Perforation-proof sole created with overlapping layers of special fabrics. The use of these materials ensures high resistance, as well as light weight and flexibility. This sole has the advantage of covering the entire surface of the foot-bed, therefore providing total foot protection. K SOLE is a non-metal sole.

TPU heel protection technology ensuring stability, comfort and always natural movements.

Special patented technology which uses less rubber, thus reducing the weight of the tread by 20%.

Highly abrasion-resistant thermoplastic polyurethane (TPU) toe cover. Makes the shoe last longer by protecting the toe from direct impacts.

Light, resistant and thin aluminium alloy toe cap to guarantee maximum safety with minimum bulk.

High-performance nitrile rubber tread, thermal contact resistance up to 300°C for one minute, and oil and hydrocarbon resistance.

This trasparent thermoplastic plyurethane film totally wraps the EVA and PU insole, guarateeing excellent resistance to abrasion and ensuring that the footwear last much longer over time. In compliance with CEI EN 61340-5-1:2016 / CEI EN 61340-4-5:2006 / CEI EN 61340-4-3:2002.

Fast lacing system with rotor for micrometric adjustment and steel cable, with Diadora customisation.

Cushioning, energy return and long-lasting performance. Born from the Diadora research, Mass Damper is the new frontier of safety in the workplace. Mass Damper is a revolutionary technology that guarantees total cushioning and energy return while offering maximum protection, versatility and top quality performances over time for the new generation of safety shoes. To feel more energised and less tired at the end of a long day. The low-density material of the sole ensures great resilience and compression set performances, for maximum comfort and a high energy return. The coating creates an external protection shell that increases the sole resistance to abrasion, tearing, hydrolysis, fuels and oil. In addition, it serves to provide stability during the energy release phase. The Mass Damper technology extends to cover the whole surface of the sole, distributing the body weight evenly and allowing the foot to comfortably roll.

Matryx is a multi-zone technical fabric made from aramid fiber and extra-tough polyamide developed by Chamatex®, a French company which is specialized in high performance technical fabrics. Matrix 2.0 is an exclusive patented fabric, specifically designed in close collaboration with Diadora in order to meet the needs of the workplace. With resistance to abrasion, lateral support and high flexibility, Matryx® 2.0 enables professionals to work without sacrificing on comfort.

A sliding lacing system that allows uniform lacing that wraps around the foot without creating pressure points.
