Problems solved by technology

When the heel wears out due to repeated use, a person's walking posture might look uneasy.

In the event that a person walks for a long time wearing the shoes whose heels are severely worn out, a user body might look like a pigeon-toed walking posture or might look bad with an 0-shape formed between two legs depending on the degree that a heel inwardly or outwardly wears out.

In this case, it is impossible to exchange only the heels for reuse.

Even though the upper sides of the sneakers are not fully damaged or worn out, it is needed to exchange the sneakers, which results in economic losses.

In the event that the heels are repaired in such a way to exchange the heels at a shoe repair shop like the preceding shoes, it is needed to search for a skilled shoe repairman which produces lots of uneasiness and inconveniences, and repair costs and time increase.

The outer sides of the repaired shoes might look unclean, thus making the outer sides of the shoes look bad.

The heels are fixed as the securing protrusions are secured to the securing holes, so the fixed force is weak, thus causing the heels to disengage which might bring in a critical problem during the use of products, whereby a product quality and a product reliability of shoes are largely damaged.

The shoe heel apparatus of another preceding application of Korean utility model application number 85-632 comprises a reinforcing plate and a plurality of securing elements such as bolts and nuts, which makes the structure complicated and the manufacture process and unit cost increase.

Since a certain tool is additionally used during the exchange of heels, an easiness and convenience of exchange are bad, which drives a product purchase desire to drop.

As the interconnected securing elements might be loosened during the wearing of shoes, the heels might escape owing to loosening.
