went through the
ice into 4 in (10 cm) of ice cold water. I pulled my foot out and the
rubber parts of the boot were shiny and wet. The nylon parts didn't
appear to be wet at all. I rubbed my hand across the nylon upper and
there didn't appear to be any water on the surface. So no water got in
the boot and no water appeared to soak into the nylon.
My feet sweat a lot on a normal basis. During the summer months I only
wear running shoes with lots of mesh and my feet still sweat a lot and
my socks collect moisture. The breathability of these boots is there,
but it is minimal. One of the things that I believe slows the
breathability is all the padding inside the boot. Most of the padding
is between .125 and .25 in (.3 and .6 cm) thick. It appears to be some
sort of open cell foam, but without cutting the lining to see I can't
be sure. At the end of a good hike my socks are wet. Not sopping wet
but definitely in need of changing.
Construction: Overall the boots
are very well made. They have held up well with only small scratches
and scuffs on the rubber parts. The rand is still glued tight and all
the stitching is
intact. The gusseted tongue has done a excellent job of
keeping debris out of the boot and the generous toe cap has protected
my toes from rocks and roots. The nylon areas are holding up extremely
well and still look brand new.
Soles: The soles of the Helium's have a proprietary
tread pattern and rubber compound referred to as Gryptonite™ “sticky
rubber”. The soles have lived up to their name with
good traction on most surfaces. The wear to the soles appears to be
minimal at this point.
Summary: After the initial breaking in period these
boots are beginning to be comfortable. They are lightweight but very
robust. They have excellent ankle support and give me a great sense of
stability. The only thing so far I don't like is the breathability. It
could be better but I think the trade off would be a less robust boot.
I have thoroughly
enjoyed testing these boots. Over the past two months my testing has
remained pretty much the same as my field report, consisting of day
hikes, walking the dog, shoveling snow and the occasional overnight
backpacking trip. Now that the weather is getting much warmer I have
been reaching for my trail runners instead of these boots. For
Colorado, especially the Front Range the winter has been mild with very
little snow. Until last week that is. We got about 14 in (36 cm)
dropped on us and the boots got a good work out to finish out this
locations and conditions:
Day Hike — Walker Ranch loop trail, 7.4 mi (11.9 km) in Boulder,
Colorado. The temperature started out at 40° (4° C) and quickly
climbed to 70° F
(21° C) with elevations between 6500 and 7500 ft (1981 and 2286 m).
The trail is extremely rocky in spots and there were patches of snow
and lots of mud. There were numerous mini streams from the melting snow
so the boots were quite filthy at the end of the hike.
Day Hike — Climbed Mt. Sanitas, 6863 ft (2091 m) in elevation with a
mile (5.1 km) hike to the top and back. This hike was very dry and very
warm. I got started late and the temperature was already 68° F
(20° C). There was no snow on the ground and the sun was blazing.
When I finished I really wished I had worn my trail runners because my
feet were very hot and sweaty.
Day Hike — Heil Valley Ranch loop trail, 8.1 mi (13 km) in Lyons, CO.
This was a much cooler hike. Started out at about 35° F (1.6°
C) and only got to about 50° F (10° C). Just about the perfect
spring hiking weather. The trail is pretty smooth with an elevation
gain from 5700 ft (1737 m) to 6800 ft (2072 m). The trail was dry,
sandy and a bit rocky in spots.
Overnighter — Finch Lake, west of Allens Park, CO 4.5m (7.2 km) one
way. Elevations run between 6400 ft (1950 m) to 9900 ft (3017 m). The
trail is very rocky in spots with very little snow but lots of mud and
wet areas. In several areas I had to wade through 3 in (8 cm) of ice
cold run off.
Performance: These boots
have done a magnificent job during the winter months. They can handle
moderate cold down to about 0° F (-18 C) if I keep moving. They are
not really insulated so just standing around in camp in those
temperatures led to chilly feet.
They can handle rocky, rough trails with ease. The soles are thick and
very stiff so even when scrambling over rocks or scree fields I never
noticed the rocks beneath my feet. The excellent ankle support gave me
a solid feel on the rocks. Not once did I feel like my ankle was going
to twist or that I needed to slow down and be overly cautious.
The soles have excellent traction and can handle mud, snow and slippery
The Gore-Tex liners are indeed waterproof. Not once, even when wading
through 3 in (8 cm) of ice cold water did they leak. If my feet had
gotten wet during that trip I would have been miserable the rest of the
trip. I probably would have turned around and headed back to the car.
These boots have excelled in the snow. I have traveled through snow up
to my knees and they have been warm, waterproof and with excellent
Now that they are fully broken in these boots feel wonderful on my
feet. It took a little while but it was worth it. No more hot spots and
no more blisters. Not bad for a boot that is this stiff and robust.
The boots continue to look really good. Other than some scuffs and
scrapes the boots are fully intact with no loose threads or separation
of the rubber parts. They are easy to clean with a quick spray under
water faucet and a light scrubbing with a nylon brush they are ready
for the next trail.
Summary: For me these boots are
going to be used more often when the weather is cool to cold. When the
temperature climbs above 50° F(10° C) they will probably be
home. Or if I know I will be traveling on extremely rocky trails and I
know I need the extra support I will bring them. But for summer hiking
on moderate trails they will stay at home. I love my trail runners and
they only get a rest when the weather turns cold.
I would like to thank BackpackGearTest.org and Montrail for the
opportunity to test these boots.
