Description

Footwear articles containing highly elastic interior materials {FOOTWEAR HAVING HIGH ELASTIC INTERIOR MATERIAL}

The present invention relates to a shoe article in which the athletic function of a soccer shoe or sneaker is reinforced by adding a highly elastic interior material to the first half of the upper.

Shoes started out as a way to protect the feet, but as related technology develops, they serve a variety of purposes and functions. For example, unlike in the past when people used to do a variety of exercises with a pair of sneakers, these days, specialized shoes are available for various purposes, such as walking, running, hiking, soccer, tennis, baseball, and golf, depending on the user's needs. Functional shoes are being developed.

Generally, shoes largely include an upper part that protects the instep and joint area, and a sole part that protects the sole. The sole part is attached to the midsole and the bottom of the midsole to absorb shock. It may include an outsole for wear resistance and slip prevention. Recently, there are cases where the midsole and outsole are combined into one material and provided as one without separate separation.

Korean Patent Publication No. 10-2016-0124606 relates to “outdoor safety sandals,” and features a leisure sandal with a well-ventilated toe protector integrated into it. Korean Patent No. 10-1474896 relates to “safety shoes with a protective cover,” and is characterized by attaching the protective cover to the front of the outer surface of the upper.

Although the above-mentioned toe protectors and protective covers are suitable for protecting the toes, they have the disadvantage of stiffening the front part of the shoe and making it difficult to use them for exercise purposes.

The present invention is a shoe product that can protect the toe area like a protective cover for safety shoes, and is also suitable for active sports such as soccer, and can improve kick efficiency in soccer or other sports using the feet. provides.

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, a shoe article including a sole portion and an upper includes a base portion and a base provided along the lower portion of the upper along the boundary between the upper and the sole portion. It includes a highly elastic interior material including a plurality of protective ribs that extend upward from the upper part and cover the instep, and the high elastic interior material provides elasticity to the upper portion to protect the user's instep and increase kick efficiency in soccer or ball games. You can.

The shoe product according to this embodiment can assist the user's athletic ability for purposes such as soccer, rugby, foot volleyball, and student sports shoes, does not interfere with the bending or flexibility of the shoe, and protects the user from injuries that may occur during exercise. You can safely protect your feet.

The highly elastic interior material may be laminated on the inside or inner surface of the upper and formed integrally with the upper, and the base portion may be fixed to the sole portion together with the upper through sewing or the like.

The highly elastic interior material may be provided in various designs. For example, the protective ribs may be provided separately in a rib structure, but may be provided partially connected at the top.

High-elasticity interior materials within one upper can be provided by being connected as one, but they can also be separated into left and right sides and formed of the same or different designs or materials.

Including the highly elastic interior material of the present invention, it can assist the user's athletic ability for purposes such as soccer, rugby, foot volleyball, and student sports shoes. In existing safety shoes, the protective cover was provided in the form of an integrated cap, so not only was it unable to provide bending or flexibility, but it was also difficult to provide repulsive force in a collision with a soccer ball. However, in the highly elastic interior material of the present invention, a plurality of protective ribs extend from the base in a rib shape, so that they do not interfere with the bending or flexibility of the shoe and can improve the user's kicking efficiency.

In addition, even if the purpose is exercise, the user's feet can be safely protected from injuries that may occur during exercise, and the toes can be safely protected to some extent even if a heavy object falls on the instep or a load is applied.
