The outsole is the bottom part of a shoe that comes into direct contact with the ground. It is designed to provide traction, durability, and support. Outsoles can be made from various materials, including rubber, leather, or synthetic compounds, depending on the shoe's intended use, such as for running, hiking, or casual wear. The design of an outsole can vary significantly, featuring different patterns and treads to enhance grip and stability. For example, athletic shoes often have specialized outsoles to improve performance on specific surfaces, while dress shoes may have smoother outsoles for a more polished appearance.
