Protective toe cap (impact resistance) (200±4)J after impact energy, the toe gap is greater than 15mm, anti-smash (pressure resistance) (15±0.1)kN pressure, protects the inside of the toe cap The minimum distance is greater than 15mm, and the force required to resist puncture and penetrate the shoe (boot) sole is ≥1100N (special grade). If the labor protection shoes transported in the workshop need to achieve these functions at the same time, the general weight will be around 1.2KG.
