The advantages of these ski mounts include a relatively low price. Usually they are preferred by amateur skiers and tourists.
SNS - ski bindings created by Salomon. This development is based on the use of guides and flexors (springs, rubber bands). have one longitudinal guide to stabilize the sole of the boot. Ski bindings are available in two types: SNS Pilot (designed for skating) and SNS Profil (universal).
NNN - developed by Rottefella later than SNS. It is distinguished by the presence of two parallel guides for fixing the sole. It has three types of ski bindings - for the classic style of skiing, "skating" and universal.

Both systems (SNS and NNN) allow excellent control of the skis. It should be noted that both SNS and NNN are very high class devices. Athletes - representatives of the world's biathlon and skiing elite - use these types of bindings.

How to choose cross country ski boots

When choosing boots for cross-country skiing, you need to decide how often and what style you intend to run. If you plan to go skiing only a few times a season, is it worth spending serious money on equipment? And vice versa, if you plan to ski quite often or do sports at all, then you need to approach the choice of boots more seriously.

In either case, you can pick up decent and high-quality boots and bindings. In general, the price when choosing boots and bindings plays far from the main role. The most important thing is that the chosen sports shoes are comfortable to run. But you should think about bindings only after you have already chosen shoes. This is because they are made for a specific type of mount.

Many companies produce models of shoes specially designed for men and women, as well as children's models. This diversity is dictated by the difference in the anatomical structure. Men's feet are much wider than women's. In addition, women's and children's shoes are made more elegant.

Since the choice of ski boots and ski bindings are interconnected, it is worth learning a little about ski bindings.

What are the bindings for skis

For felt boots, ski bindings are soft, made of leather straps. For other shoes, bindings can be semi-rigid or rigid. These have been fasteners for a very long time. And today they are no longer used for cross-country skiing. Nobody skis in felt boots today.

Today everyone skis in ski boots. But shoes are also different. After all, they are made for certain fastenings. What types are in use today?

Types of ski bindings

There are four types of ski bindings in use today:

NN 75

Let's take a closer look at each type of attachment.

NN 75 or Nordic Norm 75, where the numbers indicate the width of the mount. This is an underutilized type of mount. It is a metal case in the form of a horseshoe with three rods - protrusions. For him, a boot with a slightly protruding sole is used. It is installed on the fastening rods, the protruding part of the sole, in which there are respectively three holes.

Then the front, protruding part of the sole is clamped with a metal bracket and latched with a special latch. A boot with such a mount does not hold tight enough on the ski and may hang out a little. It is not suitable for skating at all. But after all, some twenty years ago, it was on such bindings and boots that everyone rode.

But progress does not stand still. And a Norwegian company Rottefella improved her creation, and without further ado called it NNN, adding one more letter to the old name.

NNN or New Nordic Norm. The mount is made in the form of a plate that is attached to the ski. It has two longitudinal guides that fix the boot from lateral movement. On the sole of the boot there are two longitudinal recesses for guide fastenings. A transverse rod is mounted in the front part of the sole of the boot, with which it snaps onto the mount.

Thus, the boot is fixed in the longitudinal direction. And so that it does not hang on this rod, its front part rests against a special elastic band - an emphasis. By selecting the stiffness of this gum, you can control the stiffness of the entire mount. Rottefella fasteners are used by such well-known companies as Rossignol, Fischer, Alpina, karhu.

NlS or Nordic lntegrated System appeared in 2005 in the same company Rottefella. The mount is placed on the skis without the use of screws. However, skis must be specially prepared for this. They must have the NIS platform installed. The rest of the mounts are almost the same as the previous version.

This type of binding is used by sports equipment giants such as Rossignol, Alpina and Madshus. Accordingly, the price of such mounts is higher.

SNS or Salomon Nordic System - cross-country ski bindings developed, as the name implies, by the French company Salomon. The boot is fixed on the ski using one longitudinal guide. Ahead of the boot is fixed with a rubber stop.

The company produces 2 models of mounts: Pilot and Profile. Mounts of the first type are specialized and are intended only for use in skating. Because of this, they have two guides, and instead of rubber stops, spring ones are used. And the Profil model is universal and traditional for the company. Salomon bindings are used by Adidas, Atomic, Spine, and Salomon itself.

Which bindings for cross-country skis are better

It is impossible to say unequivocally which bindings for skis are better. But let's try to understand this issue.

The outdated NN 75 mount, although used less and less, is much cheaper than other types. And, despite its shortcomings, it still finds fans. In addition, it is often bought for children. Its price is relatively small, and a growing child will have to change shoes in a year or two.

