Advantages of comparison between orthopedic shoes and orthotics: Traditional orthotics are generally made of polypropylene plastic, which has high strength and hardness. When in use, it directly touches the patient’s foot and is easy to cause damage to the patient’s foot. Wear and tear, and its higher hardness, tends to fix the ankle and foot extensively. For mild patients, it will cause excessive fixation and loss of necessary freedom of movement. Orthotics are generally large and need to be worn. After reaching the foot, coat wider shoes, so that the patient wears big shoes on small feet, causing poor gait, and at the same time, the orthosis is exposed, which affects the appearance.
