Historical
Development: Snowshoeing is known to have been
practiced in present-day central
Asia about 6,000 years ago. It is
believed that as these ancestors to
the Inuits and Native Americans,
migrated from Asia to North America,
they brought the snowshoes with
them, which were modified slabs of
wood. It was not too long before
this evolved into the white ash
framed snowshoes with the raw hide
lacing that we associate with
snowshoeing today.
Until the 1970’s, snowshoes were
used primarily for employment and
survival rather than recreation, and
the primary materials utilized in
the construction were wood (white
ash) and rawhide. The wooden
snowshoes are generally categorized
in three different styles or
shapes. The oval shaped bear paw
was designed for use in forested
conditions where maneuverability was
most important. The truly long (46+
inches) Yukon snowshoe was developed
for traversing deep powder-covered
open areas, common in the
Northwest. The beavertail seemed to
take advantage of the best features
of both the bear paw and the Yukon,
and has been utilized in all types
of snow conditions.
Neoprene
Decking:
During the 1960’s, snowshoe
manufacturers began to offer
neoprene lacing as a man-made option
to the rawhide laced deck. Modern
recreational users and professionals
appreciated how neoprene did not
stretch like rawhide when it became
wet, and did not require annual
treatment with shellac.
Difficulties
with Woodies:
Those introduced to wood framed
snowshoes often-encountered
difficulty with the bindings and
keeping the snowshoes on. Users
also experienced a lack of traction
on ascents and lateral traverses on
wood-framed snowshoes, unless they
took the time to fabricate their own
traction devices and adhered them
directly onto their decking. Those
who used wooden framed snowshoes
also found that the straddle walk
required by the wide snowshoes
brought on the feeling of tired hips
after a few miles of steady
walking. These difficulties were
all overcome with the modern
snowshoes.
Aluminum Framed
Snowshoes:
Gene and Bill Prater developed the
oval-shaped aluminum framed Sherpa
snowshoe and steel hinge rod in 1972
in Ellensburg, WA to overcome some
of the deficiencies they encountered
with wooden snowshoes while doing
winter mountaineering in the
Cascades. The Sherpas steadily
replaced wooden snowshoes among
professional users, including
foresters, rangers, trappers,
guides, mountaineers, and the
military. Sherpa’s neoprene decking
was replaced with polypropylene in
1989, making the snowshoes much
lighter.
Redfeather
Leads the Way: Redfeather
introduced the aluminum framed
beaver tail snowshoe with hypolon
decking in 1990. A hypolon toe cord
was utilized rather than the
Sherpa-patented steel hinge rod, as
Sherpa retained these patent rights
for another two years. Ironically,
the Redfeather Snowshoe Company
probably spawned the original boom
in snowshoe racing, as Tom Sobol of
Leadville, Colorado as well as
several other running enthusiasts
captured onto the sport, and held
several well-advertised events in
the state of Colorado. The
light-weight design of the
Redfeather Snowshoe, with its red
anodized aluminum 8” X 25” frame,
retained the traditional symmetrical
tailed design of the Michigans that
have existed for centuries. The
excitement of racing being done by
those who were summer participants
in triathlons and marathons brought
credibility and attention to the
sport of snowshoeing, and started
the wave of snowshoeing that
continues today. Redfeather
Snowshoes promoted Tom Kettlehut as
President and CEO in January 2002,
from General Manager and Director of
Operations. Redfeather experienced
growth of 21% in 2000-01, and he
hopes to continue with 15-20% growth
over the next three years. (Outdoor
Retailer, Jan, ’02)
Tubbs Snowshoe Company, owned by Ed
Kiniry in Stowe, VT introduced the
Katahdin and Sierra in 1991 after
extensive research and development
work coordinated by Rick Howell. An
interesting side note for Alpine
skiers and cyclists: Rick Howell
invented the step-in ski bindings
while attending high school, and
then invented the step-in cycling
pedal system after waiting at a stop
light and observing a cyclist who in
his attempt to release his feet from
the pedal straps, crashed onto the
highway beside Rick’s car.
Sales Growth:
Snowshoeing’s boom followed the
growth of running, cycling,
triathlons, and Nordic skiing in the
1980’s, and the development of
modern aluminum framed snowshoes
enabled users to enjoy snowshoeing
from their first step. The
marketing strategy employed by
Tubbs’ General Manager, Kathy
Murphy, along with Kiniry’s
financial backing, enabled Tubbs to
ride the wave, as snowshoe sales
have increased at more than 20% per
year through the 1990’s. According
to the National Sporting Equipment
Association, US outdoor enthusiasts
purchased 444,000 snowshoes in 1994,
while 640,000 were purchased in
1995. For the first time ever,
over a million pairs were purchased
in 1996. More than 5 million Americans
went snowshoeing in 2000 – 3 % of
all Americans over the age of 15 –
according to the Outdoor Industry of
America. There appears to be no
slump for the sport, which has
mushroomed over a decade with annual
increases of 20 – 30%. (Outdoor
Retailer, January 2002)
Over thirty manufacturers
currently market aluminum-framed
snowshoes, led primarily by Tubbs,
Atlas (owned by Tubbs), Redfeather,
Sherpa, and TSL. TSL, based in
France claims about a third of the
Global market, maintaining a solid
hold on European sales. (Outdoor
Retailer, Jan. ’02)
Heel Mounted
Traction Devices, Plastic Decks &
Elastic Bindings:
Since 1994, snowshoe manufacturers
have included a second traction
device under the heel, to complement
the traction device under the ball
of the foot, near the toe cord or
hinge rod. This heel mounted
cramp-on or traction device has
again aided on lateral traverses,
ice covered ridges, as well as
ascents and descents. Snowshoe
consultants designed their own heel
cramp-on, which was adopted by Tubbs
for the Kathadin and Sierra models.
Within a single season, both Tubbs
and Sherpa made the heel cramp-on
available for those who already own
their snowshoes. The dual cramp-ons
are now a standard feature on most
models sold.
Mountain Safety Research (MSR)
introduced a well-received one-piece
plastic decked snowshoe in 1995-96,
which was followed by several other
manufacturers in 1996-97, including
Tubbs and Redfeather. The elastic
material used in the MSR and
Northern Lites binding is
manufactured by Voile, and enables
users the ability to quickly put on
and take off the snowshoes. Another
MSR development is the tail
extenders, which can quickly and
easily be installed or removed for
quick storage. The most recent
innovation is the heal elevator,
that was developed by Bill Forest,
who developed the snowshoes for
MSR.
The small, but enthusiast racing
community drove many of the
developments. The primary concerns
of the athletes - light weight,
durability, traction, positive
response and price are usually the
same requirements of the
recreational, backcountry and
professional user as well. Each
user group places varying degrees of
importance to each of these
concerns, depending on their own
personal needs.
Step-In
Bindings:
One of the most recent innovations
include the step in binding,
designed by Bill Prater of
Ellensburg, Washington with
collaborative efforts from Andy
Davis, a ’97 Forest Recreation
graduate of Paul Smith’s College.
The step - in binding enables users
with crampon compatible boots to
easily step from the snowshoes to
their crampons and then back to
snowshoes. This innovation was made
available to the retailers in
1997-98.
For the 2002-03 consumer, TSL
will have an integrated boot and
binding with Lowa. Lowa, working
with Vibram (of Italy), collaborated
to design this snap-in feature in
their AT boot line. The uppers are
a combination of leather and W.L.
Gore’s winter Gore Tex, with
Thinsulite underfoot and a PU
midsole. The outsole has a bar the
passes under the ball of the foot
from one side to the other, like an
axle. The ends of the bar snap into
place on the pre-mounted snowshoe
binding. The step-ins will be
available on the TSL’s 205 and 217
models, both priced under $200. TSL
is well known in Europe for its
aluminum-frame and one-piece
injection-molded snowshoes, and Lowa
began importing the TSLs this
season. (Outdoor Retailer,
Jan. ’02)
Sizes:
Most aluminum snowshoes are either
8” X 25” or 9 X 30,” while several
other sizes are also available.
Consistent users have found that
these sizes, although typically
smaller than traditionally thought
necessary, will best meet the
floatation needs under most
conditions. It is possible that in
the dry powder conditions found
along Lake Superior in Minnesota,
the Northern Rockies, the Wasatch
Range of Utah, the Northern
Cascades, as well as the Sierras
along the California/Nevada border
may require larger snowshoes than
the conditions usually found in the
east. Each region has its own
distinct snow density and moisture
content, which both play an
important role in floatation.
Women’s Market: Unlike much of the
Outdoor specialty market that is
dominated by men, the snowshoe sales
have indicated that 50% are being
purchased by and for women. Tubbs’
research indicates that half of all
snowshoers are women, up from 40% in
the late 1990’s. Tubbs, which
currently has six models for women,
has seen sales quadruple in three
short years. (Outdoor Retailer,
Jan. ’02)
Additional
Equipment:
Telescopic poles, although certainly
not necessary, will aid the user
while ascending hills, walking the
flats and while pulling gear in a
mountaineering sled. Telescopic
poles enable the user to adjust the
poles’ height to snow depth and the
terrain. Additionally, the poles
can easily be adhered to the
backpack when not in use.
