Snowshoeing :

Snowshoeing is the most affordable of winter activities. Low cost, it is also the one that requires the least physical skill and experience of winter or gliding sports.

 

 

Nordic skiing:

The world of Nordic skiing, that is to say all the disciplines where the heel is not always in contact with skiing, is very extensive. There are many possible combinations in the equipment that it is easy today to evolve in many different wooded or alpine environments, while experiencing very good skiing experiences. Nordic skiing is an activity that can be as physically as relaxing depending on how you practice it.

 

Range of disciplines include in ski touring (Nordic skiing)

 

Cross-country skiing (classic skiing, skating ...)

In cross-country skiing to move, the skier applies a push on the ski. In classic cross-country skiing, the skier follows traces dug in the snow by a ski center. The movement of the skier is a longitudinal thrust movement which combines a succession of gestures which together compose the technique of the alternating pitch.

In ski skate the push is lateral (as in roller blade). The skier uses a surface of about two meters groomed by the ski center. We usually find this groomed area is next to the tracks of classic skiing. The available skate skiing courses are nevertheless much shorter than the classic ski circuits.

 

In classic cross-country skiing, the ski grip on the snow that generates a forward movement is of two kinds.

· The first option is that of the sticky wax that is called hanging wax. The hanging wax is applied to an area of ​​the Nordic ski known as the waxing pouch. It corresponds to two lengths of boot sole. The sole of the foot is evaluated at 1/3 of the length of this zone and the remaining 1/3 being located in front of the foot.

· The second option is the option of scales or structures inlayed in the base of the ski in the same area as described above.

In cross-country skiing the phenomenon of gliding is favored by the installation of a gliding wax which is affixed to the skiing area of ​​the ski. This gliding zone is in constant contact with the ground and therefore the snow. This is not the case for the hooking zone which is in contact with the ground only when the skier is thrusting on the ski. It is also during the rebound of the ski that the energy is transferred on the opposite ski supplemented with a weight transfer that participates in the optimization of a sustained, redundant and cyclic movement. In ski skating the area of ​​gliding covers the entire surface of the ski. There is no hooking area.

Ski touring is akin to classic cross-country skiing. With the difference that ski touring is a discipline that makes it possible to move off-piste on any type of snow. Skiing less than a camber than a cross-country ski thus a response to less effective thrust. The alternative pitch movement remains the same but is less accentuated than in classic cross-country skiing.

At the level of ski grip on snow, most of the time it is a so-called mechanical grip that is the most used. That is to say with shell or structures inlaid.

As for skiing, it is the same process as for cross-country skiing. The touring skis are pre-stressed during manufacture, so they conform to an arched shape that allows an effective forward movement during a vertical thrust On the ski accompanied by a forward momentum of the skier himself.

 

Telemark

Unlike cross-country skiing and cross-country skiing which are two ways of skiing so-called cross-country skiing. Telemark is a discipline plus access on the descent. The ski has no such pronounced arch. The equipment used is more rigid, often heavier and more stable than that used in cross-country skiing.

In telemark, it is a system of skin of ascension also commonly called skins of seals that is most often used. These are rubber bands covered with synthetic bristles directed in the same longitudinal direction. This creates a directional brushing of the snow. This hair structure gives the skier a very good grip on the snow. This method of covering the ski base with an attachment layer makes it possible to raise the surface at high angulation, but it is not very safe and effective during the descent phases.

The skier must therefore take some time during his or her hike, mostly at the climax of the hike to remove and store his skins in his coat for the more adventurous or his backpack. Under no circumstances should during this transitional phase the skins touch the snow, it is likely to stick to the gluing adhesive on which the surface of contact between the skin and the ski is coated and to cancel the properties Adhesion of the skin.

 

Telemark Hybrid / Highway

The difference between these two types of skiing and skiing techniques lies not in the mode of attachment on the snow but in the type of binding used to make the link between the boot and the ski. In the so-called conventional telemark, 75mm fasteners are used more conventionally and in the telemark of performance the NTN standard is used. There is also a high performance French system that combines a NTN telemark position and a high road position with a heel TEC heel.

The hitch system most commonly used is the system of climbing skins.

 

High-road

It is a technique of skiing also very centered on the descent. It is the type of ski touring closest to downhill skiing since in downhill, the technique is the same. This is not the case of telemark since the telemark incorporates the concept of genuflexion which totally differentiates these two techniques. In high-road skiing, in English alpine touring, there are several fixing systems that exist. All these systems are extremely different from one another in terms of weight and efficiency in the transfer of energy and control of the boot to the ski.

There is also a category of high-road ski bindings adaptable to an alpine downhill ski binding.

The system that is experiencing the highest popularity is the latest time is the TEC system which is a system that is very light.

The hitch system most commonly used is the system of climbing skins.
