The 561 is our toughest boot, designed with a higher cut for added coverage and manufactured with a full leather upper. Bearing the mighty Vibram® sole, this boot can withstand temperatures up to 300°C. The exterior may be fortified but look no further for comfort as the interior of the boot includes the OrthoTec Poron® footbed which enhances comfort with its shock absorbing properties and anatomical arch support. This boot is a confident choice for boiler makers, miners, grinders, road workers or anyone who needs protection from the heat.
