What are the dangers of wearing sports shoes for a long time?

　　Sports shoes cannot ensure that the body's center of gravity is evenly distributed over the entire foot, and cannot maintain the normal position and working condition of the body's muscles, ligaments, bones and spine. After teenagers put on sports shoes or travel shoes, the body's gravity changes and the force on the feet appears unevenly distributed, which will affect the gait. Being in this bad environment for a long time will affect the physical development of teenagers.

　　Sports shoes and travel shoes have flat soles, high plasticity and elasticity, and play a certain buffering role for teenagers to run and jump. Therefore, many teenagers like to wear them. However, wearing them for a long time has many disadvantages: due to the increase in temperature and humidity inside the shoes, the sole ligaments of teenagers' feet are easy to become loose and elongated, and the soles of their feet gradually become wider, turning into flat feet over time.

　　Travel shoes are mostly made of rubber, plastic, sponge, nylon, canvas, etc., which have poor breathability. Keeping sweaty feet in this "closed" environment for a long time can easily cause fungi to multiply and spread, leading to the occurrence of athlete's foot, dermatitis, eczema wait skin disease。
