Running differs from walking in several ways. While walking, humans push off the side of their feet while keeping the center of gravity over the leg taking the step.A primary component in contemporary design is the addition of proper cushion to the midsole.Cushioning in the shoe functions to protect the runner from objects on the running surface while helping to prevent pronation where the foot rolls to the inside.
