What is crucial to achieve a reliable kick? Part III.: correctly defined kick area of the ski

In the article "What is crucial to achieve a reliable kick? Part I.: right stiffness and length of the skis” it was explained that skis base for classic cross-country skiing style consists of three parts / areas, two gliding areas (one in tip and one in tail of the ski) and one kicking area (in the centre of the ski).

If the skier is standing on both skis, in other words skier’s load is transferred to both skis equally, the middle area (kicking area) should not touch the snow surface and the skis should glide on the snow surface in the tip and tail areas (gliding areas).

In the opposite if the skier concetrates his/her load on one of both skis, the middle area is pressed down and get in touch with snow surface enabling the kick.

For a reliable kick is thus responsible stiffness and length of the skis (they must correspond with the weight and height of the skier) but also the length and position of the kicking area.

If the kicking area - where kick waxes are applied - is A. wrongly positioned along the ski or B. too short or too long no reliable kick can be provided.

If the kicking zone is correctly positioned, but too short the consequence is missing kick but still good gliding properties.

If the kicking zone is correctly positioned, but too long the cosequence is A. a reliable kick but bad gliding properties or B. freezing wax with no kick and horrible gliding properties or C. skis do not enable any movement.

If the kicking zone is incorectly positioned, the result is normaly too long kicking zone with consequences A / B / C depending on other factors as snow conditions, wax type etc.

Conclusions

Define the kicking area where kick waxes are applied carefully before you start to ski. If you do not know the kicking area, apply the kick waxes in a short window which can be increased with insufficient kick. In direction to ski tail the kicking zone ends latest where the ski boots end. If you need to improve kick properties by enlarging the kicking zone, go direction to tail first and stop at ski boot end. After you have reached the ski boots end, enlarge the kicking zone in direction to tip.

For whom is mohair the right choice?

Background of Mohair - alternative for kick waxes

Kick waxes are used for classic cross-country skiing style enabling forward movement on skis in the ski track. Unlike the skate style, the classic cross-country skiing style requires the use of an agent enabling the “kick”. To enable the “kick” and thus the forward movement in the classic cross-country skiing style kick waxes - as hard waxes or liquid waxes - were used for many years.

Problems with kick waxes

Kick waxes - especially the liquid ones - are hard to be applied on the ski base. There are plenty of kick waxes for different snow types and temperatures ranges. Use of kick waxes was connected with many troubles = they did not enable the “kick”, they froze and rubbed off while sliding...

Skate style

All these problems of kick waxes accelerated the development of the skate style where no kick waxes need to be used. We could also say that popularity of the skate style originates in the problems of kick waxes.

Problems of skate style

Skate style can afford advanced skiers only and skiers in a good physical condition. If you are skiing uphill in skate style, you have no support of the kicks, you need to skate and glide up to the top of the hill which can be very challenging especially for untrained skiers.

Other alternatives for kick waxes

Especially the high requirements for physical condition and skills in the skate style re-started the search for other alternatives for kick waxes as it was clear and obvious that skate style is not the right option for ski tourists. Beginner skiers and especially ski tourists need for their cross-country skiing trips the kick to move slowly and comfortably in the country. They are ready to give up some of the gliding qualities - if skiing downhill - for a reliable and easy kick - if skiing uphill.

Mohair as a modern alternative for kick waxes

Mohair seems to be the right solution for these tasks. It worsens the gliding qualities of the skies acceptably and in the most of snow conditions it provides a more or less reliable and easy kick enabling an easy and comfortable forward movement on skis uphill.

Mohair limits and problems

Especially in cold and icy conditions and in very wet spring snow conditions mohair cannot provide a reliable kick because there is nothing to catch the hair on. In cold and abrasive snow conditions mohair can be worn quite fast. In moist snow conditions close to zero mohair can have the tendency to freze and needs to be protected by anti-freze agents.

Despite the limits and possible problems mohair seems to be a very good alternative for kick waxes especially for ski tourists and beginner skiers.
