Safety Shoes

The present disclosure relates to safety shoes worn on the feet of a wearer.

Safety shoes used in industrial sites come in many different types depending on their purpose.

In general, safety shoes refer to shoes used to protect the feet from falling objects in factories or construction sites, or to prevent the front part of the foot from being injured when it is hit by a very sharp or hard object while walking.

In particular, safety shoes used at construction sites need to have a very thick outer shell to protect the feet from injury caused by heavy objects falling on the feet or to absorb impact from falling objects, and the thickness of the outer shell is determined by industrial safety regulations.

Additionally, the sole materials, such as the outsole and midsole, need to be thick enough to protect the feet from sharp or pointed objects on the floor.

For this reason, the outer shell of the safety shoes is made of a hard material to safely protect the feet in terms of the overall structure of the shoes, and the sole materials need to also be made of a soft and compressive material to ensure mobility while taking thickness into account.

As described above, the safety shoes are generally made very thick, which makes them much less comfortable for a wearer compared to regular shoes.

In particular, the hard outer shell of the safety shoes can cause the wearer to feel stuffy, leading to discomfort and even pain in the feet when worn for a long period of time.

Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and one objective of the present disclosure is to provide safety shoes that can prevent foot pain and injury and improve wearer's wearing comfort by securing a space for movement of the little toe through an internal space of a protrusion portion.

According to one aspect of the present disclosure, there is provided a safety shoe worn on a foot of a wearer, the safety shoe including: an insole on which the foot of the wearer rests; an outsole provided under the insole to form a bottom of the safety shoe; an outer shell provided on the outsole to cover the foot and forming a shape of the safety shoe; and a protruding member provided on an inner side of the outer shell so as to be disposed at a position corresponding to a little toe of the foot, and protruding convexly outward to form an internal space therewithin for allowing movement of the little toe within the internal space.

According to another aspect of the present disclosure, there is provided a safety shoe worn on a foot of a wearer, the safety shoe including: an insole on which the foot of the wearer rests; an outsole provided under the insole to form a bottom of the safety shoe; a toe cap provided inside a front toe part of the safety shoe and disposed in front of a little toe of the foot; an outer shell provided on the outsole to cover the toe cap and the foot and forming a shape of the safety shoe; and a protruding member provided on an inner side of the outer shell so as to be disposed at a position corresponding to the little toe, and protruding convexly outward to form an internal space therewithin for allowing movement of the little toe within the internal space.

According to another aspect of the present disclosure, there is provided a safety shoe worn on a foot of a wearer, the safety shoe including: an insole on which the foot of the wearer rests; an outsole provided under the insole to form a bottom of the safety shoe; an outer shell provided on the outsole to cover the foot and forming a shape of the safety shoe; a toe cap provided inside a front toe part of the safety shoe, and having a concave portion formed concavely in a forward direction at a position corresponding to a little toe of the foot; and a protruding member located on an outer side of the concave portion on an inner side of the outer shell so as to be disposed at a position corresponding to the little toe of the foot, and protruding convexly outward to form an internal space therewithin for allowing movement of the little toe within the internal space.

Additionally, the safety shoe may further include: a coupling member having a convex portion having a shape corresponding to the concave portion and fitted into the concave portion, and disposed behind the toe cap to be coupled to the toe cap. The protruding member may be located on an outer side of the convex portion.

Additionally, the outer shell may protrude convexly outward by the protruding member.

Additionally, the protruding member may include: a protrusion portion having the internal space therewithin and formed convexly outward; a rim portion provided along at least a part of a perimeter of the protrusion portion; and a joint portion formed by a region where the protrusion portion and the rim portion are connected to each other. The joint portion may be formed to be entirely closed.

Additionally, the protrusion portion may have a pentagonal shape, and the joint portion may be composed of five surfaces corresponding to the pentagonal shaped protrusion portion.

Additionally, the protruding member may include: a protrusion portion having the internal space therewithin and formed convexly outward; a rim portion provided along at least a part of a perimeter of the protrusion portion; and a joint portion formed by a region where the protrusion portion and the rim portion are connected to each other. A region excluding a rear part of the joint portion may be closed, and the rear part of the joint portion may be open.

Additionally, the protrusion portion may have a pentagonal shape, and the joint portion may be composed of four surfaces excluding a rear part of the pentagonal shape.

According to another aspect of the present disclosure, there is provided a safety shoe worn on a foot of a wearer, the safety shoe including: an insole on which the foot of the wearer rests; an outsole provided under the insole to form a bottom of the safety shoe; a toe cap provided inside a front toe part of the safety shoe, and having a protrusion portion protruding convexly outward at a position corresponding to a little toe of the foot to form an internal space therewithin for allowing movement of the little toe within the internal space; and an outer shell covering the toe cap and forming a shape of the safety shoe.

Additionally, the protrusion portion may further include a joint portion formed at a rear end of a little toe side wall and formed by a region where the protrusion portion and the little toe side wall are connected to each other. A region excluding a rear part of the joint portion may be closed, and the rear part of the joint portion may be open.

Additionally, the toe cap and the protrusion portion may be made of different materials.

According to another aspect of the present disclosure, there is provided a safety shoe worn on a foot of a wearer, the safety shoe including: an insole on which the foot of the wearer rests; an outsole provided under the insole to form a bottom of the safety shoe; an outer shell provided on the outsole to cover the foot, forming a shape of the safety shoe, and having a protrusion portion disposed at a position corresponding to a little toe of the foot, formed on an inner side thereof, and protruding convexly outward to form an internal space therewithin for allowing movement of the little toe within the internal space.

Additionally, the safety shoe may further include: a toe cap provided inside a front toe part of the safety shoe, and having a concave portion formed concavely in a forward direction at a position corresponding to the little toe of the foot.

The protrusion portion may be located on an outer side of the concave portion.

Additionally, the safety shoe may further include: a soft member provided in the internal space.

According to safety shoes according to the present disclosure, the following effects are achieved.

By securing a space for movement of the little toe, it is possible to prevent the little toe from touching an inner side of an outer shell or an inner side of a toe cap and feeling pain or getting injured.

By providing a protrusion portion, it is possible to protect the little toe from external impact.

By providing a soft member, it is possible to prevent the little toe from directly touching an inner side of the protrusion portion, thereby improving wearing comfort.
