Background Art
[2] Generally, shocks, which are generated when walking and running with shoes on, are transmitted to all of the ankles, knees, thighs, and waist of a human body through the heels, soles and toes of the feet.
[3] Accordingly, if such shocks are transmitted to the joints of a human body for a long time, the joints are damaged, so that health may suffer. For this reason, the midsole and outsole of a shoe are formed using material having a cushioning function.
[4] However, the cushioning material, which is used for the midsole and the outsole, absorbs only a portion of the shocks, attributable to loading, which are generated when a person who wears shoes moves, and allows the remainder of the shocks to be transmitted to the human body, so that there are problems in that joints are damaged and in that fatigue is experienced.

Best Mode for Carrying Out the Invention
[19] The present invention provides a shock absorbing pad for shoes, the shock absorbing pad being mounted to shoes so as to absorb and reduce shocks applied to the heels and soles of the feet when walking or running, wherein: the shock absorbing pad is formed of a leaf spring which is bent to have a 'D' shape, the leaf spring being configured such that a plurality of through-holes is formed in each of upper and lower bent parts thereof in order to minimize the weight thereof, and coupling holes are formed both in the upper bent part and in the lower bent part, so as to be fastened to the outsole of a shoe or between the outsole and the heel of the shoe, thus being fastened to an outsole or between the outsole and a heel, or being inserted into a mounting depression which is formed in the outsole.
[20] That is, a D-shaped leaf spring is fastened to an outsole or between the outsole and a heel, or is inserted into a mounting depression, which is formed in the outsole, thus absorbing and reducing shocks applied to the heels and soles of the feet when walking or running.
[21] As shown in FIG. 1, in the shock absorbing pad for shoes according to the present invention, a leaf spring 10, which is bent into a 'D' shape, is mounted so as to absorb and reduce shocks applied to heels and soles of feet when walking or running. The leaf spring 10 is configured such that a plurality of through-holes 11 is formed in each of upper and lower bent parts 10a, 10b and 10c thereof in order to minimize the weight thereof, and coupling holes 12 are formed both in the upper bent part 10a and in the lower bent part 10c so as to be fastened to the outsole 2 of a shoe or between the outsole 2 and the heel 3 of the shoe, thus being fastened to the lower surface of the outsole 2 or between the outsole 2 and the heel 3, or being inserted into a mounting depression 4, which is formed in the outsole 2.
[22] The shock absorbing pad according to the present invention, which is constructed as described above, is mounted to shoes in order to absorb and reduce shocks applied to the heels and soles of the feet when walking or running while wearing the shoes, and is implemented in such a way that the leaf spring 10 is exposed to the outside and is fastened to the lower surface of the outsole 2, or between the outsole 2 and the heel 3, using fastening bolts 13, and is contained in the mounting depression 4, which is formed in the front portion of the outsole 2 or the heel.
[23] Respective embodiments, which are implemented in such a way that the leaf spring
10 is fastened to the lower surface of the front portion of the outsole 2, or between the outsole 2 and the heel 3, using the fastening bolts 13, so as to be exposed to the outside, are shown in FIG. 2 and 3. As shown in FIG. 2a, in the embodiment in which the leaf spring is mounted to the lower surface of the front portion of the outsole 2, the D -shaped leaf spring 10 is located under the lower surface of the front portion of the outsole 2, and then the fastening bolts 13 are fitted into the coupling holes 12, which are formed in the upper part 10a of the leaf spring 10, through the inside of each shoe, by which the installation of the leaf spring 10 to the front portion can be achieved. In this case, when a pad 5 is mounted in the shoe, through which the fastening bolts 13 are fitted in order to fasten the leaf spring 10, stimulation of the sole of the foot by the fastening bolts 13 can be prevented. Furthermore, as shown in FIG. 3, in the embodiment in which the leaf spring 10 is mounted between the outsole 2 and the heel 3, the D -shaped leaf spring 10 is located between the lower surface of the outsole 2, corresponding to the heel of the shoe, and the upper surface of the heel 3, and then the fastening bolts 13 are fitted into the coupling holes 12, which are formed in the upper and lower parts 10a and 10c of the leaf spring 10, through the inside of the shoe and through the upper surface of the lower part 10c of the leaf spring 10 located on the upper surface of the heel 3, by which the installation of the leaf spring 10 between the outsole 2 and the heel 3 can be achieved. Accordingly, shocks, which are generated when shoes come into contact with the ground, such as when walking or running, can
be absorbed, and thus damage to joints can be prevented.
[24] In this case, when a coupling depression (not shown) is formed in the lower surface of the outsole 2 or the upper surface of the heel 3, to which the leaf spring 10 is coupled, so as to hold the leaf spring 10, the coupling can be easily realized and a neat coupling can also be achieved because the coupling surface is closed after the leaf spring 10 is fastened thereto.
[25] Furthermore, as shown in FIG. 4 and 5, in the embodiment in which the leaf spring
10 is contained in the mounting depression 4 formed in the front portion of the outsole 2 or the heel, the mounting depression 4 is formed to a predetermined depth in the front portion of the outsole 2 of each shoe, or is formed in the upper surface of the outsole 2, which comes into contact with the bottom of the heel, the leaf spring 10 is inserted into the mounting depression 4, and then the fastening bolts 13 are fitted into the coupling holes 12, which are formed in the upper part of the leaf spring 10, through the inside of the shoe, so that the leaf spring 10 is securely fastened in the mounting depression 4, which is formed in the front portion of the outsole 2 of the shoe, and thus the installation of the leaf spring 10 in the mounting depression 4, which is formed in the front portion of the outsole 2 of the shoe or in the outsole 2, corresponding to the heel, can be achieved. Accordingly, shocks, which are generated when shoes come into contact with the ground, such as when walking or running, can be absorbed, and thus damage to joints can be prevented.
[26] In this case, the front portion of the outsole 2 of the shoe, in the upper surface of which the mounting depression 4 is formed to a predetermined depth, is formed to have a high thickness so that the mounting depression 4, in which the leaf spring 10 is contained, can be formed to have a predetermined depth. In this case, the increase in the thickness of the outsole 2 may cause an increase in the weight of the shoe may be increased. For this reason, space parts 2' are formed around the mounting depression 4 in the outsole 2 to reduce the weight thereof.
