TECHNICAL FIELD

[0001] The utility model relates to the technical field of shoes, especially to a supporting piece for shoes and a heel preventing shoe back upper. BACKGROUND

[0002] Shoe heel slipping refers to the phenomenon that the shoe heel is separated from the foot during wearing, resulting in that the shoe cannot be normally fixed on the foot and is easy to fall off. During wearing, the shoe heel slipping may be caused by the foot shape problem of the wearer, bad wearing habits, unsuitable shoe size, unreasonable shoe design, and the like. The shoe heel slipping not only affects the comfort and appearance during wearing, but also may cause adverse effects on the foot health and bring many troubles to the wearer.

[0003] Except for the personal reasons of the wearer, optimizing the shoe type and improving the back upper material are the main ways to solve the shoe heel slipping problem. In the overall shape and structure design of the shoe, the supporting piece inside the shoe and the shoe back upper are important components, which are located at the rear of the shoe and play a role in fixing the heel of the foot, and are the key positions to determine whether the shoe heel slips or not. Therefore, it is necessary to design more reasonable supporting piece and shoe back upper structure to ensure that the shoe closely fits the heel of the foot and provides good support and comfort, so as to reduce the occurrence of the heel slipping and solve the problem of the shoe heel slipping.

[0023] The utility model will be further explained in connection with the drawings and specific embodiment.

[0024] Embodiment one

[0025] As Figures 1-3 The utility model discloses a kind of supporting pieces for shoes, it is embedded in the heel of upper, including two parts structures of shoe rear lining 100 and elastic pad 200.

[0026] The cross section of shoe rear lining 100 is C type, including integrally formed two wing pieces 120 and a rear lining piece 110, the position of two wing pieces 120 corresponds to the inside and outside of the heel of foot respectively, and the upper edge of two wing pieces 120 is all inward, i.e. inwardly set towards the direction of shoe opening, rear lining piece 110 is located at the rear side of the heel of foot, and rear lining piece 110 has recess 111 matched with the heel of foot. By the cooperation of rear lining piece 110 and two wing pieces 120, hard and powerful support can be provided to the heel of upper, to maintain the three-dimensional shape of the heel of upper, and cooperate with the heel of upper to limit the heel of foot in a relatively stable position, prevent the foot from slipping out during walking or movement, improve the phenomenon of heel drop.

[0027] In longitudinal direction, the thickness of shoe rear lining 100 is gradually reduced at least from middle part to upper part, and the thickness range is 0.8-4.0mm. The design of gradually reducing thickness makes shoe rear lining 100 support and fix the heel of foot, without excessively limiting the heel of foot to affect ankle movement flexibility, to ensure that ankle movement is more free.

[0028] Elastic pad 200 is made of foam material, and at least a part thereof is located in the upper inner side of rear lining piece 110 and extends towards the inner side of rear lining piece 110, and the surface of elastic pad 200 can be matched with the heel of foot. By elastic pad 200, additional elastic support can be provided, and the wrapping property of the heel of upper is enhanced, to assist the heel of foot to maintain correct position and posture, and further reduce the occurrence of heel drop phenomenon.

[0029] More specifically, in the longitudinal direction, the upper thickness T1 of the rear shoe pad 100 is 0.8-1.8mm, the middle thickness T2 and the lower thickness T3 of the rear shoe pad 100 are 2-4mm, and the height of the entire rear pad 110 covers about two-thirds of the area of the heel of the foot, i.e. from the bottom of the heel of the foot to the area where the Achilles tendon begins, usually about 3-5cm.

[0030] In one case, in the longitudinal direction, the thickness of the rear shoe pad 100 gradually decreases from the bottom to the upper part. For example, the maximum lower thickness T3 of the rear shoe pad 100 can be set to 3mm, and the overall thickness of the rear shoe pad 100 gradually decreases from 3mm to the minimum upper thickness T1 of 1.5mm. The gradual decrease in the overall thickness can effectively avoid the feeling of strangeness caused by the change in thickness, improve the comfort of wearing, reduce stress concentration, reduce the risk of material fatigue and damage, and prolong the service life of the shoe.

[0031] In another case, in the longitudinal direction, the thickness of the rear shoe pad 100 is uniform from the bottom to the middle, and the thickness gradually decreases from the middle to the top. For example, the lower thickness T3 of the rear shoe pad 100 can be kept at 3mm, the middle thickness T2 of the rear shoe pad 100 gradually decreases from 3mm to 2mm, and the upper thickness T1 of the rear shoe pad 100 gradually decreases from 2mm to 1.5mm. By keeping the lower thickness T3 of the rear shoe pad 100 uniform, which is less likely to be perceived by the heel of the foot, the strength of the rear shoe pad 100 can be enhanced, and the supporting effect of the rear shoe pad 100 can be improved while avoiding the feeling of strangeness.

[0032] In terms of curvature, the rear pad 110 is formed by a plurality of smoothly connected curved surfaces from the upper part to the lower part, the curvature centers of the middle curved surface and the lower curved surface are arranged inside the rear pad 110 to form a concave part 111, and the curvature center of the upper curved surface of the rear pad 110 is arranged outside the rear pad 110. More specifically, the transverse distance L1 between the part of the inner side of the rear pad 110 covered by the elastic pad 200 and the heel of the foot gradually decreases from top to bottom. Correspondingly, in the same horizontal plane, the transverse distance L2 between the surface of the elastic pad 200 and the inner side of the rear pad 110 is greater than the transverse distance L1. That is, according to the thickness of the elastic pad 200, the curvature of the upper part of the rear shoe pad 100 is adjusted accordingly, rather than being uniformly set according to the specifications, which can make the elastic pad 200 more fit the heel of the foot, appropriately press the heel of the foot, and thus enhance the anti-slip effect.

[0033] As a preferred embodiment, when the transverse distance L2 is 10mm, the transverse distance L1 is set to 5-7mm; when the transverse distance L2 is 12mm, the transverse distance L1 is set to 6-8mm; and when the transverse distance L2 is 15mm, the transverse distance L1 is set to 7-11mm.

[0034] Embodiment Two

[0035] On the basis of the above embodiment one, as Figure 4 The utility model discloses still disclose a kind of shoe backstay of preventing heel drop, including surface layer 300, inner layer 400 and the shoe support piece described above, surface layer 300 and inner layer 400 are mutually connected and form interlayer space 500 between them, shoe backer 100 is supported in interlayer space 500, and elastic pad 200 is filled in the upper portion of interlayer space 500.

[0036] Wherein, surface layer 300 is appearance layer, inner layer 400 directly contacts foot skin.Shoe backer 100 plays rigid support role, can fix shoe backstay shape, make it keep good appearance and line, help to fix foot heel, assist foot to keep correct position and posture, avoid heel drop.Elastic pad 200 plays elastic support role, can further enhance the wrapping property of shoe backstay, fill the gap between ankle and shoe backstay, so that ankle keeps relatively fixed position in shoe, prevent ankle from excessive shaking or displacement during movement and lead to injury.

[0037] Although the utility model is specifically shown and introduced in combination with preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all such changes are within the protection scope of the utility model.
