Running shoes and walking shoes differ primarily in their design and purpose. Running shoes are built for forward motion with features like cushioning to absorb impact, stability to support the foot during quick movements, and flexibility for swift transitions. They are lightweight and often have breathable mesh uppers to keep feet cool.

On the other hand, walking shoes prioritize comfort and support for prolonged walking. They typically have more cushioning in the heel and forefront to enhance comfort over longer distances. Walking shoes also focus on stability but with less emphasis on flexibility, as they are designed for a consistent, steady stride rather than rapid changes in movement.
