description
The Lowa Vertex GTX boots (hereafter called the Vertex or the boots) are
a medium duty hiking boot, with an interesting difference when compared to all
of the other boots I have owned.
The boots came in the box pictured above. Inside of the box was a
pamphlet containing care and use suggestions. The left boot also had three hang
tags attached. One was from GORE-TEX. The others are from Merrell discussing
the Biomex Protection System, and another of general consumer care tips.
The Vertex is a full height boot, as opposed to a low or mid. They stand 7.5 in (19 cm) high at the
front/tongue. The outside is made of what the company only calls “Synthetic, microfiber material combined with tough, abrasion-resistant
nylon”, and limited areas of leather.
The ankle cuff is nicely padded. The tongue is bellows-style to help
keep debris out of the boots. It has a lace-loop centered near the top to keep
the tongue from sliding sideways during use.

The most interesting part of the Vertex (and the recipient of many awards) is
the Biomex system. This is the light gray plastic wrapping around the boot that
is seen in these pictures. It attaches to the boot at the black plastic disk on
the sides. Here is what Lowa says about this system.
” BIOMEX® is a unique
technology that combines an innovative ankle support system in lightweight
construction. Originally developed to protect snowboarders and in-line skaters,
BIOMEX® is now available for hikers exclusively in LOWA Boots.”
“Virtually every hiker has experienced an ankle twist or sprain at some
point. That's because traditional boot design, which is based on a straight,
vertical axis, has little to do with our bodies' actual geometry. As a result,
the foot tires after a short time and becomes more prone to tripping. Once a
trip or a twist begins, the leverage from the front of the foot creates
pressure on the lower ankle joint, and presto, a sprain just ruined someone's
day.”
“BIOMEX® is a simple yet revolutionary approach to protecting the ankle. It's
based on the premise that prevention – in this case, ankle stabilization –
equals protection. By stabilizing the ankle with a flexible, articulated cuff
that's positioned at an offset angle, rather than on a straight vertical axis,
the ankle is no longer subjected to the twisting forces that cause injury.”
There is a hefty rubber rand protecting the toe of the boot, along with a
section of the sole that wraps up on to the front.
The round nylon laces run through a loop of leather above the toe and
then thread through a series of 8 metal loops as seen on right. There are two
pairs of speed hooks at the top.
The Vibram Vertex soles, seen below, have the
usual aggressive treads, (what they call “non-slip universal profile”) and the famous yellow Vibram elongated octagon logo of course. They are attached
to the boot with some type of adhesive. The soles have a dual density
construction (the light gray seen above the lugs is stiffer) and continue up at
the heel quite a ways for added stability.

Inside of the boots are some thin insoles that are nothing to write home
about. I did not replace them on my first pair, but am going to on the next.
The quality of the Vertex boots seem to be very good.
The stitching is all straight and uniform. There were no loose threads or
blemishes.
Field Conditions
I have worn the Vertex boots on four major trips. They have been used in Yosemite National Park,
the Sierra National Forest, the John Muir and
Minaret’s Wilderness areas.
They have been worn in San Jacinto Wilderness and the Bristlecone Pine
Forest in California, along with Buffalo State park
in Minnesota.
The elevations have ranged from lows of 100’ to over 13,200’ (30 to 4,023 m). I
have had them in rain and snow as well as nice dry trails. The lowest
temperature encountered with the Lowas strapped on
was a chilly 17 F (-8 C) morning in the Sierra Nevada.
The highest was in Minnesota
where it was about 85 F (29 C). I have worn them on dirt, mud, pine duff, rock,
scree and snow.

Observations
I bought these boots in September of 2005. I had a 100 mile (161 k) trip
planned for October on the John Muir Trail. I had liked what I had read about
the Vertex boots in the magazines and thought that the extra ankle support
might be a good thing. I took them to Minnesota and walked a
couple of days at a nearby State Park while my children were in school. I
probably put less than 10 miles on them to “break them in”. They were very
comfortable right out of the box.
I took a lot of extra moleskin along on the JMT trip as the Vertexes
were still pretty much new boots, and I was worried about blisters. I needn’t
have. I have never got a blister while wearing these boots.
The strange looking hinged exo-skeleton around
the top of the boots actually work as advertised. They have proven to be very
stable. I had some concern that it would be stiff bending forward with the
hinge point, but that did not prove to be the case either.
It was because of this level of ankle security that I chose them to wear on my
climb of the Cactus to Clouds trail, what Backpacker Magazine listed as the 5th
toughest day hike in America.
Most of it is on a very rocky unmaintained trail that
rises through the desert in Palm Springs to the
top of Mount San Jacinto. In 11 hours, I went 23
miles (37 km), with 10,700’ (3161 m) of gain. Again the boots performed
excellent.
I always wear a liner sock and medium to full weight wool sock with these
boots. (The weight depends on the temps expected on the hike.)
The GORE-TEX liner worked very well also. I love to just blast through
water if it is not too deep. And blast I did on the JMT and up at San Jacinto. No water got through to my feet.
I took the Vertex boots on a 33 mile (53 km) trip to White
Mountain in May 2006. As we had a very long approach hike and
would be on a varied terrain (rock, dirt, snow and ice) I figured the Lowas would be able to do it all. I brought some Grivel AirTech2 crampons to use with them and some MSR
Denali EVO Accent snowshoes. Once again they had excellent support, traction
and comfort.
But the GORE-TEX liner failed on the first day of the trip, in the toe
areas on both boots. The front of my feet were soaked, which is not good when
you are camped in the snow at 11,200’ (3414 m) and it is going to drop to 28 F
(-2 C) in the night.
They are showing a lot of wear for the amount of mileage put on them so
far also. They have only 166 admittedly tough miles (267 km) on them to this
point. I feel at the price point these boots occupy, they should get a lot more
use than what I have seen.
Because I had been so satisfied with the boots performance in 2005, I
bought another pair in March of this year. I did not expect to have to break
them out of the closet so soon though. I have two hikes coming up this year
that will put 140 miles on the new pair. I will track the results of their use
and put an addendum to this review next winter. Hopefully the early failure of
the first pair will prove to be an isolated event.
Pros: Excellent support, great
traction, comfortable.
Cons: Seemingly poor durability,
weak GORE-TEX liner.

Customer Service Addendum July
2006
In July I took the Lowa boots back to REI and told them about the failure of
the GORETEX and the amount of mileage and use incurred. They sent the boots to
Lowa and said they would contact me with the results.
I was informed that the GORETEX could not be fixed (which I expected) and that
they would have to replace the entire boots. (That too I expected.) But the
company decided that due to the amount of wear that they would have to pro-rate
it and would send me new ones for $50.00 (US). (This I did not expect!)
They asked me if that was OK. As I try to find the humor in everything I
laughed and said that I guess it is going to have to be. They asked if I agreed
that it had excessive wear to which I replied yes they do, but the fact that it
got that excessive wear in only 166 miles (267 km) and over the course of 8
months, which last I checked was under a year, I don’t understand them not
being covered completely. I gave them my credit card info and expect to see
some new boots soon. I will very carefully track the usage of the new boots
again.
I honestly do like the boots a whole lot. (I am going to start breaking the new
pair in this weekend for two upcoming hikes.) But this has soured it a bit for
me.
