a side plate formed to extend downwards from the top plate and to surround the top plate;
a bottom plate formed to be under the side plate and to cover a bottom surface of the front of the work shoe; and
an anti-separation means for preventing separation of the attachable/detachable toecap from the work shoe,
wherein the anti-separation means further comprises a plurality of vertically perforated coupling grooves, wherein the coupling grooves are formed to be at a position overlaying to a plurality of coupling blocks protruding from the bottom surface of the work shoe, so that the plurality of coupling blocks are snap-fitted to the coupling grooves to prevent the separation of the attachable/detachable toecap from the work shoe,
wherein the coupling blocks are formed to be divided by a plurality of groove lines at the bottom of the work shoe,
wherein the coupling grooves are formed to be divided by a plurality of bottom lines formed at the bottom plate, and
wherein the plurality of bottom lines further comprises:
a first bottom line formed to connect a first point at one side of the bottom plate and a second point at another side of the bottom plate;
a second bottom line formed to be inclined upward at a neighboring position of the first bottom line apart from the first bottom line by a predetermined distance and to connect a third point, which is spaced apart from the first point at one side of the bottom plate, and a fourth point, which is spaced apart from the second point at another side of the bottom plate;
a third bottom line formed to connect the first bottom line and the second bottom line; and
a fourth bottom line formed to connect the second bottom line and a fifth point at still another side of the bottom plate.
