[0043] like Figure 1-3 A foam shoe is shown, comprising a foam shoe body and a shoelace 4.

[0044] For the foam shoe, specifically, the foam shoe body includes a sole 1, a back of the shoe 2 and a heel surface 3, the back of the shoe 2 covers the sole 1, and the covering position extends from the toe to the heel, the lower edge of the back of the shoe 2 is connected to the sole 1 in one piece, the heel surface 3 is arranged at the heel of the sole 1, the heel surface 3 is arranged along the edge of the heel, the lower parts of both sides of the heel surface 3 extend to the back of the shoe 2, and the lower parts of both sides of the heel surface 3 are respectively connected to the lower parts of both sides of the back of the shoe 2. There is a wearing space for the foot to be inserted between the sole 1, the back of the shoe 2 and the heel surface 3, wherein the sole 1 and the back of the shoe 2 enclose a space for accommodating the front end of the foot, and the sole 1 and the heel surface 3 enclose a space for accommodating the heel. The two ends of the shoelace 4 are rotatably connected to the two sides of the back of the shoe 2, respectively, and the connection position is the lower part of the back of the shoe 2 near the heel surface 3, and the shoelace 4 can be rotated to the outer surface of the heel surface 3. By rotating the shoelace 4, the foam shoe can be used as a slipper or a sandal.

[0045] In this embodiment, the sole 1 is used as a human body bearing structure, the back of the shoe 2 is used as a wrapping and protecting structure for the instep, and the heel surface 3 is used as a wrapping and protecting structure for the heel. When the shoelace 4 is rotated upward to the back of the shoe 2, the foam shoe can be used as a slipper. In this case, the heel surface 3 is located at the heel, and the heel surface 3 moves with the heel under the heel strap, and the foam shoe itself has a light weight, which enhances the light follow-up effect. At the same time, the heel surface 3 drives the sole 1 located at the heel to bend, thereby avoiding dragging and collision with the floor when used as a slipper, and improving the adaptability to complex road conditions; when the shoelace 4 is rotated downward to the heel surface 3, the foam shoe can be used as a sandal. In this case, the shoelace 4 can apply a force to the heel surface 3, and the shoelace 4 contacts the heel with the help of the heel surface 3, and has a larger contact area. Therefore, when walking, the heel surface 3 has a better heel following effect, the foam shoe moves with the foot, and the heel is subjected to less pressure, and it has better comfort whether it is at home, walking in the city, or wading on the beach.

[0046] Furthermore, the shape of the heel surface 3 is adapted to the shape of the heel. Specifically, the inner surface of the heel surface 3 bends with the bending of the heel, and the heel surface 3 has a good fit with the heel. On the one hand, the force on the heel is uniform, and the probability of heel friction damage is reduced. On the other hand, the heel surface 3 has a good fit with the heel, and the force applied by the heel to the heel surface 3 is uniform, which can also make the heel surface 3 more easily move with the heel.

[0047] Furthermore, if Figure 1 , Figure 3 As shown, an adjustment groove 5 is provided at the connection between the heel surface 3 and the back surface 2, which is used to reduce the pulling force of the back surface 2 on the heel surface 3. Specifically, the adjustment groove 5 extends from the connection between the heel surface 3 and the back surface 2 to the sole 1, so that the pulling force of the back surface 2 on the heel surface 3 can be reduced, the elasticity of the back surface 2 can be improved, and the convenience of wearing shoes can be improved.

[0048] In some embodiments of the shoe back 2, such as Figure 3 , Figure 4 As shown, a plurality of vents 21 are provided on the back of the shoe 2. By providing the vents 21, the ventilation effect inside the foaming shoe is improved, making the foaming shoe cooler.

[0049] In some embodiments of the sole 1, the user needs to wear foam shoes to wade in a stream, and the bottom surface of the sole 1 is provided with a plurality of anti-skid protrusions 11 for increasing friction. The anti-skid protrusions 11 increase the friction between the sole 1 and the bottom of the stream to prevent or avoid slipping.

