The deep-treaded MONO-PU sole with a 9 mm profile is a mono-density profile sole. It is antistatic and provides good slip resistance, even when moving sideways. This sole profile is particularly suitable for the outdoors, such as in forests and woodlands and on rough terrain. The outsole is heat resistant to approx. 180°C and flexible at cold temperatures to approx. -20°C as well as oil and fuel resistant.

The deep-treaded PU/PU SAFETY-GRIP 2 sole is a double-density sole with a 6 mm profile. It is antistatic and provides good slip resistance. The soft PU core in the midsole provides good impact absorption and high wearing comfort. The outsole is made of PU and is particularly abrasion-resistant, heat-resistant to approx. 130°C and flexible at cold temperatures to approx. -20°C as well as oil and fuel resistant. The sole is based on the SAFETY-GRIP sole concept.

The deep-treaded RUBBER SAFETY-GRIP 2 sole is a mono-density sole made from rubber with a 6 mm profile. It is antistatic and provides good slip resistance. The outsole is abrasion resistant, nick-resistant, heat-resistant to approx. 200°C, short-term even to approx ca. 300°C, and flexible at cold temperatures to approx. -20°C. The outsole is also oil and fuel resistant and resistant to many chemicals.

The deep-treaded RUBBER sole is a mono-density sole with a 6 mm profile. It is antistatic and provides good slip resistance. The outsole is abrasion resistant, nick-resistant, heat-resistant to approx. 200°C, short-term even to approx ca. 300°C, and flexible at cold temperatures to approx. -20°C. The sole is also oil and fuel resistant and resistant to many chemicals.

The soft PU core in the midsole provides good impact absorption and high wearing comfort. The outsole is made from rubber and is particularly abrasion-resistant, nick-resistant, heat-resistant to approx. 200°C, short-term even to approx ca. 300°C, and flexible at cold temperatures to approx. -20°C. The outsole is also oil and fuel resistant and resistant to many chemicals (acids and lyes). The sole is based on the SAFETY-GRIP sole concept.

The individual pieces of the upper, from the various materials, are cut out/punched out using cutting dies.

The difference between the two insoles is the contact resistance. An ESD shoe has a specified contact resistance of 10⁵–10⁷ ohm.

The inlay soles are distinguished by comfort and function. b-dynamic or ERGO-ACTIVE inlay soles support the foot and provide the foot with more safety in the shoe.

Distinctions are made between 4 different methods of production. Soles can be cemented, the so-called AGO method of production. In this method, the upper and insole are cemented together, the outsole is then cemented to the upper.
Another method of production is the injection moulding/vulcanisation of the soles to the upper. In this method, the insole is cemented to the upper or joined (i.e. fastening the upper with a zigzag seam). The upper is then placed in a mould in which the sole is directly injected. By this method, the heated sole material (e.g. rubber or polyurethane) is fed into the mould where it then has to cool off. The upper edge and the sole bond during cooling. The profile of the sole is determined by the mould.
Soles can however also be sewn. A distinction is made between the "stitched method" and the "welt sewn method" with sewn soles. In the stitched method, the outsole is sewn on through the insole and through the upper edge after the last has been removed, while in the welt sewn method an edge is cemented under the insole and in a subsequent step sewn to the upper by means of a leather strip. The outsole is then sewn to this edge. The last method of production for wood-nailed shoes is rarely used today. In this method, the outsole is fastened to the insole using wooden pins.

Leather is not a uniform product. Even with similar leathers, there are differences in appearance, quality and in the leather's characteristics. This is due of course to the fact that leather is a natural product.

Double-density profile soles comprise a midsole and an outsole. In this case, the midsole is usually somewhat softer and responsible for cushioning, while the outsole comes into direct contact with the ground/floor and is responsible for slip resistance as well as for heat, oil or chemical resistance.

The symbol E indicates that the heel fulfils the additional "energy absorption capacity" requirement.

EDL (ELTEN DISTANCE LINING) is a distance yarn made from microfibres. The capillary action provides a better moisture transport. EDL is certified in accordance with the Öko-Tex (Oeko-Tex) Standard 100

Protects the foot on different kinds of grounds and stabilises the step.

The ELTEN Basic inlay sole is made from fleece which provides a good moisture absorption and release. The material is particularly sturdy. The inlay sole is also replaceable and antistatic.

Asymmetric steel toe cap for optimal toe-room and an extra wide fit to accommodate the larger foot.

Especially high degree of flexibility and wearing comfort.

European and international standard that specifies the requirements to be fulfilled by safety shoes intended to protect against chainsaw cuts (forest)

European and international standard that specifies requirements to be fulfilled by safety shoes, so that the wearer is protected against injuries that can be caused by accidents. Shoes that are tested according to this norm are equipped with toe caps designed to protect against impacts with a tested force of at least 200 J. Furthermore, they have to withstand pressure loading of at least 15 kN.

As opposed to the French stitch, English sizes are measured in inches. A size here corresponds to 1/3 of an inch.

Elten Ergo-Active sets new standards for wearing comfort. An innovative fitting system has been developed together with the Eberhard-Karls University in Tübingen (Tuebingen) that makes it possible to provide the right shoe for every type of foot. The foot is measured exactly with highly sensitive cameras. An exact data image of the human foot with a personally precise shape is available in seconds. This means a twofold advantage for the wearer: Objective assistance in the selection of the right shoe and significant time savings. Time-wasting fitting is no longer necessary. Wearing comfort and enjoyment are improved. Both make a real contribution to foot health. The ERGO-ACTIVE foot type system provides 3 fit options, the right shoe for everyone.

