Sneakers, also known as athletic shoes, are typically made of a combination of materials for both performance and design. The upper part of the shoe is usually made of a lightweight, breathable material such as synthetic leather, mesh, or canvas. The sole is often made of rubber or synthetic material with specific tread patterns and designs depending on the shoe's purpose. The insole, or footbed, usually contains cushioning, such as foam or air, to improve comfort and support. For added durability, many sneakers uae also feature overlays of leather, synthetic material, or plastic to reinforce the shoe and guard against wear and tear.
