Steel safety toe-cap that provides total foot protection in the event of objects falling from heights from impacts of up to 200J, which is equivalent to the energy caused by a stone of 10kg from a height of 2m.

Anti-puncture midsole made of high-strength and highly flexible synthetic polymer fiber. It contributes to high thermal insulation of the shoe. Extremely light and comfortable, the high flex midsole guarantees total protection of the foot from the risk of wounds, cuts and punctures. 

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’.

Soles that repel and do not absorb oily substances, and  maintain their characteristics and performances. The test is performed by an immersion in Trimethylpentane. The volume must not increase more than 12%.

Work shoes marked S1-S2-S3 have anti-static properties. They permit low voltage current passage, thus discharging the electrostatic loads accumulated by the operator.

Thanks to a special treatment the uppers are waterproof. The test is performed by sealing the shoe and by immersing it in al water bath after introducing compressed air. Lack of air bubbles indicates that the upper is waterproof.