• Foot type 1: for large feet, short toes, wide ball and heel widths, steep ball angle
• Foot type 2: for feet of average width, long toes, average ball and heel widths, flat ball angle
• Foot type 3: for narrow feet, with average toe lengths, narrow ball and heel widths, ball angle between steep and flat

The ERGO-ACTIVE ESD inlay sole is part of the ERGO-ACTIVE system. It is available for every foot type and in the weight-optimised comfort classes soft, medium and strong. The ergonomic chassis also provides improved stability of the heel.

ESD shoes (electrostatic discharge) do not primarily protect the person but rather protect the electrostatic discharge sensitive devices in sensitive working areas. With a contact resistance of 10⁵–10⁷ ohm, electrostatic charging is reduced by diverting the electrostatic charge.

• ESD-DESIGN: The ELTEN ESD inlay sole is conductive and fulfils the DIN EN ISO 20345 and DIN EN 61340-4-3 standards for electrostatic discharge areas: protection against electrostatic discharge (electrostatic discharge = ESD, contact resistance 10⁵-10⁷ ohm).
• OPTIMAL FOOT CLIMATE: High moisture absorption and release because of the PU foam's open cell structure. This keeps the foot comfortably dry.
• SHOCK-ABSORBING AND COMFORTABLE: The extreme softness of the PU foam absorbs shocks on impact and increases walking comfort.
• ODOUR-NEUTRALISING: Activated coal reduces the formation of unpleasant odours in the shoe.
• ANTIBACTERIAL: Activated coal prevents the development and spreading of fungi and other bacteria.
• BREATHABLE: The PU foam's open cell structure improves the shoe's climate.

An insole provides the connection between the upper and the sole. The ESD compatible soft-fleece insole protects against electrostatic discharge (electrostatic discharge = ESD), even when 100% dry, even without the use of additional aids. The insole's good moisture absorption provides a comfortable foot climate and high degree of wearing comfort. These insoles are approx. 50% lighter than comparable soles made from natural materials and more flexible and more resistant to impact. They breathe well and provide excellent abrasion resistance.

Ethylene vinyl acetate, EVA is an insulating foam that does not absorb water. EVA is elastic and tear and slip-resistant. When used to make shoes, EVA is used as cushioning in the midsole

Fashmo^TM fabric is a water-repellent polyamide microfibre. Fashmo is easy to take care of, breathable and extremely tear-resistant. The fibre is extremely fast drying.

The FG (German: Fuß-Gerecht, "fits the foot") footbed with a permanently formed ankle support and a rounded heel provide the foot with support and control.

This standard defines minimum requirements and methods of testing for the use of three types of shoes for firefighters: shoes for general use when on firefighting duty, shoes worn when fighting fires and shoes worn when working with hazardous materials.

Fit describes the width, height and length of the inside of the shoe. The ball angle, toe length and ball and heel widths are also decisive.

The inlay sole is made from fleece which provides good moisture absorption and release. The material is particularly sturdy. The inlay sole is also replaceable.

Fleece warm lining breathes well and is particularly comfortable on the skin. It can also absorb a large amount of perspiration.

The inlay sole is replaceable, antistatic and sturdy.

The flexrange is found on the heel side of the boot. It is this feature that provides the wearer with the greatest possible flexibility and freedom of movement when kneeling or climbing. It protects the Achilles tendon.

In the course of developing the ERGO-ACTIVE system, ELTEN also developed three fit options, in turn subdivided into three foot types.

Foot type 1: for large feet, short toes, wide ball and heel widths, steep ball angle
Foot type 2: for feet of average width, long toes, average ball and heel widths, flat ball angle
Foot type 3: for narrow feet, with average toe lengths, narrow ball and heel widths, ball angle between steep and flat.

EN ISO 17249 is the European and international standard that specifies the requirements to be fulfilled by safety shoes intended to protect against chainsaw cuts (forest).

In accordance with EN ISO 20345, a low shoe because the vertical distance between the insole's lowest point and the upper's highest point is less than 113 mm for shoe sizes 41 and 42.

In accordance with EN ISO 20345, a laced boot because the vertical distance between the insole's lowest point and the upper's highest point is at least 113 mm for shoe sizes 41 and 42.

In accordance with EN ISO 20345, a high boot because the vertical distance between the insole's lowest point and the upper's highest point is at least 178 mm for shoe sizes 41 and 42.

In accordance with EN ISO 20345, an extremely high boot because the vertical distance between the insole's lowest point and the upper's highest point is at least 280 mm for shoe sizes 41 and 42.

The French point (also know as the Paris point) is 2/3 cm long, i.e. every increase in shoe size corresponds with an increase of 2/3 cm. French shoe sizes begin at 10.

The front support is intended as an aid to be used on ladders or when climbing ladders to prevent slipping from the ladder's rungs.

A full bellows tongue prevents dirt from getting into the shoe

Full-grain cowhide is prepared from the skin layer facing the hair side of the leather. When processed or split, the flesh side is worked and the grain side stays on the outside.

This special full-grain leather is calcium chloride resistant. This leather upper is particularly suited for safety shoes used in mining.

Leather that still has the complete grain layer after processing, i.e. the grain layer is not corrected.

Inlay soles support the longitudinal and transverse arches of the foot. They are often replaceable and as a rule provide good cushioning and optimal shock absorption. At the same time, they may not change the contact resistance (see ESD). Every shoe is tested with an inlay sole when the type examination is done.
