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 for the wearer. Made from materials like rubber or synthetic compounds, the outsole helps protect the shoe and the foot from wear and tear while walking or running. Different types of outsoles are tailored for specific activities, such as running, hiking, or basketball. For instance, a running shoe may have a lightweight outsole for speed, while a hiking boot features a rugged outsole for better grip on uneven terrain.