[0050] Furthermore, if Figure 5As shown, the top surface of the sole 1 is provided with a toe anti-slip area 12, a sole anti-slip area 13, an arch massage area 14 and a heel anti-slip area 15. The sole anti-slip area 13 is located at the front of the sole, and the arch massage area 14 is provided with massage protrusions. On the top surface of the sole 1, the toe anti-slip area 12, the sole anti-slip area 13 and the heel anti-slip area 15 make the contact area between the foot and the sole 1 have greater friction, reducing or preventing the foot from slipping inside the foam shoe. In addition, the massage protrusions in the arch massage area 14 can massage the arch, thereby increasing the function of the sole 1.

[0051] In some embodiments of foam shoes, such as Figure 1 As shown, the foam shoe further includes a rotating connection assembly 6, a part of the rotating connection assembly 6 is connected to the shoe back 2, and the other part is connected to the shoelace 4, and the shoelace 4 is rotatably connected to the shoe back 2 through the rotating connection assembly 6. The shoelace 4 is rotatably connected to the shoe back 2 through the rotating connection assembly 6, so that the shoelace 4 can be manually rotated, that is, the shoelace 4 is manually rotated to the shoe back 2 or to the heel surface 3.

[0052] Specifically, if Figure 6 , Figure 7 and Figure 8 As shown, the rotating connection assembly 6 includes a first connection member 61 and a second connection member 62. The first connection member 61 includes a first connection piece 611 and a rotating shaft 612, the rotating shaft 612 is arranged on the first connection piece 611, and the rotating shaft 612 is provided with an undercut groove 6121. The second connection member 62 includes a second connection piece 621 and a rotating sleeve 622, the rotating sleeve 622 is arranged on the second connection piece 621, and the inner wall of the rotating sleeve 622 is provided with an undercut 6221. The rotating shaft 612 rotatably extends into the rotating sleeve 622, and the undercut 6221 extends into the undercut groove 6121. Specifically, the second connecting piece 621 is attached to the outer surface of the shoelace 4, the rotating sleeve 622 passes through the shoelace 4, the first connecting piece 611 is attached to the inner surface of the back of the shoe 2, the rotating shaft 612 passes through the back of the shoe 2 and extends into the rotating sleeve 622 and is rotationally connected with the rotating sleeve 622, and the undercut 6221 extends into the undercut groove 6121. In this way, the first connecting member 61 and the second connecting member 62 are rotationally connected.

[0053] Of course, the first connecting member 61 and the second connecting member 62 may also be assembled at different positions.

[0054] More specifically, if Figure 7As shown, the undercut 6221 is circumferentially arranged on the inner wall of the rotating sleeve 622. The rotating sleeve 622 is provided with a deformation slit 623 for increasing the deformation amount. The deformation slit 623 extends from the inside of the rotating sleeve 622 to the outer wall of the rotating sleeve 622, and the deformation slit 623 extends at least to the undercut 6221. By providing the deformation slit 623, the rigidity of the undercut 6221 is reduced, and the rigidity of the rotating sleeve 622 is reduced, so that when the rotating shaft 612 and the rotating sleeve 622 are assembled, the undercut 6221 and the rotating sleeve 622 can generate sufficient elasticity, which facilitates the assembly of the rotating shaft 612 and the rotating sleeve 622.

[0055] Of course, the deformation gap 623 may also extend to the rotating sleeve 622 , thereby further increasing the deformation capacity of the rotating sleeve 622 and reducing the difficulty of assembling the rotating shaft 612 and the rotating sleeve 622 .

[0056] In some embodiments of the sole 1, Fig. 9 As shown, a plurality of elastic air bags 7 are arranged in the sole 1, and air is contained in the elastic air bags 7. The elastic air bags 7 increase the elasticity of the sole 1 and improve the comfort when wearing.

[0057] Furthermore, if Fig. 9 As shown, the bottom surface of the sole 1 is provided with a plurality of anti-skid protrusions 11 for increasing friction, and the elastic airbag 7 is located above the anti-skid protrusions 11. The area where the anti-skid protrusions 11 are provided has more space for accommodating the elastic airbag 7, thereby improving the convenience of injection molding of the foam shoe.

[0058] For foam shoes, especially foam shoe bodies, EVA material is used as the main material, and modified materials are added to adjust the performance of the foam shoe body, which at least include polyolefin plastomers, olefin block copolymers, talcum powder, foaming agents, cross-linking agents, etc.

[0059] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
