Description

Technical Field

[0001] The utility model belongs to the field of shoes, and in particular relates to a strong and tough shoe midsole formed of a foaming material. Background Art

[0002] The construction of a shoe sole is quite complex. Broadly speaking, it encompasses all materials that make up the outsole, midsole, and heel. In a narrower sense, referring only to the outsole, common sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, elastic, easily adaptable to the foot shape, durable once shaped, heat-insulating, and moisture-absorbent. Furthermore, they must complement the midsole to provide a braking effect when changing feet while walking, preventing slipping and making it easy to stop. There are many different types of sole materials, which can be categorized as natural or synthetic. Natural sole materials include natural leather, bamboo, and wood, while synthetic sole materials include rubber, plastic, rubber-plastic composites, recycled leather, and resilient cardboard.

[0003] However, the overall strength and toughness of the tough shoe midsole in the prior art are relatively poor, and the thickness of the sole is relatively thin, which is not only uncomfortable to wear, but also puts the wearer at risk of sprains and falls. Utility Model Content

[0004] The embodiment of the utility model provides a strong and tough shoe midsole formed of a foam material to solve the problems in the prior art.

[0005] The embodiment of the present utility model adopts the following technical solution: a strong and tough shoe midsole formed of a foam material, including a shoe midsole main body made of foam material; the shoe midsole main body is composed of four parts: a first area, a second area, a third area and a fourth area; the space formed by the four parts can fully wrap the wearer's sole; the overall configuration of the shoe midsole main body forms a first slope from the heel to the middle of the foot, and a second slope from the middle of the foot to the toe; the first slope and the second slope are configured to fully fit the sole of the wearer's foot.

[0006] The midsole body of the medium-strength and toughness shoe of the utility model is made of foam material. At the same time, the thickness of the connecting part between the midsole and the upper is thicker than that of other parts, which not only makes the shoe comfortable to wear but also more elastic.

[0007] A further technical solution is that the first area has a first accommodating groove and a fourth accommodating groove; the second area is located on the outside of the first area, and has a bent and extended bridge portion; a fifth accommodating groove and a sixth accommodating groove are provided on the second area on one side of the bridge portion; the fifth accommodating groove and the sixth accommodating groove are connected with the fourth accommodating groove.

[0008] A further technical solution is that the third area and the fourth area are located at the bottom of the first area; a first protrusion is provided at the bottom of the third area; a second accommodating groove is also provided in the third area; a protrusion block is provided on the first protrusion; a plurality of protrusions are provided on the side wall of the first protrusion; and a plurality of recesses are provided on the side wall of the second accommodating groove.

[0009] According to a further technical solution, a first groove matching the first protrusion is provided at the bottom of the fourth zone; a second protrusion matching the second accommodating groove is provided at the fourth zone; a plurality of protrusions are provided on the side wall of the first groove; and a plurality of depressions are provided on the side wall of the second protrusion.

[0010] According to a further technical solution, the first slope is slowly downward and the second slope is upward.

[0011] According to a further technical solution, the thickness of the shoe midsole body is 3 mm to 32 mm.

[0012] According to a further technical solution, the middle thickness of the portion where the midsole body is connected to the upper is 70% to 90% of the thickness of the midsole body.

[0013] According to a further technical solution, the middle thickness of the portion where the midsole body is connected to the heel is 50% to 70% of the thickness of the midsole body.

[0014] At least one of the above technical solutions adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0015] The utility model can solve the shortcomings of the existing technology and increase the overall strength and toughness of the shoe midsole. The strong and tough shoe midsole body is made of foam material. At the same time, the thickness of the connecting part of the shoe midsole and the upper is greater than the thickness of other parts, which not only makes the wearer comfortable and more elastic, but also makes walking lighter and faster. At the same time, by making the thickness of the part connected to the upper and the heel 70% to 90% of the thickness of the entire shoe midsole body, the wearer's walking safety is effectively improved, and the probability of sprains, falls, etc. of the wearer is greatly reduced.
