## Abstract

Disclosed is a non-slip footwear which comprises a main body formed of a flexible material and formed to surround the sole of a foot of a user and to open the top side of the foot; toe insertion holes formed of the flexible material, protruding from the front part of the main body so that toes of the foot are respectively inserted into the toe insertion holes; an non-slip outsole formed at the heel part of the main body and formed of foamed rubber having abrasion resistance, and having a thickness of 1 mm˜5 mm; and non-slip dots formed at the sole part of the main body and the non-slip outsole.

## Claims

### Claim 1

Non-slip footwear comprising:
a main body formed of a flexible material and formed to surround the sole of a foot of a user and to open the top side of the foot;
toe insertion holes formed of the flexible material, protruding from the front part of the main body so that toes of the foot are respectively inserted into the toe insertion holes;
an non-slip outsole formed at the heel part of the main body and formed of foamed rubber having abrasion resistance, and having a thickness of 1 mm˜5 mm; and
non-slip dots formed at the sole part of the main body and the non-slip outsole,
wherein toe corrective inserts formed of silicon and having elasticity and shape stability are formed at areas between the toes of the toe insertion holes.

### Claim 2

Non-slip footwear comprising:
a main body formed of a flexible material and formed to surround the sole of a foot of a user and to open the top side of the foot;
toe insertion holes formed of the flexible material, protruding from the front part of the main body so that toes of the foot are respectively inserted into the toe insertion holes;
an non-slip outsole formed at the heel part of the main body and formed of foamed rubber having abrasion resistance, and having a thickness of 1 mm˜5 mm; and
non-slip dots formed at the sole part of the main body and the non-slip outsole,
wherein the flexible material is a synthetic fiber having flexibility,
wherein toe corrective inserts formed of silicon and having elasticity and shape stability are formed at areas between the toes of the toe insertion holes.

### Claim 3 (depends on 1)

The non-slip footwear according to claim 1, wherein acupressure protrusions protrude from the inner surface of the main body.

### Claim 4

Non-slip footwear comprising:
a main body formed of a flexible material and formed to surround the sole of a foot of a user and to open the top side of the foot;
toe insertion holes formed of the flexible material, protruding from the front part of the main body so that toes of the foot are respectively inserted into the toe insertion holes;
an non-slip outsole formed at the heel part of the main body and formed of foamed rubber having abrasion resistance, and having a thickness of 1 mm˜5 mm; and
non-slip dots formed at the sole part of the main body and the non-slip outsole,
wherein the front parts of the toe insertion holes are opened so that the front parts of the toes protrude outward from the non-slip footwear,
wherein toe corrective inserts formed of silicon and having elasticity and shape stability are formed at areas between the toes of the toe insertion holes.

### Claim 5 (depends on 1)

The non-slip footwear according to claim 1, wherein bending parts having elasticity are formed at the end of the top part of the main body and the ends of the front parts of the toe insertion hole.

### Claim 6 (depends on 2)

The non-slip footwear according to claim 2, wherein acupressure protrusions protrude from the inner surface of the main body.

### Claim 7 (depends on 2)

The non-slip footwear according to claim 2, wherein the front parts of the toe insertion holes are opened so that the front parts of the toes protrude outward from the non-slip footwear.

### Claim 8 (depends on 2)

The non-slip footwear according to claim 2, wherein bending parts having elasticity are formed at the end of the top part of the main body and the ends of the front parts of the toe insertion holes.
