* Mesh is a type of breathable fabric made from interlaced fibers to create a material that resembles a net. It is commonly used in athletic sneakers as it provides ventilation to the feet during physical activity.
** EVA material is a foam commonly used in the midsoles of sneakers that provides great shock absorption when walking or running. While "comfort" is (of course) a subjective term, it is often considered more comfortable than traditional midsole and outsole materials such as cork, leather, and rubber.
