What is heel spring?

Heel spring refers to the amount of cushioning and support that a shoe's heel provides. It is an important factor for individuals who engage in physical activities that involve running or jumping, such as athletes. The heel spring can help absorb shock to reduce the impact on the feet and joints, and it can also provide stability to enhance the foot's natural movement. The amount of heel spring varies depending on the type of shoe and the manufacturer, so it is important for individuals to choose a shoe that provides adequate support for their specific needs and activities.
