ABSTRACT:
In a safety shoe provided with a toecap, a vamp, an insole, and a two-layer structure sole, the a two-layer structure sole includes an outsole part comprising a high hardness rubber material and a midsole part, laminated in the above outsole part, comprising a low hardness sponge rubber material and has a heel part. The outsole part is fused integrally with the midsole part by vulcanization molding, and the upper circumferential edge of the outsole part is fused integrally with the lower circumferential edge of the vamp by the vulcanization molding described above. Since the outsole part in a side in contact with the ground has a high physical strength and is excellent in an oil resistance, a chemical resistance and a heat resistance, and the midsole part in an inner side has a cushioning property, the shoe is less liable to bring about fatigue even after wearing it for a long period of time. Further, a weight of the whole safety shoe can be lightweight, and a durability of the whole safety shoe can be elevated.
