Which type of shoe is generally heavier and provides more stability during athletic activity?

Weighted shoes are designed specifically to add extra mass, which can enhance stability during athletic activities. The added weight helps in developing strength and endurance in the muscles of the horse's legs. This type of shoe is often used during training sessions to prepare the horse for competition, as the increased weight can improve their performance when they transition to lighter shoes.

In contrast, the other choices primarily focus on either being lightweight or less stable. For instance, plastic shoes are lighter and more flexible, which helps with traction but doesn’t provide the same level of stability. Steel shoes, while heavier and durable, they are not specifically designed to be weighted for the purpose of stability; they often serve to protect the hooves. Light shoes, as the name suggests, are designed for speed and agility, sacrificing stability to facilitate those attributes.
