DETAILED DESCRIPTION

Before the present disclosure is described in greater detail, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.

Referring to FIGS. 1 and 2, a shoe accessory of a shoe adaptive for activating a bottom 1 of a foot wearing the shoe is shown. The bottom 1 of the foot has a forefoot 11, a heel 12, and an arch 13 between the forefoot 11 and the heel 12. The shoe accessory includes a main body 2, a plurality of stimulating elements 3 and a flexible unit 4.

In this embodiment, the main body 2 is an insole of the shoe. The stimulating elements 3 are mounted to the main body 2. Each of the stimulating elements 3 is movable universally on the main body 2, is adapted to exert a pressing force on the bottom 1 of the foot to stimulate the arch 13, and is shaped as one of a sphere, a triangle, a polygon, and an irregular shape.

In this embodiment, the stimulating elements 3 correspond in position to the arch 13, which includes a transverse arch portion, a medial arch portion and a lateral arch portion. Each of the stimulating elements 3 includes a bag wall 31 defining a chamber 30 therein and including a connecting portion 311 and a stimulating portion 312.

For each of the stimulating elements 3, the chamber 30 is deformable to change a contact point between the bottom 1 of the foot and a corresponding one of said stimulating elements 3, and the stimulating portion 312 is adapted to contact the bottom 1 of the foot and to stimulate the bottom 1 of the foot. It should be noted that the chamber 30 may be omitted, so that each stimulating element 3 is configured as a solid sphere shown in FIG. 8.

The flexible unit 4 includes a soft layer 41 fixed on the main body 2, interconnecting the main body 2 and the connecting portion 311 of each of the stimulating elements 3, and being flexible. In this embodiment, the soft layer 41 is made of a deformable material similar to gel, e.g., thermoplastic polyurethanes (TPU). In this embodiment, the stimulating elements 3 are formed integrally with the soft layer 4.

Further referring to FIGS. 3 to 5, when the bottom 1 of the foot is stepped on the shoe accessory, the stimulating elements 3 are deformed due to the fluidity of the soft layer 41 and thus move universally relative to the main body 2 to stimulate the arch 13. The movement of the stimulating elements includes but not limited to moving downwardly, returning to the original position after moving downwardly, shifting along a front-rear direction and a left-right direction transverse to the front-rear direction, and returning to the original position after shifting along the front-rear direction and the left-right direction.

In this way, when the bottom 1 of the foot is stepped on the shoe accessory, the stimulating portion 312 of each of the stimulation elements 3 stimulates the arch 13 to exert a pressing force on muscles of the arch 13 so as to activate the muscles and drive relative movement of toes of the forefoot 11. Thus, the muscles of the foot can be relieved, and blood circulation of the muscles of the foot can be enhanced. In the case that the shoe accessory is used for a long time, discomfort would not be caused to the foot wearing the shoe. Some deep muscles of the foot, small muscles of the calf and the bottom 1 of the foot that are rarely used can be activated by the shoe accessory so as to strengthen the abilities of the arch 13 to absorb shock from ground and to balance. Further, for people having muscle soreness after high-intensity exercise and wearing the shoe accessory of the present disclosure may reduce time for recovery.

It should be noted that the stimulating elements 3 can be moved universally in manners other than flexing and deforming the soft layer 41. For example, as shown in FIG. 6, the stimulating elements 3 are moved universally due to deformation of the main body 2. Additionally, the stimulating elements 3 are moved due to compression by the bottom 1 of the foot in different directions such that the stimulating portions 312 move universally.

Further, the bag wall 31 of each of the stimulating elements 3 may include more than one stimulating portions 312. For example, as shown in FIG. 7, the stimulating elements 3 are modified such that the bag wall 31 of each of the stimulating elements 3 includes a plurality of stimulating portions 312 disposed along a periphery thereof and connected to the soft layer 41 of the flexible unit 4 through the connecting portion 311.

Referring to FIG. 8, a second embodiment of the shoe accessory of the present disclosure is similar to the first embodiment and the difference therebetween resides in the following. In the second embodiment, each of the stimulating elements 3 includes a connecting portion 311′ configured as a bendable pillar and a stimulating portion 312′ connected to the connecting portion 311′ and shaped as a sphere.

The flexible unit 4 includes a soft layer 41′ interconnecting the connecting portion 311′ of each of the stimulating elements 3 and the main body 2, and cooperating with the main body 2 to define a space 40 therebetween. In this embodiment, the soft layer 41′ is a soft plastic sheet that is flexibly deformable through the space 40. In this way, when the bottom 1 of the foot is stepped on the shoe accessory, the stimulating elements 3 are moved universally due to the deformation of the soft layer 41′ and bending of the connecting portions 311′ caused by the force exerted by the bottom 1 of the foot in different positions and directions. Thus, the stimulating portions 312′ of the stimulating elements 3 stimulate the arch 13 (see FIG. 2) at different positions.