Safety Concerns
Heat Loss:
There are five ways in which the
human body can lose heat in the
winter. (1) Radiation is the
movement of heat from a warm
environment (the body) to a colder
one (the air); (2) Convection is the
loss of heat to air moving across
our surface (wind); (3) Conduction
is the loss of heat to a colder
object in contact with us (sitting
in the snow); (4) Respiration cools
us, as we are breathing out warm air
and inhaling cold air with every
breath; and (5) Evaporation burns
energy (calories) and heat by
converting moisture on our skin to
gas or water vapor.
The primary heat loss concerns for
most snowshoers should be protection
from the wind (convection), and
evaporative heat loss. Snowshoers
by the aerobic nature of the
activity are generating enough heat
so that usually radiation is not a
major concern. It is a concern
while getting the snowshoes on, as
the body’s caloric expenditure is
still quite low. Snowshoers must be
aware of the potential risks of
conductive heat loss at times such
as when putting on the snowshoes.
Touching the cold aluminum frames
with bare fingers can be a rude
experience. It is best to have a
thin layer of gloves on to protect
your fingers from conductive heat
loss that occurs quickly when
touching frigid metal objects.
Clothing:
Snowshoe footwear begins with a thin
synthetic sock and then a synthetic
and wool blend sock. A racer or
endurance athlete will wear a
lightweight synthetic sock and
standard training shoes for
snowshoeing. Some boot
manufacturers have begun to market
specialty snowshoe footwear. These
are not necessary, and are probably
a fine example of America’s
marketing excellence.
For most weather conditions,
snowshoers will be most comfortable
with fewer clothes than most
observers would expect. A layer of
synthetic polypropylene or bi-polar
underwear (tops & bottoms) will
protect the snowshoer from
evaporative heat loss, while a wind
barrier layer will protect from
convective heat loss (wind). Both
layers will be all that is required
for most half-day (up to six hour)
snowshoe outings. An additional
isolative layer such as fleece
should be stored in your backpack
for the stops along the trail.
Otherwise, the caloric expenditure
of snowshoeing is usually more than
sufficient to maintain body
temperature.
Hydration: It is important to
constantly be aware of the need to
stay hydrated, especially during the
dry winter months. Even indoors,
the consistent dry air will steal
moisture from areas of high moisture
content, including the human body,
your pet, and your wooden
furniture. You can see this in
wobbly chairs, interior doors that
open and close readily, your dog’s
water bowl that constantly needs
filling, and in the touch of your
own skin. Native people recognized
this, and developed skin
moisturizers from indigenous animal
and plant sources to maintain moist
skin during the dry winter months.
We need to do the same, and also
drink plenty of water throughout the
day. It is easy to see some of your
moisture escaping you during
exhalation, as a cloud forms with
each breath. This looks impressive
near bovines and other quadrupeds,
but they too need to constantly
re-hydrate as well. The need to
stay hydrated cannot be
over-stressed during the winter
months.
Many of us do not drink enough water
year around, but we have silly
reasons for being dehydrated during
the winter. We do not want to stop
and pee in the cold conditions of
the outdoors, a situation that is
likely to come about anyhow, as our
urinary bladder constricts due to
the colder outside temperatures.
Some of us feel that the cold
temperatures of many beverages will
(and unfortunately they do) reduce
your body temperature. You should
then drink warm beverages if this
could potentially become a problem
resulting in hypothermia. Where
to Go: The beauty of snowshoeing is
that you do not need a trail or pay
a user fee to enjoy an hour or a
day. Any area with public access
that is covered with snow is a
viable snowshoe adventure.
Snowshoers are able to traverse
areas that would be all but
impossible to traverse during other
seasons, as the snow depth and
frozen water provide the floatation
necessary for the snowshoes.
The development of snowshoe trails
has been a recent phenomenon, as
Nordic ski centers and nature
centers have been taking advantage
of snowshoeing’s dramatic growth
while Nordic skiing has been in a
steady decline over the past five
years. It is certainly easier to
snowshoe on packed trails, but users
should spend some time off trail to
truly take advantage of the
floatation and maneuverability of
the snowshoes.
Stationary and moving water should
be avoided until the ice depth is at
least 4” deep. Sudden immersion
into ice-cold water should be
avoided.
Impact on the Environment: The
depth of the snow will protect the
vegetation from damage and impact
from the snowshoes. Once above tree
line, it is still of utmost
importance to stay on the designated
trail, as the fragile alpine
vegetation is even more vulnerable
to damage caused by human impact.
The traction devices can
mare-exposed rock above tree line,
in the same way as crampons.
Snowshoeing actually provides a
welcome relief to non-hibernating
animals, as the snowshoe trails will
harden up overnight, making it
easier for animals to traverse a
region the following day. The slow
speed of snowshoers does not seem to
startle wildlife in the same way as
cross country skiing and
snowmobiling. |
