Midsole is a term used to describe the cushioning and support found in the middle of a sneaker. This layer is between the upper and the outsole of the sneaker, and is designed to provide cushioning and support for the wearer’s feet. Midsole materials can vary greatly, from foam to air-sole, and can have a big effect on the comfort and performance of a sneaker.
The midsole is an important aspect of a sneaker's design as it can affect the overall performance and comfort of the shoe. Different types of midsole materials offer varying levels of support, cushioning, and durability. For example, EVA foam is a popular choice for midsoles as it is lightweight, durable, and provides good cushioning. Air-sole is another popular material used in midsoles, it is a pressurized gas-filled cushioning system that provides excellent shock absorption. The choice of midsole material can also affect the weight of the shoe, which can be important for certain activities such as running or basketball. Additionally, some sneakers feature a dual-density midsole, which provides a different level of cushioning and support in different areas of the foot, catering to the needs of the wearer.
