Heckel MACASPHALT lace-up boot S3 FO HI HRO

Heckel MACASPHALT – ideal for road surfacing work

The Heckel MACASPHALT safety boot is ideal for those working in extreme conditions faced by highway maintenance and road construction workers. Unlike other outdoor industries where safety footwear with a deep tread is recommended to cope with muddy and steep terrain, working with new roadsurfaces requires an outsole with a smoother profile to avoid leaving marks in the material. The MACASPHALT MACSOLE® rubber sole is resistant to contact heat up to 300°C (HRO) and provides good insulation to heat (HI certified). This means the temperature inside the boot does not increase by more than 22°C when subjected to a temperature of 150°C for 30 minutes.
