Derby leather work shoes are ESD safety shoes from the Light Work Kapriol line, designed for those seeking lightweight, dynamic, and stylish footwear. ESD certification guarantees the dissipation of electrostatic charges, making them ideal for work in contact with electronic components, electronically controlled machinery, and in laboratories. The full-grain leather upper ensures durability and a professional appearance, while the padded tongue and collar guarantee all-day comfort. The toe reinforcement protects the shoe in high-wear areas, and the double-density polyurethane sole provides lightness and grip, weighing just 555 g in size 42.

Certified S3S FO SR ESD according to the EN ISO 20345:2022+A1:2024 standard, Derby safety shoes combine protection, lightness, and elegance in every work environment. This model is also available in a version with a Mesh upper.

Technology

Light safety toe cap
Synthetic material insole
PU-PU Sole
Extra Comfort

Light safety toe cap

Particularly lightweight composite toe cap that provides high thermal insulation and total foot protection in the event of objects falling from above, from impacts of up to 200J, which is equivalent to the energy caused by a stone of 10kg from a height of 2m.

Synthetic material insole

Synthetic puncture-resistant insole: lighter and more flexible than a steel insole, it protects the entire surface of the plant of the foot  providing greater comfort in all conditions.

PU-PU Sole

Polyurethane gives the sole lightness and flexibility. It has shock-absorbing features that guarantee high comfort for the entire shoe. The double injection of polyurethane makes it possible to obtain dual-coloured or dual-density soles. Polyurethane is injected onto the upper by means of special moulds: these are called ‘injected soles’ or simply ‘injected’.

Extra Comfort

Insole with enhanced cushioning that absorbs impacts and reduces foot fatigue, ensuring maximum well-being even during the longest workdays.

Performance

A - Antistatic Shoe
FO - Resistance of the sole to hydrocarbons
WPA - Upper resistance to water penetration and assorption
ESD - Electrostatic discharge
SR - Slip resistance

A - Antistatic Shoe

Work shoes with antistatic properties that allow the controlled passage of low-voltage currents, dissipating the electrostatic charges accumulated by the operator during work activities and reducing the risk of ignition in environments with the presence of flammable or explosive substances.

FO - Resistance of the sole to hydrocarbons

Work shoes equipped with soles designed to resist prolonged contact with oily substances and hydrocarbons without undergoing structural alterations. The laboratory test involves immersing the compound in Trimethylpentane, verifying that the swelling and increase in volume of the sole do not exceed 12%, thus ensuring the stability and durability of the shoe over time. This requirement is mandatory for work footwear according to the 2011 standard, while it becomes additional and optional for the 2022 standard.

WPA - Upper resistance to water penetration and assorption

Safety shoes equipped with an upper resistant to both water penetration and absorption. The test separately evaluates the amount of water that penetrates through the material and that absorbed by the upper structure after prolonged contact with water.

ESD - Electrostatic discharge

Shoes that constantly discharge the static electricity accumulated by the human body to the ground, also protecting devices that are sensitive to electrostatic discharge.

SR - Slip resistance

Safety shoes equipped with a sole with advanced anti-slip performance, specifically designed to ensure maximum stability and grip even on the most insidious surfaces. Subjected to severe dynamic friction tests under wet and lubricated conditions, this footwear ensures a firm grip on the ground and drastically reduces the risk of accidental falls. It is the ideal solution to guarantee maximum safety on wet or oily floors, typical of critical environments such as professional kitchens, laboratories and food processing plants.
