Understanding Base Structure

A very important aspect of a ski/board base is its structure. Recall from , a board or ski does not slide on snow, it rides on water. As the base moves over the snow, the energy from the friction melts the snow. The base then rides over a small pool of water. The water then re-freezes after the base has passed. Therefore just as a car’s tires has threads, a ski or board should have structure to allow the water to flow unrestricted.

Most interesting, not all skis or boards have structure. Usually, a new ski has a structure out of the factory; however as people have their skis tuned, the structure may gradually fade if disregarded. In the back room of a ski shop, tuning machines have the ability to remove and apply structure. To remove structure, skis are driven over a sanding belt. To apply structure they are driven over a stone grinder, which has been cut with a diamond to apply a pattern to the ski.

When an economical tune is applied, a fine sanding belt maybe used as the last step, thus eliminating any structure. A racer or high performance tune is usually finalized with the stone grind, which imbeds a new structure to the ski /board. (See photo).

There are many technicians that believe that the structure is the most important part of the tuning and should not be overlooked. A good structure will not only provide speed but better control. Be sure that your tune up includes a base structure!

DemoDon’s XC Wax Review

demodon

As most skiers and racers understand, wax is most critical in Nordic skiing. Although speed is most important, it is necessary to be able to grip the snow when traveling up hill. While on the snow, cross country skiers will encounter various snow conditions. It is not uncommon to have soft snow in sunny areas and ice condition on the top of the course or trail.

Three advantages of using DemoDon’s Cross Country ski wax (made by Green Ice Wax) in the words of a Green Ice athlete are:

1. Skis run fast. Along with speed comes less effort to skiing.
2. They continue to run fast in the last half of the race or later in the day when other skiers had collected dirty skis with fluoro based wax. DemoDon’s wax stayed clean.
3. The kick wax, which is a tacky wax applied under the foot area of the ski, gripped well when stepping down and broke free to glide when speeding up again. This is critical as skiers do not want their wax to hold them back once they are back in the speed mode again.

DemoDon’s XC wax is available in a universal temperature, biodegradable glide and tack wax along with fluoro-free racer series designed for three different snow temperature conditions.

Three Reasons to Have Your Ski Boots Properly Fitted

Ski boots are notorious for being uncomfortable foot wear. Well they do not have to be if you chose the proper boot and have it fitted. Here are three reasons why a correct fitted boot is needed to ski properly.

1   Comfort. Boots must be comfortable if you plan on spending any time on the hill skiing. Just as any       footwear, ski boots come in different sizes. Typically your ski boots size not your shoe size. It is usually smaller. A good boot fitter measures your foot as to how it fits in the ski boot shell (see photo). With your toes touching the front of the boot shell (without the liner). The fitter determines how much room is between the heel of the shell and your heel. This length is determined based on the skier’s ability. A racer wants the tightest boot possible and will sacrifice some comfort. Just as good shoes come in width sizes (A through triple E), so do ski boots. Their width is called last. However, not every model ski boot come indifferent lasts. So you may not be able to get a specific brand and model if it does not come in your size.

Boot Shell, Liner, Footbed

2. Control. If a boot does not fit your foot snuggly and your foot slides either front to back or side to side, you will not have proper control over your ski. The movement in the boot is magnified by the length of the ski so when you put pressure to make a turn there is a loss of control as your foot slides before pressuring the ski. The best way to understand this is think that that your foot, boot, binding and ski all act as one unit.

3. Performance. High performance ski boots are quite stiff. Typically measured by the flex or pressure needed for the skier to lean forward on the front of the ankle.  Flex is determined by a relative number typically 80-150, the higher the number, the stiffer the boot.  The flex you need is dependent upon your strength, weight and ski ability. A racer uses a flex of 130- 150. Here again improper flex will affect performance. Too much flex will inhibit the ski from turning. Too little flex will not distribute the pressure properly again reducing performance.  

