Chain saw cut resistance

Some footwear models offer chainsaw cut resistance in accordance with EN ISO 17249:2013. Yet, please note that no personal protective equipment can provide 100% protection against cuts from portable chainsaws. However, experience has shown that it is possible to design equipment that offers a certain degree of protection. Several functional principles that can be employed to provide protection include:

• sliding of the chain on contact, so that it cannot cut the material;
• accumulation of fibres which, when entering the chain gears, cause them to stop;
• slowing down of the chain by means of fibres with high cutting resistance capable of absorbing the rotation energy, thus reducing the speed of the chain.

Flame retardant and heat resistance

High level of heat insulation: all Jolly footwear in the ‘Fire’ collections reach the HI_³ level with average values 30% higher than the requirements of the EN15090:2012 standard. Resistance to radiant heat greatly exceeds the minimum requirements of EN15090:2012.

Anti-perforation

In addition to the traditional metal laminate, Jolly Scarpe uses composite anti-perforation insoles with a structure in multilayer fabrics made with a special anti-perforation material and compliant with "Zero mm" Perforation at 1100 Newton according to the EN 12568:2010 and 22568:2019 standards. The anti-perforation fabric insoles, as opposed to the traditional metal plates, offer considerable ergonomic and safety advantages.

The old EN 12568:2010 standard required penetration resistance to a 4.5mm nail diameter. The new EN ISO 22568:2019 standards allow footwear to be marked PL (resistance to a 4.5mm nail) or PS (resistance to a 3mm nail).

SR Certification

The risk of slipping is one of the main causes of accidents in the workplace, a figure widely reported by various studies both at European and international level. For this reason, the reference standards for footwear provide for this mandatory test. The EN ISO 20345:2011 and EN ISO 20347:2012 standards provide for the possibility of verifying the friction coefficient on two types of surfaces (steel and ceramic), with the attribution of 3 different levels of performance, as summarised in the graph:

SRC (SRA + SRB)
Almost all Jolly shoes meet the strictest SRC requirement, thanks to the specific study of the tread and sole compounds, in order to offer maximum protection to the end user.

SRA
Surface: standard ceramic
Lubricant: water+detergent

SRB
Surface: steel
Lubricant: glycerine

With the new 20347 and 20345:2022 standards, the test standards have become even more demanding:

the slip test on a ceramic surface with water lubricant + detergent has become a mandatory requirement for any footwear.
The previous test performed on steel surface and glycerin lubricant, since it was no longer considered representative of risk situations, was instead replaced by the one performed on ceramic with glycerin lubricant. Passing the latter allows the SR shoe to be marked, the ultimate protection against slipping. The minimum passing requirements were raised for all test conditions, and the procedure was also modified, increasing the focus on the risk of slipping in the toe area of the shoe.

Mandatory anti-slip test:
Surface: standard ceramic
Lubricant: water + detergent
SR marking (optional):
Surface: standard ceramic
Lubricant: glycerine

Quick-Release split zipper

The lacing system with the Quick-Release divisible zipper allows for maximum adjustment and precision of the lacing, as well as ease of releasing it. Adjustment, precision, release, these are the 3 elements that form the fulcrum of the application of ergonomics know-how to the concept of safety and are the result of constant relationships with end users.

The completely divisible zip also allows cleaning of the boot even in the points that were inaccessible with traditional closures. The replaceable slider means longer life of the hinge element and savings in accessory elements.

Ankle support

Many shoes in our collection feature an ankle protection insert. We have inserted a rigid malleolus protection in order to adequately support the ankle and limit the risk of sprains in combination with specific cushioning material to disperse and cushion the force caused by harmful impacts.

The shoulder pad is tested according to EN ISO 20345:2011 or EN ISO 20345:2022 and must return an average force after impact of less than 10 kN. The new EN ISO 20345:2022 standard has introduced new specific positioning requirements, which take more account of the anatomy of the bones of the foot.

• Asymmetrical with load-bearing base
• Tested and certified according to EN12568:2010 e EN22568:2019 standards

Energy absorption in the heel

The level of energy absorption is determined by the thickness and composition of the sole, by the height and shape of the heel, by the height and shape of its internal grid which also determines a decrease in weight and the presence of a cushion of air for better thermal insulation, by the composite material of the anti-perforation insole or by the presence of anti-shock inserts in PU or EVA and finally by our shape.

