Crampons are considered a necessary element of tourist equipment for mountain tourism or mountain sports: mountaineering, ice climbing, ski mountaineering, drytooling and the like. Devices are a special metal structure that is attached to shoes and is used for reliable movement on firn (compacted snow), ice, or rocks. On the shoe sole is the base of the device, from which sharp teeth emanate, resembling cat paws with claws. The functionality of the entire device lies in these teeth, which, when passing through compacted snow, greatly simplify walking, properly distributing the weight of the human body. The pointed tips, which serve as a supporting element, simply cut the snow layer, which allows the athlete not to spend additional effort on trampling the path with the entire area of the shoe.To climb the ice cliffs, climbing crampons will become the most necessary item - their claws will cling to the ice surface, preventing the climber from falling down.

Modern models of the devices in question, as a rule, include two components in their design: the front part is fixed on the toe of the shoe, and the back part is fixed on the heel. Both of these parts are equipped with sharp iron teeth, which are the functional element of the cat. At the same time, the design also includes special fasteners for fixing the device on the boots.
IMPORTANT! Previously, people preferred to use models with a monolithic platform, however, it turned out that such options are inferior in efficiency to separate models, because. the latter distribute weight better.Thus, in our time, samples with a one-piece platform are very difficult to find on sale.
The design of cats can have a different number of teeth, which will affect their design:
In total, there are three ways to attach cats to shoes:
The auto fastener consists of a rear frog brace and a front retaining brace.This type of grip is the most comfortable in use, providing a real hard-hold adhesion that is only suitable for double-edged boots with braces.
On the other hand, the soft fastening is versatile, as their strap and elastic grips allow fastening on almost any type of shoe. It is worth mentioning that such a system is less rigid, because a person does not need to have certain skills in order to conveniently and tightly fix them.
Next: semi-automatic fasteners - they can combine the properties of both previous options, when the front tethered girth is connected to the rear fixing "frog". Accordingly, it is possible to fix such variants of crampons on boots with double welts, this is especially true for special (but not ordinary !!!) climbing shoes.
As a standard of modern style (for the segment of mountain shoes in the “hi-fashion” category), it is possible to cite three options for fastening on the example of products from Grivel (hereinafter, the markings are indicated):
Today, crampon sets on the market are immediately equipped with some options for fasteners and fastenings, in order to ensure that the user has the opportunity to adapt them to the existing arsenal of "athlete/tourist" mountain shoes. A striking example here is the devices from the Petzel company with the LLF Universal technology, which allows changing the form of its fixation from semi-automatic to automatic, and vice versa.
In any case, the method of fixing crampons should be selected in direct proportion to the model of footwear that is supposed to be used.And this will depend on the features of the terrain to be overcome. In overwhelming cases, many models of cats have systems for convenient adjustment to shoe size. Nevertheless, you need to make sure on the spot, at the time of purchase, that this or that model of crampons really fits the chosen type of mountain boot. This factor is especially relevant if it is supposed to use non-standard options, when the boot size is either very small or very large.
Climbing crampons, which are used by tourists and athletes of our time, can be divided into four main types:
In the old days, the availability of high-quality mountain equipment was available only to mountain shooters from various power units. Such injustice gave rise to the mass production of handicraft models of cats, which were not very reliable. However, some craftsmen "from blacksmithing" were quite capable of forging massive cats (usually from steel).The essence of the handicraft technology was that the claws were made separately, and then, using special screws, they were fixed on ordinary climbing shoes. If you dig deeper into the history of this fact, then, according to the bushes, it was preferable to fix cats on hockey skates. This method justified itself by the fact that the sole of a hockey skate is extremely resistant to manual modifications. The oldest and most popular method of producing artisanal cats “at home” is the method of attaching an iron plate with small teeth, which is fixed to the front of a hockey boot. The entire structure is held by steel rings, along which a dense tarpaulin belt is passed, which makes it possible to strengthen the fixation.
Today, the risk of creating and using homemade products is absolutely not justified. And the question is not even that the technological process will take a lot of time and require a lot of effort from the master, which will simply be due to a decrease in the degree of safety of using such a device. This can be explained as follows: any screw that is screwed in the wrong order (outside of factory production) will definitely have an effect when the user climbs sheer ice. Moreover, a poorly made device is quite capable of simply flying off the leg, damaging the boot, and even injuring the lower limb.
Important! It is always worth remembering that mountain equipment is not the elements of an extreme hike that you can save on. User safety is paramount!
In principle, there are not so many tips for putting equipment on boots, but they should be followed.This is especially true if the user is going to visit difficult areas:
The main principle of selecting cats is their adaptability to the development of the future route to be conquered. It should be remembered that aggressive cat paws with pointed teeth, coupled with a rigid mount, are only suitable for difficult routes, which abound on surfaces with ice.
Lightweight models, with a reduced number of teeth, are intended for movement on firn or fragile ice.
As a rule, cats are made of EXACTLY rusting alloys. Thus, storage should take place in proper condition, exposure to moisture should be prevented and they should be "listened" to squeaks when used. It is always worth checking the crampons for correct fastening: they should not hang out. If such situations take place, then it is necessary to fasten the bolts (for older versions) and damaged rivets in a timely manner. At the same time, it is necessary to monitor the condition of the buckle straps.Any damage to these elements, even the smallest, must be excluded.
Undoubtedly, the usual sharpened teeth are effective enough for thin ice, which allows the user to move on it without problems. Nevertheless, they can also do harm if their use and transportation "leave much to be desired." From this it is clear that if the cats are not “on their feet”, then it is preferable to carry them in one way: to equip them in a special bag made of durable fabric, which is simply impossible to make a hole, after putting rubber tips on the claws (which are very difficult to find in size). ).
As well as any object that should have sharpened edges, this device (cat) wears out and becomes dull. Sharpening of fangs for cats should be done before each season, sometimes even more often if it involves long trips. To a greater extent, this applies to both ice and rock climbing. To sharpen claws, you can use both a simple file and machine equipment. The main thing is that the following requirements must be met:
A variant of simple anti-podlips for cats that are not characterized by anything special. They are able to establish, more or less, reliable adhesion to the surface (necessarily together with crampons), on which the athlete / tourist ascends. Nevertheless, they have proven themselves not badly, judging by the reviews of the indigenous inhabitants of the permafrost regions (USA, Russia, Canada). Perfectly able to prevent the appearance of frost on cats. The recommended cost for retail chains is 1000 rubles.
A good representative of the budget class, which has a large number of teeth. Judging by the reviews, it is quite suitable for overcoming horizontal icy surfaces. Its spikes, although they seem impressive, are definitely not suitable for conquering Everest. It's all about the weak alloy used, which, although hard, can collapse at the slightest sharp mechanical shock, which for this device is an overload. The recommended cost for retail chains is 1300 rubles.
These cats are an excellent item that can prevent falls from an icy slope and at high altitude.The model is available in 4 sizes, which allows you to adapt them to any shoes. The teeth are sharpened in a special way, which means confident grip on reliable surface points, additionally supporting body weight. These cats will be useful both for hunting participants and for trekking and mountain running. The recommended cost for retail chains is 3200 rubles.
The design of this device has 12 teeth, which is a classic option. Mounts are made of soft plastic. At the same time, the kit includes anti-slip pads and a bag for transportation. In the manufacture of this model, all past "negatives" were taken into account, which did not pass the certification of CE, EN and UIAA standards, as well as the ISO 9001:2008 quality system. At present, all processes are regulated at the level of the competent EU authorities. The recommended cost for retail chains is 4300 rubles.
This model is optimal for winter trekking (which implies the possible training of military special forces). The design assumes a six-prong base with adjustable shoe size. At the same time, the adjustable fit of the boot is carried out with the help of ratchet locks, which are not designed for NATO boot standards.From this it is clear that the cat can only be fixed individually, by adjusting its base to the appropriate boot. The recommended cost for retail chains is 6,000 rubles.
This sample is a completely updated version with universal mounts. They are durable and stand several positions higher in terms of availability in terms of quality. Their new properties lie in the hybrid connection of steel with flexible plastic plates, which together makes movement on ice as stable as possible. Boots fit almost any, from simple to special mountain or trekking. Fastening is carried out by nylon straps, which have proven their reliability. The recommended cost for retail chains is 10,500 rubles.
These crampons represent a new class due to their updated flexible platform. Despite their sufficient mass, they are able to fully satisfy all the needs of both an industrial climber and an amateur climber. Fastening to shoes is carried out with reliable nylon straps, which are equipped with stable clamps. The recommended cost for retail chains is 8500 rubles.
This option, in principle, is ideal for people involved in industrial mountaineering. There are 12 claws in the model, 2 of them are forged (which means their durability). It is possible to switch to a monotooth. The three internal tines help keep the body weight at the right height and provide the maximum load on the foot for traction when holding on to the slope. The remaining teeth maintain the desired immobility of the body position at a height. The kit includes: anti-slip pads and a carrying case. It is worth noting that the "claws" have anti-corrosion treatment.
In this model, the front teeth act as length adjusters, moreover, they were given a couple of holes, since the toe itself became little needed. In this model, the geometry of the teeth has changed dramatically and their average pair has increased in length. The kit comes with Bouncer Fakir III anti-slips - they are made of soft metal, which is adapted to work effectively at low temperatures. The recommended cost for retail chains is 15,000 rubles.
Climbing crampons are the best option for extreme enthusiasts (as well as athletes) who want to protect themselves on “unstable” routes. In addition, everyone will be able to choose the most suitable model for themselves, which will serve "faithfully" for many years, of course, subject to proper operation and care for it.
