Known felted, wool, shoes, such as boots, contains a top, Stepovoy part and rubber sole, see the Internet information on the website Chechersky woollen factory, www.spec.techera.ru/valenki.htm

Known valjanye products has significant drawbacks:

heavy weight, heavy weight rubber soles that restricts movement when walking and creates discomfort in cold conditions,

sole made of thick rubber layer causes sweating of the feet and creates inside of the stop part unsanitary environment conducive to the development of different types of fungal infections on the feet,

the presence of a rigid, heavy soles, and sometimes threads firmware promotes rubbing the soles of the feet, the formation of corns, etc. injuries.

The closest technical solution is felted shoes for RF patent for useful model №122256 from 27.11.12 (prototype) containing the leg, Stepovoy part and the main sole is placed on the lower side of the stop part, and also includes a protective sole which is placed on the lower side of the main soles, made of EVA material, or from a compound EVA with rubber or EVA compound with PVC or EVA compound with polyethylene, she extra niteline contains removable insole, which made heated from ethylene vinyl acetate or other elastic material, and in the heel part of the insole is glued to the piezo from petrazzini.

The disadvantage of the prototype is the lack of elements of vibroprotection shoes.

Technically achievable - ensure the comfort of wearing shoes rescuer in the Far North is a seismic impact.

This is achieved by the fact that the shoes lifeguard to work at low temperatures with additional seismic effects, contains a top, Stepovoy part and the main sole is placed on the lower side of the stop part, with protective sole which is placed on the lower side of the main soles, made of EVA material, or from a compound EVA with rubber or EVA compound with PVC or EVA compound with polyethylene, it further comprises a removable insole, which made heated from ethylene vinyl acetate or other elastic material, and in the heel part of the insole is glued to the piezo from pietrini, for example, from polydimethylsiloxane thickness of 2.5÷5 mm, a size of 10×10 mm, while it is placed in a protective case, and a heating filament is connected to at least one piezoelectric element, located in the zone of the heel and/or toe, and a protective outsole milled footwear, located on the lower side of the main soles, made of double-layer with an intermediate layer of polyurethane and a layer of elastic mesh elements having shock absorbing properties and a running layer of thermoplastic polyurethane with a wear resistant properties, and the density of the mesh structure elastic mesh elements is in the optimal range of values of 1.2 g/cm3...2.0 g/cm3and the material elastic wire mesh elements - steel EI-708, and its diameter is optimum interval values 0,09 0,15 mm...mm

In Fig.1 presents the General design of the Shoe of Fig.2 - scheme of removable insoles for heating of the foot of Fig.3 - scheme of supplementary vibration protection insole anatomic form.

Shoes lifeguard to work at low temperatures with additional seismic impact contains the top 1, Stepovoy part 2, the main sole 3, placed on the lower side of the stop part 2, and a protective outsole 4 located on the lower side of the main soles 3 and supplementary insole 5 for heating the feet. The connection of the main sole 3 from the lower side of the stop part 2 is implemented by means of one or two twisted threads, have top - outside - down at an acute angle to the sole. Stitches the threads posted outside on the lower side of the stop part. In addition, the connection of the main soles 3 and sasanayodha 4 can be made by gluing, welding or other known method.

The performance of the main sole felted shoes from EVA fully achieve the stated technical result, as EVA - molded lightweight and elastic material with good shock absorbing properties, ease, abrasion resistance, odorless, non-allergenic, and with anti-fungal effect. Products from EVA have a high degree of softness and elasticity, are not subject to deformation, resist negative temperatures up to -30°, have a low degree of heat (thermos effect) and do not absorb moisture. EVA - this substance, which refers to the polyolefins obtained by copolymerization of ethylene and vinyl acetate monomer.

The acetoxy group is distributed in ethylene group arbitrarily. The vinyl acetate content determines the mechanical properties of the copolymer, as well as its type (elastomer or thermoplastic). Due to the high content of vinyl ethylene vinyl acetate acquires high resistance to oils, solvents, ozone and high temperature. It is also worth noting that the EVA copolymer has found wide application in the preparation of the compounds with other polymers, such as rubber, PVC or polyethylene, and mixtures with fillers and additives.

Supplementary insole 5 (Fig.2) placed in a protective Czecho is 6, the heating filament 7 is connected to at least one piezoelectric element 8 located in the zone of the heel and/or toe. In addition, the insole may be made of ethylene vinyl acetate or other elastic material, and in the heel part of the insole is glued to the piezo from polydimethylsiloxane (petrazzini) thickness of 2.5-5 mm, about the size of 10×10 mm in Addition, the case can be made removable. In addition, the case of the insole may be made of polycotton. The heated insoles through the case 6 through the heating filament 7 is connected to the piezoelectric element 8 in the periodic pressure which occurs with constant current. Preferably, the sensor was attached in the middle of the heel (model two piezoelectric elements in the heel area and in the anterior part of the foot, in this case, the heating power doubled). The use of piezoelectric elements as the heating element allows the use of insoles outdoors without risk to health, to maintain a comfortable temperature of shoes in the cold season. The maximum temperature of heating of about 45 degrees.

As the piezoelectric material can be used PZT (zirconatetitanate lead), transferred to a flexible sample PDMS (polydimethylsiloxane) thickness of 2.5-5 mm, (the so-called Pietras is on). This piezo deformation produces an EMF (electromotive force DC), sufficient to produce a current (not more than 12 mA) and voltage (36 In). It is possible to use other similar piezoelectric element and the piezoelectric layer. You can use any other soft and flexible piezoelectric material having EMF sufficient to produce a current (not more than 12 mA) and voltage (36 V) required for heating insoles. The temperature of the heating insoles depends on the characteristics of a piezoelectric material, the pressure force on the piezoelectric element, the length of the heating filament and other factors. The material of the cover insoles - polycotton, the cover is removable, allowing it to be washed when dirty.

A possible embodiment of the protective sole felted shoes, located on the lower side of the main soles and are made of double-layer with an intermediate layer of polyurethane and a layer of elastic mesh elements having shock absorbing properties and a running layer of thermoplastic polyurethane with a wear resistant properties, and the density of the mesh structure elastic mesh elements is in the optimal range of values of 1.2 g/cm3...2.0 g/cm3and the material elastic wire mesh elements - steel EI-708, and its diameter is optimum interval amount is 0,09 0,15 mm...mm (not shown).
