(54) Outsole of shoes


(57) An outsole includes a front section (21), a mediate section (22) and a rear section (23) on a bottom of the outsole (20). A plurality of first protrusions (31,32) extend from the bottom of the outsole and are respectively arranged along two sides of the front section and the rear section. A first area (41) is located to be enclosed by the first protrusions on the front section and a plurality of second protrusions (43) are located in the first area. A second area (42) is located to be enclosed by the first protrusions (32) on the rear section (23) and a plurality of third protrusions (44) are located in the second area (42). The front section has a flexible section (210) which is perpendicular to a longitudinal axis of the front section and located corresponding to the ball of wearer's foot.




Description

FIELD OF THE INVENTION



[0001] The present invention relates to an outsole having a front portion and a rear portion with a flexible section connected therebetween. Each of the front portion and the rear portion has anti-slip protrusions for providing anti-slip feature.

BACKGROUND OF THE INVENTION



[0002] A conventional outsole 10 for shoes is shown in Fig. 1 and generally is a thick and one-piece member which has a heel portion 12 attached to a rear section of the outsole 10, and patterns 11 extending from a front section of the outsole 10. The thick outsole 10 has less flexibility and is usually stiff so that it is not satisfied by the wearers. Besides, the conventional outsole 10 is made by the same material so that it has an identical stiffness which makes the outsole 10 to be not able to meet the complicated deformation requirements of outsole when the wearers walk or run on roads with differernt conditions. This conventional outsole 10 is slippery when walking on sandy or wet roads.

[0003] The present invention intends to provide an outsole that has anti-slip protrusions which have different stiffness and a flexible section is located corresponding to the ball of wearer's foot so that the outsole is easily bent when the wearers walk.

SUMMARY OF THE INVENTION



[0004] In accordance with one aspect of the present invention, there is provided an outsole and comprises a front section, a mediate section and a rear section on a bottom of the outsole. A plurality of first protrusions extend from the bottom of the outsole and are respectively arranged along two sides of the front section and the rear section. A first area is located between the first protrusions on the front section and a plurality of second protrusions are located in the first area. A second area is located between the first protrusions on the rear section and a plurality of third protrusions are located in the second area.

[0005] The primary object of the present invention is to provide an outsole that has protrusions on a bottom thereof and the stiffness of the protrusions is different so as to have a flexible and anti-slippery outsole.

[0006] Another object of the present invention is to provide an outsole that has a flexible section which is located at the ball portion of the wearer's foot such that the outsole is soft and flexible.

[0007] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT



[0009] Referring to Figs. 2 to 4, the outsole of the present invention comprises a front section 21, a mediate section 22 and a rear section 23 on a bottom of the outsole 20. A plurality of first protrusions 31, 32 respectively extend from the bottom of the outsole 20 and are respectively arranged as a U-shape arrangement along two sides of the front section 20 and the rear section 23. The mediate section 22 is softer than the first protrusions 31, 32. The front section 21 has a flexible section 210 which is perpendicular to a longitudinal axis of the front portion 21 and is located corresponding to the ball portion of wearer's foot so that the outsole is easily bent when the wearers walk.

[0010] A first area 41 is located between two wings of the first protrusions 31 on the front section 21 and a plurality of second protrusions 43 are located in the first area 41. A second area 42 is located between two wings of the first protrusions 32 on the rear section 23 and a plurality of third protrusions 44 are located in the second area 42. The first area 41 and the second area 42 are softer than the second protrusions 43 and the third protrusions 44.

[0011] Further referring to Fig. 5, the first protrusions 31, 32 have anti-slippery function which prevents the wearer from slip when walking on sandy or wet roads. The flexible section 210 allows the outsole to be more flexible when needed. The second protrusions 43 and the third protrusions 44 provides a better grape function on serrated roads. When the outsole is bent, the flexible section 210 the ball portion of the wearer's foot feel comfortable and the softer mediate section 22 let the outsole to be expandable so that the wearer's foot bears less stress.

[0012] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.

[0013] An outsole includes a front section, a mediate section and a rear section on a bottom of the outsole. A plurality of first protrusions extend from the bottom of the outsole and are respectively arranged along two sides of the front section and the rear section. A first area is located to be enclosed by the first protrusions on the front section and a plurality of second protrusions are located in the first area. A second area is located to be enclosed by the first protrusions on the rear section and a plurality of third protrusions are located in the second area. The front section has a flexible section which is perpendicular to a longitudinal axis of the front section and located corresponding to the ball of wearer's foot.
