Description

TECHNICAL FIELD

[0001] The utility model relates to a shoe heel technical field, concretely relates to a shoe heel structure and fast wear formula shoes. BACKGROUND

[0002] Because the ordinary style shoes are soft, the user usually first inserts the front half of the sole into the shoe cavity from the shoe opening when wearing shoes, then lifts and pulls the shoe heel, and makes the rear root part lift to let the heel pass to complete the wearing of shoes.

[0003] In order to more conveniently and quickly wear shoes, and to avoid the action of lifting and pulling the shoe heel, the prior art makes the following improvements: one, a hard or tough support body is arranged at the shoe heel, the support body is used to provide support for the shoe heel, deformation of the heel when being pressed into the shoe cavity is avoided, and an arc extension part for guiding the heel into the shoe cavity is arranged on one side of the support body at the shoe opening, so that the wearing of shoes is completed without lifting the shoe heel.

[0004] On this basis, because of the uncomfortable feeling of knocking against the hard support member when the heel is pressed into the shoe cavity, the following improvements are made in the market: two, the support body is made of elastic material, the elastic support body is compressed and deformed to give way when the heel is pressed down, and the elastic support body restores to the vertical upward shape after the heel enters the shoe cavity. Three, a filler such as sponge is arranged on one side of the end face of the support body facing the shoe cavity to form a soft pad layer, and the comfort of the heel contacting the support body is improved. Four, on the basis of three, the filler is arranged as a strip-shaped protrusion on one side facing the shoe opening, the strip-shaped protrusion is horizontally extended corresponding to the curvature adjacent to the ankle of the heel, so that the strip-shaped protrusion fills the recessed curvature adjacent to the ankle of the heel after the heel enters the shoe cavity.

[0005] The prior art has the following problems: example one, the hard support member is simply arranged, and the wearing comfort is insufficient, and the extension structure of the arc extension part is easy to cause foreign matter to enter the shoe cavity. Example two, the elastic support body is repeatedly compressed and expanded during wearing, and the elastic structure of the support body is easy to decay and fail, which causes the wearing process to be not smooth and the heel to be easily retained, resulting in manual adjustment by the user. Example three and example four, the soft and hard combination is relatively stable, but the filler is arranged on one side of the hard support body facing the shoe cavity and the shoe opening, and the filler can only give way to one side of the hard support body when being pressed by the heel entering the shoe cavity. The travel of the thin filler is limited, which reduces the comfort, and the volume of the thick filler occupies the space in the shoe cavity, causing discomfort of the foot being pressed in the shoe cavity. In example four, the filler is arranged at the ankle, which reduces the occupation of the space in the shoe cavity, but the height of the ankle of each user is different, and the strip-shaped filler is always pressed against the ankle between the heel and the ankle, which causes discomfort to the user, and the height of the strip-shaped filler needs to be changed according to the change of the shoe size, so that the user can choose the appropriate shoes, which is obviously inefficient.

[0006] Therefore, it is necessary to overcome the above-mentioned shortcomings, provide a user with a heel structure which can quickly complete the wearing of shoes, a comfortable wearing process, and a generally applicable user's foot structure, and a reasonable application in shoe products.
