"instep" の定義と意味

What is "instep"?

The instep is the arched area on the top surface of the foot, spanning from the base of the toes to the ankle. It is characterized by a curved shape and is formed by the tarsal and metatarsal bones, tendons, ligaments, and muscles. The instep provides structural support, stability, and flexibility to the foot. It plays a crucial role in weight distribution, shock absorption, and propulsion during activities such as walking, running, and jumping. Understanding the anatomy and function of the instep is important for maintaining proper foot alignment, preventing injuries, and ensuring optimal foot mechanics.
