High-resistance TEXTILE anti-perforation midsole. Protects the foot from penetration by dangerous and sharp objects. At the same time, it ensures maximum flexibility and lightness for the foot.
COMPOSITE toe cap resistant to impacts up to 200 Joules, lightweight and metal-free, ideal for safely protecting the toes without adding weight to the footwear.
Unlike other materials, composite offers several advantages: thermal insulation (does not transmit heat), non-magnetic (not detected by metal detectors), and memory (in case of compression, it returns to its original shape, leaving toes free).

The Anti Torsion system uses a thermoplastic shank designed to increase stability on irregular and wet surfaces. Unlike standard shanks, it flexes with the foot’s natural motion, reducing the risk of twists and falls. Ideal for outdoor work, especially in construction, where surface control is critical.
Technical materials
Three to Be® - Tripla Densità Iniettata technology represents one of the most advanced results of our R&D efforts. Patented by Giasco, it integrates three entirely polyurethane-injected sole layers to optimize safety shoe performance in terms of comfort, stability, and slip resistance.
