[0002] Shoes can comprehensively wrap the human foot to facilitate walking and protect the foot from injury. In particular, for sports shoes or casual shoes, a heel cup is usually arranged at the heel part of the shoe. The heel cup is a hard arc-shaped cup structure that can provide stable support for the foot.

[0003] The existing heel cup is generally arranged corresponding to the calcaneus position of the human foot and has a low height. This is because the heel cup is usually made of a relatively hard material to achieve sufficient support. If the height of the heel cup is too high, on the one hand, it is easy to rub against the back of the ankle, causing discomfort or even injury. On the other hand, it is not convenient to put on and take off the shoe. In this case, a relatively thick foam structure is usually arranged at the position above the heel cup corresponding to the back of the ankle to provide certain support and protection for the ankle joint.

[0004] Therefore, the existing heel cup has a limited range of support and protection for the foot. Although the foam with a soft texture is comfortable, it has poor support and protection effect. Moreover, the thick foam structure can also press the Achilles tendon at the ankle, causing discomfort. In addition, since the foam structure protrudes above the heel cup by a certain height, the human foot will repeatedly step on the foam structure during the process of putting on and taking off the shoe, which can easily cause deformation or damage to the connection between the foam structure and the upper edge of the heel cup, ultimately affecting the wearing comfort and service life of the shoe.

[0022] In order to better understand the purpose, structure and function of the utility model, the heel cup and shoe capable of improving the comfort and easy wearing and taking off of the heel are further described in detail below in combination with the drawings.

[0023] As shown in Figure 1 and Figure 2 , the heel cup capable of improving the comfort and easy wearing and taking off of the heel of the utility model is arranged at the heel part of the shoe, comprising a support part 1 and a curved part 2 arranged integrally, wherein the support part 1 is arranged corresponding to the position of the human calcaneus, the curved part 2 is arranged at the upper part of the support part 1, the upper end of the curved part 2 is arranged extending in the vertical direction towards the direction of the human Achilles tendon, and the upper end of the curved part 2 is arranged extending in the horizontal direction towards the direction away from the human heel, so as to form an inclined surface convenient for wearing and taking off, and the hardness of the curved part 2 is less than the hardness of the support part 1.

[0024] The support part 1 arranged corresponding to the calcaneus can provide a certain supporting effect for the heel part of the human body, and at the same time, when the shoe is worn, the heel part of the human body can slide down along the inclined surface formed at the upper end of the curved part 2, so as to be convenient for wearing and taking off. The hardness of the curved part 2 is less than the hardness of the support part 1, which can make the heel cup provide sufficient supporting effect while being beneficial to the moderate deformation of the curved part 2 when the heel is stepped on, so that the foot is more easily worn into the inside of the shoe. In addition, compared with the traditional heel cup structure without the curved part 2, the curved part 2 can also provide a certain supporting effect on the foam covered outside, reduce the problem of damage and deformation of the foam part caused by repeated stepping of the heel, and prolong the wearing life of the foam structure at the heel part of the shoe. In the heel cup of the utility model, the support part 1 and the curved part 2 are arranged integrally, and are made of a double-hardness high-elastic material with soft upper and hard lower, which can adapt to the angle of the foot and the shoe opening according to the angle of the foot worn in, achieve the effect of quick wearing, and the integrity of the heel cup is better, the transition of the supporting performance and the easy wearing and taking off performance is smoother, and the wearing feeling is more comfortable.

[0025] Further, the bending part 2 is in a U-shaped structure as a whole, comprising an integral intermediate part 21, an inner extension part 22 and an outer extension part 23, the inner extension part 22 and the outer extension part 23 are respectively connected to the inner and outer sides of the intermediate part 21, the intermediate part 21 of the bending part 2 extends from the upper part of the supporting part 1 to the direction of the Achilles tendon of the human body, and the inner extension part 22 and the outer extension part 23 of the bending part 2 extend to the inner and outer sides of the supporting part 1 respectively. Since the hardness of the bending part 2 is smaller than that of the supporting part 1, the inner extension part 22 and the outer extension part 23 located at the outer edge of the supporting part 1 are also more easily deformed, and when wearing shoes, it is more convenient for the heel part of the shoe to form a large enough opening, so that the inner and outer sides of the heel can quickly and smoothly step into the shoe. At the same time, because of the transition of the bending part 2 with smaller hardness, the supporting force of the outer edge of the heel cup on the human foot will be moderately smaller, the comfort is better, and the overall supportability will not be weakened.