Flex

Once the best boot is chosen, there are many ways a boot fitter can make then comfortable without sacrificing control or performance. Boots can be modified by spreading, grinding and adjusting to remove pinch points. Boots should fit tightly but not hurt or cut off circulation in the foot. Many boot liners are moldable to the foot. They are heated prior to being placed in the shell or on the foot. They are allowed to cool which the foot is in the boot.

Recently, boot manufacturers came out with moldable ski boot shells. The shell is made of a plastic which is softened by heating. Once soft, the boot, including liner, is put on. A cold pack is placed around the boot followed by a pressurized pack. It is then allowed to harden in place and thus mold to the foot. The manufacturer of this technique calls it “Vacuum Fit” which is a bit confusing as the technique utilizes pressure (the opposite of vacuum).

Custom foot beds are a good choice. The foot beds are molded to the foot giving support to the arch and heel. Custom foot beds will help keep the foot in a neutral position giving the skier more control and comfort.

It is critical to choose a boot that fits snuggly without pain and whose stiffness matches the skier’s ability. Just remember a good boot fitter can adjust the fit of the boot as necessary to be comfortable, maintain control and achieve the best performance.

Green Ice Wax Endorses Nate Holland

Green Ice Wax introduces Nate Holland’s N8 wax. This wax is biodegradable and is available as a rub on and iron on wax. The eco-friendly aspect aligns closely with Nate Holland’s attitude towards preserving the envrionment. Nate Holland won 7 X Games gold medals in boarder cross, so he understands the importance of a high quality performance ski and board wax. The environmentally friendly wax is made from renewable resources such as plant waxes and oils. It helps reduce the carbon footprint by no longer using solvent, plastisizers or any petroleum by-products. These attributes eliminate the harmful effects on the user associated with applying iron-on waxing containing flurocarbons. More information on these harmful side effects can be found in our blog .

Wax Technology

It is always good to start with the basics. Skis or snow boards do not ride on snow! They ride on water. As a ski slides over snow, friction melts a thin layer of the snow, turning it into water over which your ski/board glides.  The water then re-freezes after the ski/board has passed, leaving a fresh track on the trail.

Ski/board’s bases are made of plastic (usually polyethylene) with a specially-designed structure.  This structure helps channel the water from the tip to the tail of the ski as you ski/ride down the hill. The idea here is to reduce the friction causing the ski to glide more easily and with less friction.  Less friction means more speed.

Wax is used to reduce this friction even further, and preserve the integrity and structure of the ski. Over the years, typical waxes have been made from paraffin wax (a product derived from petroleum).  As skiers became more conscious of the benefits of wax, wax formulators introduced additives into their products, such as fluorocarbons. These chemicals are excellent in reducing friction having a very low coefficient of friction. Overall, fluorocarbon waxes are great; however, they are dangerous to your health if you happen to breathe in the fumes during application. They hurt the environment, introducing fluorine into the snow.  As for high fluorinated waxes, most skiers will not even experience the full benefit of the wax because they are designed specifically for high-humidity snow conditions. Additionally, these waxes are very costly.

To combat these shortcomings of highly-fluorinated and potentially dangerous waxes, we borrowed a technology from the cosmetic industry.

This additive is not hazardous to your health and is more eco-friendly. Its coefficient of friction is very close to fluorocarbon, making it an excellent replacement additive. Both GI1K and 2K utilize this technology. The GI2K contains a highly advanced polymer which makes it more durable and longer lasting.

If you were wondering why waxes are made to perform at different temperature snow conditions, the reason is simple: The colder the snow, the harder the crystals. It is most beneficial to use a wax with a hardness matching that of the snow. Therefore, all Green Ice ski waxes have been formulated with differing levels of hardness.  If however, the snow conditions will be unknown, choose the middle temperature wax (18-28 degrees F) as this wax will suffice for most conditions a rider/skier experiences.

Green Ice 1K and 2K waxes have been proven to be very durable. They last longer than average fluorocarbon waxes and tend not to whiten the base of the board or ski. They perform well in all humidity conditions. Green ice 2K has excellent static and dynamic properties. There is minimal stick upon take off and your skis will glide over any terrain the mountain throws at you.