Honey-comb sole

A peculiar element that distinguishes the rubber soles of Jolly footwear is the honeycomb-like internal reticular structure. The air cushion created between the sole and the upper increases the insulation properties in both heat and cold, and also enhances the cushioning function of the heel, thanks to the specific study of the heights of the thicknesses of the rubber lattice. The sole is also lighter and more flexible, as opposed to soles with an internal polyurethane insert which are in fact heavier and more rigid and which can be damaged over 130°C.

Wrap band system

The new sealing system, on the instep area, prevents the boot from being taken off. The system consists of a band, made of elastic material and integral with the insole, which holds the foot in the correct position. The system is particularly suitable for female firefighters. For the selection of the size we always recommend verifying the suitability for use by means of a practical fit test. The shoe meets the safety features only if perfectly worn.

J-Morphic shape

In order to be able to reach the highest level of slip resistance, i.e. the SRC level according to the EN ISO 20345:2011 standard, Jolly has developed a sole based on the new J-MORPHIC shape for its FIRE and SEARCH&RESCUE collections. The new J-Morphic shape, much more rounded than that of traditional boots, aims to be a valid alternative to the classic flat sole that uses anti-perforation metal inserts.

The advantages are as follows:

• the profile is more modern with a much wider toe fit so that the toes are not contracted
• the rounded heel facilitates the support of the foot during the rolling phase avoiding the discomfort caused by sharp surfaces, this also ensures a higher level of slip resistance
• the rounded side for a better rolling movement of the feet with less stress for the gluing of the same and fewer creases in the upper that could cause pressure points on the foot; therefore the walk is much more restful, the feet less stressed and the muscles more relaxed.
• The level of energy absorption is determined by the thickness and composition of the sole, by the height and shape of the heel and by its internal lattice which also determines a decrease in weight and the presence of an air cushion for better thermal insulation, by the composite material of the anti-perforation midsole and finally by our J-MORPHIC shape. These multiple technological aspects make it possible to offer better results in terms of extreme lightness and energy absorption. Most of FIRE and SEARCH&RESCUE Jolly footwear do not require a midsole or PU inserts.

• Greater slip resistance
• Greater comfort
• Better rolling and less stress
• Less weight

Flex system

The padded joints inserted on the back, above the heel, in the intermediate front area as well as in the internal tongue allow the foot to flex correctly in the right points and the possibility of performing a wide range of movements, both when walking even on slopes, and while driving vehicles, or for those who have to go up/down stairs.

Sole Compensator System SCS

Each of us has a different and absolutely personal foot length and volume. To overcome this limit, Jolly has developed SCS (Sole Compensator System): it consists of orthotics of different thicknesses so as to compensate for the volume of the shoe with respect to the volume of the foot. The shoe is supplied with the standard insole, in case of need the thicker SCS EXTRA insole, or the thinner SCS insole are available. In this way, the perfect fit and maximum comfort/stability are ensured.

Waterproof

Waterproofing and transpiration allow for high climatic comfort which is an essential element for adequate operator performance in the context of his/her activity.
The EN ISO 20344:2011 and 20344:2021 standards present a dynamic test method for the water resistance of footwear, the so-called "flex test", with a minimum requirement of 4800 flexes.

High breathability

01. Full Grain Leather
The leathers used for most of our uppers are of the "full grain" type, i.e. the most valuable part of the skin. The special tanning treatments give the leather the necessary water repellency combined with excellent breathability.

02. Cordura
Synthetic fabric with good characteristics of resistance and breathability. It finds application in footwear not subjected to heavy operational stress.

Internal ventilation system

The EN15090 standard for firefighters’ footwear establishes that the upper is the entire height of the shoe, consequently all tests (resistance to tearing, radiant heat, flame, water penetration and absorption) must be performed on the entire surface of the upper itself. Jolly footwear for firefighters are built to offer maximum protection, for this reason with our ventilation system the air between the upper and the GORE-TEX lining flows easily from inside to outside and vice versa through the mesh internal collar that breathes naturally at every step.
