- acupuncture points of the foot F can also be stimulated to effectively improve blood circulation.
- the novel sole structure of the invention can mainly give the foot F different position stimulations every time the user steps out.
- the center of gravity will be shifted from the heel to the front of the foot, when the user is walking.
- the sole structure is given stress at different positions, and when the elastic pieces 30 , 80 of the sole structure elastically restore shape, the rebounding force can give the foot F considerable stimulation, and then massage the feet and relieve stress.

The wavy shape of theelastic piece 80 matches with the shape of thesurface 70A of therigid layer 70 such that theelastic piece 80 has a plurality ofprojections 81 and recesses 82 connected one another in sequence. Theprojections 81 and therecesses 82 are arranged at intervals, and the curves of theprojections 81 and therecesses 82 are arc-shaped, so that the appearance of theelastic piece 80 is continuously wavy. For example, twoadjacent projections 81 are connected by one of therecesses 82, and twoadjacent recesses 82 are connected one of theprojections 81. Theelastic piece 80 includes atop surface 80A and abottom surface 80B opposite to each other.

Thefront end 85 corresponds to the position of the user's toes, and therear end 86 corresponds to the position of the user's heel. An extending direction between thefront end 85 and therear end 86 is a longitudinal direction X. Theelastic piece 80 includes aninner side 87 and anouter side 88 opposite to each other. Theinner side 87 corresponds to the inner side of the foot, theouter side 88 corresponds to the outer side of the foot, theinner side 87 is closer to the other shoe body U than theouter side 88, an extending direction between theinner side 87 and theouter side 88 is a transverse direction Y, and the transverse direction Y is perpendicular to the longitudinal direction X. A length of theelastic piece 80 in the longitudinal direction X is greater than that of theelastic piece 80 in the transverse Y, theprojections 81 and therecesses 82 of theelastic piece 80 are arranged in sequence along the longitudinal direction X, and theprojections 81 and therecesses 82 extend along the transverse direction Y. - In a preferred embodiment, please refer to
FIGS. 6A and 6B , the distances betweenadjacent projections 81 are different, it is defined that theelastic piece 80 includes aforefoot section 80F and aheel section 80R. Theforefoot section 80F is closer to thefront end 85 than theheel section 80R, theheel section 80R is closer to therear end 86 than theforefoot section 80F, and an arch section 8M is connected between theforefoot section 80F and theheel section 80R.

However, the first distance D1, the second distance D2, and the third distance D3 can be changed according to user's needs. For example, when theelastic piece 80 is provided to relieve plantar fasciitis, the third distance D3 will be smaller than the first distance D1 and the second distance D2, which further makes the density of theprojections 81 in thearch section 80M higher than the density of theprojections 81 in theheel section 80R and theforefoot section 80F. - In a preferred embodiment, please refer to
FIGS. 7A and 7B , therespective projections 81 and therecesses 82 are arranged in sequence along the longitudinal direction X, and extend along the transverse direction Y, each of theprojections 81 includes ahorizontal groove 811, and thehorizontal groove 811 extends along the transverse direction Y, so that each of theprojections 81 forms twosub-projections 812, and the twosub-projections 812 are located at two opposite sides of thehorizontal groove 811, and the twosub-projections 812 can provide a better massage effect. - In a preferred embodiment, referring to
FIGS. 8A and 8B , a width of each of theprojections 81 of theelastic piece 80 along the longitudinal direction X is a first width L1, a width of each of therecesses 82 of theelastic piece 80 along the longitudinal direction X is a second width L2, the first width L1 gradually decreases from theinner side 87 to theouter side 88, and the second width L2 gradually increases from theinner side 87 to theouter side 88. The first width L1 on theinner side 87 of theelastic piece 80 is larger than the second width L2, and the first width L1 on theouter side 88 of theelastic piece 80 is smaller than the second width L2. As a result, the inner side of the user's foot can be stimulated. - The
soft layer 90 is disposed in theaccommodating space 83 of theelastic piece 80 and located between twoadjacent projections 81, and thesoft layer 90 does not fully covers theprojections 81, such that theelastic piece 80 is located between thesoft layer 90 and therigid layer 70. Theprojections 81 can directly abut against the sole of the user's foot. The material of thesoft layer 90 is softer than the material of therigid layer 70. Thesoft layer 90 can be made of materials such as ethylene-vinyl acetate copolymer (EVA), chemically crosslinked polyethylene foaming material (XPE), expandable polyethylene (EPE Expandable Polyethylene), and polyvinyl chloride (PVC). - A preferred embodiment can further include an insole layer A attached to another surface of the
elastic piece 80. The insole layer A covers theelastic piece 80 and thesoft layer 90, theprojections 81 directly abut against the insole layer A, so that theprojections 81 stimulate the sole of the user' foot through the insole layer A. - Therefore, in this embodiment, the
soft layer 90 is only disposed in theaccommodating space 83, but does not completely cover theprojections 81, so that theprojections 81 can directly abut against the sole of the user's foot or contact the insole layer A to greatly enhance the effect of stimulating ligaments and muscles. - In another embodiment, please refer to
FIG. 5 , theprojections 81 and therecesses 82 are arranged in sequence along the transverse direction Y, and extend along the longitudinal direction X. Two ends of each of theprojections 81 and therecesses 82 respectively extend to thefront end 85 and therear end 86. Similarly, theconvex portions 71 and theconcave portions 72 of therigid layer 70 are also arranged along the transverse direction Y in sequence, so that different positions of the sole of the foot can be massaged continuously along the longitudinal direction X as the center of gravity shifts while the user is walking. In addition, the user can shift the center of gravity of the sole of the foot when standing, so that the center of gravity is transferred from the inner side of the sole to the outer side, and then from the outer side back to the inner side. In this way, the sole of the foot can be fully massaged when the user stands. - What mentioned above are the structural relations of the main components, and for the operation and function of the embodiment, reference should be made to
FIG. 1-3 . - When a user steps on the mat structure or the sole structure of the present invention, a load is provided on the
elastic pieces elastic pieces elastic pieces - In addition, although the
rigid layers soft layers rigid layers elastic pieces - It is worth mentioning that, since the shape of the
rigid layers soft layers rigid layers convex portions concave portions - In addition, the novel sole structure of the invention can mainly give the foot F different position stimulations every time the user steps out. In detail, since the center of gravity will be shifted from the heel to the front of the foot, when the user is walking. During the gravity shifting, the sole structure is given stress at different positions, and when the
elastic pieces - While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