The NIS mount is mainly used by professionals and enthusiastic athletes. This is primarily due to its price. And the benefits are not so obvious. Therefore, the most common mounts are NNN and SNS.

Ski mount NNN and SNS and their difference from each other

Both types of mounts are similar in shape to each other. There are also few fundamental differences. The main difference is that the SNS type uses one longitudinal guide while the NNN type has two longitudinal guides. For a skier, they are approximately equivalent. Both those and others are used by both professional and amateur athletes.

How to choose ski boots by size

In order for the shoes to sit comfortably on the foot, they must be correctly sized. To do this, they need to be measured. You need to measure them, wearing the socks with which they are supposed to be worn.

If the skier already has some experience, then good. If not, then when choosing socks it is better to play it safe a little. Or do you want your feet to freeze? And if not, then you can purchase thermal socks specifically for this case. And grandmother's woolen socks are also suitable. In extreme cases, you can wear several pairs of socks.

After the shoes are dressed, they are laced up. If possible, you need to walk a little back and forth. If shoes are chosen for the classics, then try to stand on your toes, as if doing a push with your foot. If shoes are selected for a skate, then place your foot with an inclination, simulating a skate course. If everything is fine and the leg is comfortable, then you can buy.

How to choose ski boots for your running style

The choice of boots and bindings also depends on whether it is supposed to be skated or classic. Different styles They also have different requirements for boots and bindings. So, for example, for skating, boots are made taller and stiffer. For the classics, shorter and softer. All major manufacturers Sports Equipment, offer boots for both skate and classic.

How to choose ski boots for skating

For skating, boots are made higher. This is done in order to fix ankle joint. The skating style of running assumes that during the push the leg is placed with an inclination, and the ski is on edge. And in order not to twist the joint and reduce the load on it, it is fixed with a high boot.

Here, a thicker sole is used. The shoe itself sits more tightly on the foot. It is made taking into account the anatomical structure of the leg. For skating, you can use boots with bindings of both types: SNS and NNN. In addition, there are combined shoes. This is something between a classic and a skate. And for fixing the ankle they use a removable cuff.

How to choose ski boots for classic skiing

Ski boots for classic move, whether it is a product from Fischer, Salomon, Alpina or another company, is slightly shorter than for skating. There is no need to fix the ankle joint. But, nevertheless, boots for the classics are made by leading companies, taking into account many requirements for skating boots.

A classic boot is a little lighter than a skate boot. They use a softer sole. Mounts are used by both SNS and NNN. Only if the preference will be given to the SNS type, a small nuance should be taken into account. Boots with Profil bindings do not fit on Pilot bindings. On the contrary, it is quite suitable. But don't forget that the Pilot is designed for skating only.

How much do ski boots and bindings cost

Modern ski boots from well-known companies are made from high-quality synthetic materials and from high-quality genuine leather, fluff. Therefore, they are very light and warm. Accordingly, they are significantly more expensive than products of less well-known companies.

The price range is very large. This is understandable. They start from one thousand for simpler boots, up to several tens of thousands for a product for professionals. Good ones can be purchased for two to four thousand rubles. Good mounts also start from a thousand rubles and end in many thousands.

Skis today are produced for a wide variety of purposes - for beginners and experienced athletes, for running or mountains.

Accordingly, the models differ in the materials from which they are made, in length and width, and necessarily in the types of fasteners.

Since the choice of ski shoes depends on the selected bindings, and sometimes even special design solutions are required in the arrangement of the skis themselves, the issue with them should be addressed first.

Retro style mounts

Considered obsolete, but mounts known as NN-75. These are the devices that the parents of today's athletes used to call tough.

They consist of a plate with pins and a clamping bracket. Boots for such bindings must have appropriate holes in the sole.

Such mounts are very cheap, but are gradually being replaced by other designs.

It is claimed that they do not allow the use of skating (although non-professional Soviet skiers somehow managed to do this). But the fact is that this system leaves the heel unfixed.

Modern Fashion - SNS and NNN

The most common types of cross-country ski bindings today are called SNS and NNN. Each of them requires a special type of shoe, there is no compatibility between them (although it is possible within the same group of bindings).

Both of these systems are distinguished by the presence of peculiar guides instead of pins (in the first case - one, in the second - two), which securely fix the foot with the help of similar grooves in the sole of the boots.

Both types of fastening are distinguished by rigidity. It is determined by the indicators of the rubber bands against which the boot rests during the push. They can be distinguished by color or applied numerical marking. Mounts SNS for skating they are sometimes released with special springs instead of rubber bands.