Finally our Green Ice Ultimate ski wax is 100% safe for the environment. We borrowed the plant waxes used in the automobile industry to create an environmentally friendly wax with plant bi-products as the only raw materials. Green Ice Ultimate uses absolutely no chemicals, solvents or plasticizers, only pure natural materials made from plants. Green ice Ultimate also incorporates a natural friction reducing additive, making it an excellent race wax or everyday recreational formula.

In summary:  Green Ice ski waxes are more durable and longer lasting. They work over a wide range of snow temperatures and in all humidity conditions.  They are also eco-friendly and do not require a respirator to make the application process safe.  Finally you will find them a cost effective wax solution for all skiing and riding levels.

Preparing for the Season

The leaves are changing, the air is cooling off, and girls are switching from shorts to yoga pants, but most importantly, snow is on its way. With the snow comes the most important time of the year, ski season. A lot of people who enjoy skiing or snowboarding will bring their gear to a shop to get ready in the beginning of the season. It’s similar in the spring when people bring their bike to the shop for their annual tune-up, or every 2000 miles when they change the oil in their car. However, unlike when the gears are skipping on your bike or the odometer has added 2000 miles, there isn’t exactly a super clear indicator of when skis need to be waxed. When your skis are inside, they are usually stored base to base, and when they’re on the snow, they are base side down. A quick look at the bases after a few days of skiing on them will reveal that they have changed color a little bit. A lot of skis have almost straight black bases, and the best indicator of when it’s time to wax is when they are getting a fuzzy white to them. Usually, this will start on the edges and work inwards. This is due to simply spending more time with weight on the edges, and can be thought of as how your tires might wear out on your car. Once this fuzziness starts to appear, it’s time to put some more wax on your skis to keep them happy.

A question that may arise if you take a look at your bases and they’re starting to look fuzzy might be “They don’t feel like they need wax, why do I need to wax them? I already had them waxed this year.” Well, the answer to that is because it’s a more gradual transition than the odometer hitting another 2000 or the gears on your bike starting to suddenly skip everywhere. In this case, the snow is like sand paper and the wax in your skis is the wood. One swipe of sand paper won’t make much of a difference, but after a few days of sanding, there will be a noticeable difference. The piece of wood will be smaller and smoother, and that translates to fuzzy looking and slower for skis.

Not everybody is a speed demon. If you enjoy skiing for the shear pleasure of spending time outdoors or with friends or family and have no need to go fast, then you might need a little bit extra energy at the end of the day to toast to a great day of skiing. Waxing your skis or board will give you that extra bit. Speed on skis is usually interpreted as how fast somebody is moving forwards. However, it also applies to sideway motion. While turning or stopping, there is sideways motion, and if your skis have no wax, then there will me more energy spent trying to get your skis or board to move sideways. Gravity pulls you down the hill, your legs move you from side to side on the hill. By keeping your skis or board waxed, you spend less energy. Less time spent telling your buddies that you’re “going to the bathroom” as an excuse for a break and more time spent actually skiing.

Another reason to wax your skis or board is the simple fact that it keeps your gear happy. If you run your car with nasty oil or ride your bike with skipping gears for a while without doing a simple maintenance routine, your car will break down on the free way or your bike chain will snap in the middle of nowhere. Skis won’t fail you should you decide to not wax them, but there won’t be nearly as much joy garnered from the use of unwaxed skis. Also, they will look much cleaner. The fuzziness will go away and small scratches will be very temporarily filled. Larger scratches should be repaired properly.

Waxing your skis or snowboard more often than once a year may seem expensive if you bring them to a shop every time or a hassle if you are more inclined to do it yourself. When going to a shop, don’t ask for a “tune up”, see if they offer a “wax only” or similar option. If doing it yourself is more appealing, try and find a friend to show you the basics. Either way, regularly waxed skis and snowboards are much more fun and easier to use than annually or never maintained gear.
