This application claims priority of Taiwanese Patent Application No. 102207227, filed on Apr. 19, 2013.
1. Field of the Invention
The invention relates to a footwear, more particularly to a footwear suitable for water sports and/or water activities.
2. Description of the Related Art
A conventional shoe for wading as disclosed in Taiwanese Patent No. 373450 includes a sole, an upper integrated with a top portion of the sole, and an anti-slipping mat integrated with a bottom portion of the sole. If the upper and the anti-slipping mat are glued to the sole, the glue will gradually lose its adhesive strength after the conventional shoe has been soaked in water, thus shortening the service life of the conventional shoe. If the upper and the anti-slipping mat are to be sewn to the sole, due to the overall thickness of the conventional shoe, the sewing process would be rather difficult.
Another conventional shoe for wading as disclosed in Taiwanese Patent No. M377900 includes an insole that is stacked on and fixed to a top portion of an outsole with adhesive which will also gradually lose its adhesive strength after the conventional shoe has been soaked in water, thus shortening the service life of the conventional shoe. If sewing is used instead, the result is similar to that of the conventional shoe previously mentioned. Therefore, these conventional shoes could only be made into “flip-flops,” limiting the functionality and wearing stability thereof, especially during water sports and/or activities, where the conventional shoe is likely to slide off a user's foot and possibly get lost.
Therefore, the object of the present invention is to provide a shoe that can eliminate the aforesaid drawbacks of the prior art.
According to the present invention, there is provided a footwear suitable for water sports/activities that includes an outsole, an insole and an upper.
The outsole includes an annular peripheral portion, a plurality of support portions and an annular inner ridge. The annular peripheral portion has a hole-defining surface. The support portions respectively extend in directions substantially perpendicular to a longitudinal direction of the shoe, are each connected at two ends to the annular peripheral portion, and cooperate with the hole-defining surface of the annular peripheral portion to define a plurality of block-receiving holes. The annular inner ridge protrudingly extends from the hole-defining surface of the annular peripheral portion into the block-receiving holes.
The insole includes an insole body formed with an annular outer groove and a plurality of wearproof blocks connected to the insole body. The insole is formed with a plurality of embedding grooves between adjacent pairs of the wearproof blocks. The insole body is supported by the support portions and the annular peripheral portion with the annular inner ridge received fittingly in the annular outer groove, the support portions received respectively and fittingly in the embedding grooves, and the wearproof blocks received respectively and fittingly in the block-receiving holes. The upper is fixed on the outsole.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
Referring to
The outs ole 10 includes an annular peripheral port ion 11, a plurality of support portions 13, and an annular inner ridge 113.
The annular peripheral portion 11 has a hole-defining surface 111. The support portions 13 respectively extend in directions substantially perpendicular to a longitudinal direction of the footwear, are each connected at two ends to the annular peripheral portion 11, and cooperate with the hole-defining surface 111 of the annular peripheral portion 11 to define a plurality of block-receiving holes 141. The annular inner ridge 113 protrudingly extends from the hole-defining surface 111 of the annular peripheral portion 11 into the block-receiving holes 141. One of the support portions 13A that is disposed proximate to a middle section of the annular peripheral portion 11 is greater in size than the remaining one(s) of the support portions 13B. Each of the support portions 13B protrudes downwardly from the bottom side of the annular peripheral portion 11 and from the support portion 13A.
Further referring to
In this embodiment, each of the embedding grooves 23 has two inner recessed portions 231 respectively concaved in forward and rearward directions such that the embedding groove 23 has a restricted opening at a bottom side of the insole 20. Each of the support portions 13 includes two engaging protrusions 133 that respectively and protrudingly extend in the forward and rearward directions and that respectively and embeddingly engage the inner recessed portions 231 of the respective one of said embedding grooves 23.
In addition, the insole 20 is further formed with a plurality of first draining holes 24 extending through the insole body 21 and through the wearproof blocks 22. The support portions 13 of the outsole 10 are formed with at least one first through hole 132, and the insole body 21 is further formed with at least one second through hole 212 registered with and in spatial communication with the first through hole 132, thus cooperatively forming at least one second draining hole 25 in the insole 20.
The upper 30 is fixed on the outsole 10, and includes an annular bottom piece 31 sewn to the bottom side of the annular peripheral portion 11, a connecting piece 32 sewn to the support portion 13A and connected to the annular bottom piece 31, and an upper piece 33 connected to the annular bottom piece 31 and disposed above the annular peripheral portion 11.
Before the insole 20 is assembled to the outsole 10, the annular bottom piece 31 and the connecting piece 32 of the upper 30 are sewn to the annular peripheral portion 11 and the support portion 13A.
With reference to
Accordingly, the advantages of the present invention are summarized as follows:
