Abstract
Footwear articles for walking are provided. In one example, a footwear article may include a midsole with a lower surface of constant curvature extending from a heel of the midsole to a toe of the midsole, wherein the lower surface maintains the constant curvature throughout a stance phase of a walking gait. In this way, a smooth step-to-step transition and a smaller range of oscillation of the center of mass of the wearer is achieved, and energy expenditure during walking is reduced. In turn, a wearer of the footwear article may smoothly walk for extended periods of time with reduced fatigue.
