Abstract

A footwear includes an outsole and an insole. The outsole includes multiple support portions connected to an annular peripheral portion, and cooperating with a hole-defining surface to define multiple block-receiving holes, and an annular inner ridge extending from the hole-defining surface into the holes. The insole includes multiple wearproof blocks and an insole body formed with an annular outer groove and multiple embedding grooves between adjacent pairs of the wearproof blocks. The insole body is supported by the support portions and the peripheral portion with the inner ridge received in the outer groove, the support portions received in the embedding grooves, and the wearproof blocks received fittingly in the holes.

Claims

1. A footwear comprising:

an outsole including an annular peripheral portion that has a hole-defining surface, a plurality of support portions that respectively extend in directions substantially perpendicular to a longitudinal direction of said footwear, that are each connected at two ends to said annular peripheral portion, and that cooperate with said hole-defining surface of said annular peripheral portion to define a plurality of block-receiving holes, and an annular inner ridge that protrudingly extends from said hole-defining surface of said annular peripheral portion into said block-receiving holes;

an insole including an insole body that is formed with an annular outer groove, and a plurality of wearproof blocks that are connected to said insole body, said insole being formed with a plurality of embedding grooves between adjacent pairs of said wearproof blocks, said insole body being supported by said support portions and said annular peripheral portion with said annular inner ridge received fittingly in said annular outer groove, said support portions received respectively and fittingly in said embedding grooves, and said wearproof blocks received respectively and fittingly in said block-receiving holes, such that said wearproof blocks protrude from a bottom side of said annular peripheral portion; and

an upper fixed on said outsole.

2. The footwear as claimed in claim 1, wherein one of said support portions that is disposed proximate to a middle section of said annular peripheral portion is greater in size than the remaining one (s) of said support portions.

3. The footwear as claimed in claim 1, wherein each of said embedding grooves has two inner recessed portions respectively concaved in forward and rearward directions such that said embedding groove has a restricted opening at a bottom side of said insole, and each of said support portions includes two engaging protrusions that respectively and protrudingly extend in the forward and rearward directions and that respectively and embeddingly engage said inner recessed portions of the respective one of s aid embedding grooves.

4. The footwear as claimed in claim 2, wherein each of said support portions other than said one of said support portions protrudes downwardly from said bottom side of said annular peripheral portion and from said one of said support portions.

5. The footwear as claimed in claim 1, wherein said upper includes an annular bottom piece sewn to said bottom side of said annular peripheral portion, and an upper piece connected to said annular bottom piece and disposed above said annular peripheral portion.

6. The footwear as claimed in claim 2, wherein said upper includes an annular bottom piece sewn to said bottom side of said annular peripheral portion, a connecting piece sewn to said one of said support portions and connected to said annular bottom piece, and an upper piece connected to said annular bottompiece and disposed above said annular peripheral portion.

7. The footwear as claimed in claim 1, wherein said insole is further formed with a plurality of first draining holes extending through said insole body and said wearproof blocks.

8. The footwear as claimed in claim 7, wherein said support portions of said outsole are formed with at least one first through hole, and said insole body is further formed with at least one second through hole registered with and in spatial communication with said first through hole.

9. The footwear as claimed in claim 1, wherein said insole body and said wearproof blocks of said insole are made of different materials and are molded as one piece.