System NNN however, it differs closer to the foot (almost under the fingers) by the location of the fixing spring, which also facilitates the movement of the “skate”.

In both of these types there are varieties that fasten automatically and require manual work. Experienced athletes usually choose SNS with manual fastening (they are more reliable), and beginners - NNN with automation (they are cheaper). These types of bindings are suitable for any shoe size.

Technical novelty NIS

Another type of ski binding for cross-country skis appeared in 2005. Its designation is NIS. The difference here is not in the principle of fixing the boot, but in the approach to the idea of installing the ski bindings themselves.

They can be fastened without screws, very quickly, and also moved along the ski. There is only one problem - only skis are suitable for this, on which the appropriate platform has already been installed in the factory.

In this case, special shoes are not needed - boots with a standard sole will do.

If the athlete intends to take only the first steps on skis, he the first is better purchase equipment in accordance with the recommendations of a professional consultant.

And there is no need to strive to immediately buy all the most expensive - such equipment is intended for professionals, and completely different models and designs are suitable for beginners.

Fastening videos

To get real pleasure from skiing, you should pay attention not only to the choice of skis, but also to the quality of the bindings. Bindings are a kind of drive, an important link between the legs, shod in boots, and the actual skis. If not everything, then a lot depends on the quality of this “intermediary”. What is the best ski carrier?

Selection of ski bindings

The right mount tightly covers the shoes, but at the same time it is able to quickly come unfastened in a critical situation. For example, if you suddenly fall during a sharp turn.

Another important point! Under heavy loads, the binding should respond adequately - continue to hold the foot in place, and not immediately unfasten.

Choosing the right mount starts with... selection. Having shoes suitable in size and all other characteristics in your sports equipment, you can start choosing bindings for specific shoes and available ones.

General information about skis and bindings

Skiing is an ancient invention. They first appeared about 4.5 thousand years ago in Scandinavia. And to this day, many improvements have been made.

For fasteners, this transformation is the most impressive. The banal tying of the leg with a belt passed through four holes sawn into the ski has been replaced by modern fastening systems made of plastic and metal.

Due to the wide range of ski equipment on the market and the literal translation of most foreign names into Russian, choosing a fastener for a beginner is not an easy task. The concept of "cross-country skiing" is especially broad. They can be "professional", "racing", "recreational", "universal" and so on.

It is best to choose inventory, based on speed.

Sports equipment will be required for those who ride at a speed of 15 to 30 km / h on a good track.
Amateur equipment is ideal for those reaching speeds of 9-15 km / h.
Movement on the ski track no faster than 4-8 km / h will require tourist equipment.

Types of ski mounts

Mounting is carried out directly on skis or on special platforms. The latter can be installed by the manufacturer and have pre-drilled holes. In this case, the fasteners themselves will have to be bought by a certain company. Any fixing systems can be placed on platforms without holes. Holes in this case are drilled independently.

Mount consists made of two separate parts and a plate under the toe, which reduces the friction of the boot. The front part is responsible for the side release, the back provides the upward release.

The size of the front and rear coverage is the same for all models. So you can use shoes any manufacturer.

Mount adjustment skiing carried out depending on the weight of the skier. It also takes into account the experience and manner of skating. When skiing aggressively, the skis should not come loose.

To determine the unit of actuation of the fasteners, you need to divide the weight of a person by 10. And for beginners, subtract 1-2 units from the resulting indicator.
The maximum adjustment limits for ski bindings are plus or minus 3-4 units from the figure obtained at the beginning (weight minus 10).
Sometimes the force is indicated not in units, but in kilograms. In this case, 20-30 kilograms are subtracted from the weight.
To install the correct fastening unit, you can use the special tables that come with the fastening system. It is better for inexperienced skiers to resort to the help of an instructor or a seller.

Mounts are:

Fastened by hand. Disadvantage: relatively high price.
Semi-automatic and automatic. disadvantages :
- jamming when water enters and freezes;
- may not open without support on a hard surface (for example, when falling into deep snow).

Fastening features for cross-country skis are determined by the tracks on which they are used. When driving on flat or slightly rugged terrain, simplicity and low weight of the mounts are required.

Manufacturers produce 3 main types ski bindings: Roteffella ( NNN system and its new version NIS), Salomon (SNS system) and c (familiar to everyone in the USSR).

1 77 mm (NN 75)- consists of three spikes mounted on a metal plate with a springy shackle.
