The present invention relates to a soccer shooting training apparatus, and more particularly, to a soccer shooting training apparatus in the form of socks or soccer shoes.

Conventional soccer shooting practice has been relied on personal sense or posture has been corrected by a coach's subjective observation.

In other words, since soccer shooting is made by an instantaneous motion, it is difficult to precisely observe the position between the stepping foot and the shooting foot and which part of the shooting foot the soccer ball hits during shooting. It is true that it has been

As described above, when shooting soccer, the shooting posture of the trainee according to the position of the hitting point and the position of the step and shooting foot is not immediately confirmed, so the training effect may be absent or appear very different depending on individual sensory differences.

That is, there is a problem in that the shooting posture cannot be corrected and the training effect cannot be objectively confirmed through conventional shooting practice.

Referring to FIG. 1 , in Patent Document 1, a sensor system 1212 includes a sensor assembly 1213 connected to an upper 120 of an article of a shoe 100 , and the sensors 1216 are woven into the material of the shoe upper. These may be FSR sensors, the upper may also be woven with conductive fabrics to form the leads 1218 , the electronic module 22 is incorporated into the sole 130 of the shoe 100 , and the leads 1218 . Footwear is described having a sensor system that extends from the silver upper 120 down the foot contact member 133 to a port 14 in communication with the module 22 .

However, the sensors for detecting the soccer shooting site should be replaced frequently because the durability is considerably reduced by the impact whenever the soccer ball hits the shooting foot, but the sensor system of Patent Document 1 has the sensors 1216 Since the upper is woven inside, there is a problem that it cannot be replaced.

In addition, since Patent Document 1 has a structure in which a plurality of sensors are installed in a desired portion of the upper, there is a problem in that the load distribution applied to the surface of the shooting foot cannot be grasped during shooting.

In addition, Patent Document 1 has a problem in that it is not possible to determine how far the step is from the shooting foot during shooting.
