The Sir Safety MB3230 B0 safety boot features a nano-fiberglass toe cap and an NWT midsole, which is exceptionally lightweight and flexible. The upper is made of Action Nubuck leather, and the footwear contains no metal components. The S3S protection class is accompanied by FO, HRO and SR certifications.
The tongue has side guards that prevent dirt from getting in, while the lace eyelet area has a seamless, heat-welded reinforcement. The SIR 3D-TEX lining is made of polyester fabric with a honeycomb structure and a reinforced heel area, helping ventilate the foot and reduce sweating. The removable insoles, made from recycled polyurethane foam, feature multiple perforations and help relieve foot fatigue.
