1.    Introduction
The foot is the most important part of the interaction between the ground and the body in humans. Its functional structure is very influential on the walking pattern (1-2). Any kind of deviation in the legs will affect the joints and higher organs respectively. Changes and displacements in the anatomical structure and bones of the foot lead to abnormal movement of the foot while walking. Therefore, the occurrence of abnormality in this part has a special importance in terms of biomechanics (2). Therefore, as a necessary and very important tool, shoes play a significant role in taking optimal steps and supporting the lower limbs. Research shows that a suitable shoe design can create a significant change in the biomechanical parameters of the foot. For this purpose, shoe manufacturers have made various changes into it. Therefore, it is necessary to pay attention to new innovations in this sector. Technology in the world is one of the most important tools for progress, injury prevention and rehabilitation of athletes. In ensuring the safety of measurement and evaluation of sports techniques and skills, and following that, raising the performance levels all around, especially in the sports competitions of athletes that are ahead, along with the development of technology and technology in the field of sports, the construction of equipment has also been taken into consideration (3). Kinematic calculations in sports are performed in different ways, of which goniometry and accelerometer are the most widely used forms, which directly calculate some important kinematic parameters of movement. Being portable, the ability to quickly transfer information to a computer and the low price of these devices are some of the advantages of this research style (5). In recent years, versions of matrix and magnetic sensors were presented, which investigated kinematic and also kinetic parameters in the measurement without imaging (6-7). The main problem of some of these similar devices is the limitation of movement in the field performance of athletes. Using sensors embedded in the body, such as shoes, and being in the field could reduce these limitations to some extent (8). It should be mentioned that the modeling of human movement and the use of devices that did not need pointers were other methods for analyzing movement, but each of them had limitations. Today, common methods for calculating movement dimensions are the use of imaging techniques and image processing algorithms and the use of different dynamometers and sensors or different forms of force plates in kinetics. Optimum accuracy, the ability to process in real time and not restricting movement for the user by pointers are among the advantages of similar devices. Therefore, the researcher decided to design and present the present shoes.
2.    Methods
In this section, the shoes and their equipment are connected to the person and are tied to the waist and feet of the device by a strong elastic band and are supported. Modules for sending and receiving information are also used during the beginning of the exercise. A person wears these shoes while doing exercises in the laboratory and especially in field conditions, and when the device is turned on, information such as location, time, acceleration, and force are entered into the researcher-made software in the computer. The trainer or researcher can also receive and analyze information at a maximum distance of 300 meters according to the module's capabilities. In fig. 1, the laboratory sample of this shoe is displayed. This design has been registered with Iran's Industrial Property Department under certificate number 74929 dated 2013/2/17 in the name of the author of the invention article.

3.    Results
Advanced C language programming software was used to draw a diagram and quantitatively present the research variables resulting from the sensors and analyze the resulting findings. This system can also prepare graphs, store and analyze data. Other suggested capabilities include producing shoes suitable for the weight of people's feet, creating plans for various sports, diagnosing diseases such as flat feet, back pain, and ways to treat them.
 4.    Conclusion
This shoe can help improve athlete's performance by quantifying qualitative information, as well as in some foot injuries.
