1.    Introduction
Sports biomechanics is a scientific field that provides quantitative and sometimes qualitative evaluations of sports performance (1). Measuring and specifying human movements during sports activities is one of the vital aspects for athletes today and an important program for coaches to improve techniques and prevent sports injuries (2). Advances in technology in various fields pave the way for a growing future, including smart applications, wearable technologies, and the Internet of Things, which enable comprehensive integration into people's lives (3). By exploring the effects of smart technologies on sports equipment development, materials engineering for sports equipment has led to many advances in the sports industry, such as the use of lightweight materials with high resistance and unique designs and features (4, 5). Accordingly, Nobakht et al. (2023) conducted research to design and manufacture various sports shoes using nano silver to prevent germs and viruses. The results showed that the use of nano silver in designing and manufacturing various sports shoes can be useful in preventing and controlling many microbes and viruses (7).
2.    Methods
According to the subject and objectives of the research, an applied research method was used in this study. First, electronic components such as Arduino Nano board, nanopower supply, force-sensitive sensor, jumper wire, 10-ohm resistor, MicroPython chip, electronic printed board, system parasite trap, Wi-Fi module, and a pair of sports shoes were prepared to place the parts inside. After preparing the electronic parts, the control board was first checked with a JTAG test to ensure that there was no interference or disturbance on the parts. In the second step, all sensors and the microcontroller board were designed and simulated using Altium Designer software, as shown in Fig. 1.

Next, we wired and soldered the electronic board. After finishing the soldering, we designed the system's power supply and connected it to the control chip. In the next step, which was the most important part of the work, we installed the MicroPython software on the programming system. By connecting the control board with the network cable, we first tested the sensors and started writing the programming, which is the programming language used in this project. After writing the programming process, we coded the written codes for the Android operating system, then sent the sensor information to the Wi-Fi module and coded the network address for these sensors. After this step, the control board designed and coded using Android software was designed for these sensors, and the information of the sensors was displayed in the application.
3.    Results
Considering that each sport has its own exercises and a unique order, the athletes will be able to identify and control the forces entering their lower body during various sports activities with the design of smart sports shoes.
4.    Conclusion
The use of new smart sports shoes to measure ground reaction forces and display them online during various sports activities can be beneficial.