Referring to FIG. 9, a third embodiment of the shoe accessory of the present disclosure is shown. In the third embodiment, each of the stimulating elements 3 also includes a connecting portion 311 and a stimulating portion 312. The flexible unit 4 includes a plurality of flexible elements 43 connected respectively to the stimulating elements 3, and connected to the main body 2. In this embodiment, each of the flexible elements 43 is a resilient member such as a compression spring. Thus, when the bottom 1 of the foot (see FIG. 2) is stepped on the shoe accessory, since the flexible elements 43 are deformed by the force exerted by the bottom 1 of the foot in different positions and directions, the stimulating portions 312 of the stimulating elements 3 are moved universally to stimulate and activate the muscles of the arch 13 at different positions.

Referring to FIG. 10, a fourth embodiment of the shoe accessory of the present disclosure is shown. In the fourth embodiment, the flexible unit 4 further includes a plated-shaped flexible plate 44 for supporting the stimulating elements 3 thereon, and a flexible element 45 disposed under and connected to the flexible plate 44, and the stimulating portion 312″ of each of the stimulating elements 3 is shaped as a triangle. In this embodiment, the flexible element 45 is a resilient element such as a compression spring, and is connected between the flexible plate 44 and the main body 2.

The flexible plate 44 of the flexible unit 4 interconnects the stimulating elements 3 and the flexible element 45, and is deformable. Thus, when the bottom 1 of the foot (see FIG. 2) is stepped on the shoe accessory, since the flexible element 45 is deformed by the force exerted by the bottom 1 of the foot in different positions and directions, the stimulating portions 312″ of the stimulating elements 3 are moved universally to stimulate and activate the muscles of the arch 13 at different positions.

Referring to FIG. 11, a fifth embodiment of the shoe accessory of the present disclosure is similar to the first embodiment and the difference therebetween reside in the following. The flexible unit 4 includes a plurality of flexible elements 46 connected to the main body 2 and connecting the stimulating elements 3 in series. In this embodiment, each of the flexible elements 46 is a string element. Thus, when the bottom 1 of the foot (see FIG. 2) is stepped on the shoe accessory, since the flexible elements 46 are deformed by the force exerted by the bottom 1 of the foot in different positions and directions, the stimulating elements 3 connected to the flexible elements 46 are moved universally to stimulate and activate the muscles of the arch 13 (see FIG. 2) at different positions. Note that the flexible elements 46 may connect the stimulating elements 3 together in other manners, for example, a plurality of additional stimulating elements 3 are rotatably and respectively sleeved on corresponding ones of the flexible elements 46.

Referring to FIG. 12, a modification of the fifth embodiment is shown. In this modification, two pairs of flexible elements 46 are connected respectively to two opposite sides of a stimulating element 3, and thus the stimulating element 3 is movable relative to the main body 2 through the deformation the flexible elements 46.

Referring to FIG. 13, a sixth embodiment of the shoe accessory of the present disclosure is similar to the first embodiment and the difference therebetween reside in the following. In this embodiment, the stimulating elements 3 and the flexible unit 4 are integrally formed by a deformable and flexible material such as TPU, in a wavy configuration. The peak portions that are adjacent to the bottom 1 of the foot wearing the shoe constitute the stimulating elements 3, and the valley portions constitute the flexible unit 4. The sixth embodiment possesses the advantages of the first to fifth embodiments.

Referring to FIG. 14, a seventh embodiment of the shoe accessory of the present disclosure is similar to the first embodiment and the difference therebetween reside in the following. In this embodiment, the main body 2 defines an accommodation space 21 adapted to open toward the bottom 1 of the foot and accommodating the stimulating elements 3 therein. The stimulating elements 3 are movably mounted in the accommodation space 21. Thus, the seventh embodiment possesses the advantage of the first to sixth embodiments.

Additionally, in other embodiments, the main body 2 can be one of a midsole, an outsole, and a portion of an upper of the shoe extending toward the outsole of the shoe. For example, when the main body 2 is the outsole of the shoe, an insole and a midsole of the shoe can be modified to have a relatively thin thickness to ensure that the stimulating elements 3 are able to stimulate the bottom 1 of the foot. A person having ordinary skill in the pertinent art is able to make some modifications to the shoe accessory of the present disclosure and further examples are omitted for the sake of brevity.

To sum up, the advantages of the present disclosure are described in the following. By virtue of the stimulating elements 3 that are adapted to stimulate the muscles of the arch 13, the forefoot 11 of the bottom 1 of the foot is activated. Further, since the stimulating elements 3 are movable universally when being stepped on by the bottom 1 of the foot, contact points between the arch 13 and the stimulating elements 3 are frequently changed. That is to say, each of the stimulating elements 3 is movable universally on the main body to exert a pressing force on a non-fixed point of the bottom 1 of the foot to stimulate the arch 13. In this way, the stimulated points of the arch 13 are changed continuously, so that each of the stimulated points would not be continuously subjected to a pressing force exerted by a corresponding one of the stimulating elements 3 for a long time and the effect and comfort of massage to the muscle of the arch 13 can be improved.
