Tips for powder skiing

trav powder

You wake up on Tuesday morning and found 10 inches of fresh POW fell overnight. What do you do?

  1. Call in sick to work
  2. Break out the powder skis
  3. Rush to the mountain

Why a powder ski?

These skis are designed to keep the skiing on top of the snow. Depending on the type of powder ski, they can offer agility and maneuverability. They resemble water skis in shape, with a noticeably rockered nose to provide lift over the fresh snow. Their large width allows the ski to float over deep snow. They are usually fat, meaning having a waist of greater than 100mm and have reverse camber (the waist sits at the lowest point).

Now that you are at the mountain and geared up, make sure you understand the mountain terrain and understand the dangers associated with skiing on un-groomed terrain. Skiing powder has a different feel and does not behave the same as groomed trial, although the adrenaline rush of floating on the snow and the powder flying by makes it all worthwhile.

Here are some tips to ski powder.

  1. Maintain your balance. Keep equal pressure on both skis. Devin, a Green Ice Wax brand rep says “make a platform with your skis keeping weight distributed 50/50 over each ski” Keep the skis close together about shoulder width apart.
  2. Keep your hands up with your elbows in front of your torso. Do not lean back as you will lose balance.
  3. Keep your head up and do not pressure your edges as you normally would on groomed terrain. This will cause the one ski to dip further in the snow than the other.
  4. Maintain speed to keep from sinking and steer the skis into the fall line as you go down the mountain.
  5. Wax your skis. Powder tends to be more granular then groomed snow. The sharper the snow crystals, the more the need for wax. A sharp structure will cause more friction. Green Ice Wax makes safe and eco-friendly ski and snowboard wax which is long lasting and stands up to the rough shape of fresh “POW”.

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.

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.

Beveling the Edge of a Ski or Snowboard

Beveling the edge of a ski/snow board

When tuning a ski/board it is important to take care of the steel edges. The edges are filed and then polished with diamond stones of varying grit to remove burrs and harden the edge. To better understand why edges are beveled, it is important to understand what happens during the tuning process.

The diagram shows a cross section of an edge and each step of filing the base and side.

As you can see both the edge and base where filed resulting in a different shape. Since 3 °were taken off the edge and the base the result was still a 90 °angle.

Base and side angle increase performance of the ski/board differently.  If the 90 °edge/base angle was not modified it would be very difficult to ski/ride. The skier/rider would constantly “catch edge” and have minimal control.  Also steel does not glide as smoothly as the polyurethane base. Therefore, the base angle must be modified to reduce friction. The side angle is modified to grip the ice or snow on turns.

The typical angles used by manufacturers and shops are a 92° side angle and a 1° base. However, skiers/riders can change these angle based on the conditions of the mountain or the type of skiing/riding.
