Insole having puncture-resistant properties for safety footwear

摘要

A insole (1) having puncture-resistant properties for safety footwear, comprising an anterior portion (2) extending from a toe region (3) to a metatarsal region (4) of the insole and a posterior portion (5) extending from the metatarsal region to a heel region (6) longitudinally opposite the toe region. The posterior portion (5) comprises at least one substantially rigid layer (8) made of composite material formed from a fibre-reinforced polymer matrix and the anterior portion (2) is formed of a substantially flexible material comprising at least one layer (7) formed of polymer fibres having enhanced puncture-resistant properties.