[0026] Further, the upper edge of the intermediate part 21 of the bending part 2 extends to the heel opening of the shoe. Compared with the existing heel cup, the bending part 2 in the heel cup of the present application is arranged at a higher position, so as to form a larger space for the foot to enter at the opening of the shoe, facilitating putting on and taking off.

[0027] Further, the height of the supporting part 1 is 50-90mm, and the height of the intermediate part 21 of the bending part 2 is 40-60mm.

[0028] Further, the lower end of the inner extension part 22 of the bending part 2 extends to the lower edge of the inner side of the supporting part 1, and the lower end of the outer extension part 23 of the bending part 2 extends to the lower edge of the outer side of the supporting part 1. Preferably, the width of the inner extension part 22 of the bending part 2 is 6-10mm, and the width of the outer extension part 23 of the bending part 2 is 6-10mm. This arrangement can more fully improve the influence of the heel cup on the comfort and easy wearing and taking off of the heel.

[0029] Further, the thickness of the supporting part 1 is 1.0-4.0mm, and the thickness of the bending part 2 is 0.6-4.0mm. The thickness of the bending part 2 is thinner at the edge part away from the supporting part 1, which can avoid the problem of rubbing feet caused by the over-thick edge of the heel cup, and the thickness of the bending part 2 is larger at the position connected with the supporting part 1, which is conducive to improving the overall supportability and wrapability of the heel cup.

[0030] Further, the hardness of the supporting part 1 is 50-60D, and the hardness of the bending part 2 is 25-30D. The softer bending part 2 can provide a larger deformation space when the foot enters, and can quickly rebound after the foot enters the shoe, while relieving and avoiding the discomfort of rubbing feet at the edge of the heel cup.

[0031] The support part 1 and the bending part 2 are made of TPEE material, have the advantages of being resistant to bending, strong toughness, durable, strong comfort and recyclable, and the density is 1.10-1.34g / cm 3 Preferably, the support part 1 and the bending part 2 are integrally formed by injection molding, and in this way, the heel cup is more integrally formed, the hardness transition between the support part 1 and the bending part 2 is more uniform, the connection strength between the support part 1 and the bending part 2 is better, and the heel cup is not easy to be damaged by bending; compared with the split setting mode, the one-time vehicle line process can be reduced, the cost can be saved, the production efficiency can be improved, and the connection position of the support part 1 and the bending part 2 will not have the problem of misalignment and poor adhesion, and the wearing and taking are more smooth.

[0032] The utility model discloses a kind of shoes, specifically including the foam structure being arranged at heel position, and the heel cup in the utility model above, heel cup is arranged inside foam structure, foam structure includes foam main body and buffer part, foam main body is set corresponding the position of human calcaneus, buffer part is set in the upper portion of foam main body, the support part 1 of heel cup is located in foam main body, the bending part 2 of heel cup is located in buffer part. Since the bending part 2 of heel cup can also replace the buffer part in foam structure and play certain support and protection effect to achilles tendon area on the upper portion of human calcaneus, compared with the existing shoe structure, the shoe in the utility model can set very light and thin foam buffer part, on the one hand, reduce the extrusion and bondage feeling of foam buffer part to heel rear, further improve the overall comfort of heel, on the other hand, thinner foam buffer part is not easy to be stepped deformation or damaged because of the support of the bending part 2 of heel cup in the process of bearing heel repeatedly stepping.

[0033] The heel cup and shoe of the utility model can improve the comfort and easy wearing and taking of heel, can adapt to the angle of foot and shoe opening according to the wearing angle of human foot, achieve the effect of quickly wearing, compared with the design of single density, large hardness and unable to freely bend of traditional heel cup, the heel cup in the utility model not only can make shoe more convenient to wear and take, but also can greatly improve the wearing comfort of heel part, and make heel part not easy to be deformed or damaged due to repeatedly stepping, prolong the wearing life of shoe.
