A shoe comprising: an upper and a midsole made of a cushioning material attached to an outsole; the midsole having a radius of curvature at any point of a line from a heel to a toe and interfacing with outsole, wherein the midsole is divided into several zones, the zones comprising: a center of mass zone, wherein the lowest point of midsole and outsole, corresponds to the center of mass of the shoe, such that, when placed on a substantially horizontal reference plane, the center of mass zone defines a transition of a roll of a foot having the highest radius of curvature of the midsole and the outsole, and in that the center of mass is behind a point of the metatarsals, wherein the radius of curvature of the center of mass zone is between 350 mm and 3000 mm; a transition zone towards the heel having a radius smaller than the radius of the center of mass zone; an impact zone at the heel having a radius smaller than the radius of the transition zone; an unrolling zone positioned towards the toe in a location under the metatarsals of a foot and having a radius smaller than the radius of the center of mass zone; and a final unrolling zone at the toe having a radius greater than the radius of the unrolling zone. an upper and a midsole made of a cushioning material attached to an outsole; the midsole having a radius of curvature at any point of a line from a heel to a toe and interfacing with outsole, wherein the midsole is divided into several zones, the zones comprising: a center of mass zone, wherein the lowest point of midsole and outsole, corresponds to the center of mass of the shoe, such that, when placed on a substantially horizontal reference plane, the center of mass zone defines a transition of a roll of a foot having the highest radius of curvature of the midsole and the outsole, and in that the center of mass is behind a point of the metatarsals, wherein the radius of curvature of the center of mass zone is between 350 mm and 3000 mm; a transition zone towards the heel having a radius smaller than the radius of the center of mass zone; an impact zone at the heel having a radius smaller than the radius of the transition zone; an unrolling zone positioned towards the toe in a location under the metatarsals of a foot and having a radius smaller than the radius of the center of mass zone; and a final unrolling zone at the toe having a radius greater than the radius of the unrolling zone. a center of mass zone, wherein the lowest point of midsole and outsole, corresponds to the center of mass of the shoe, such that, when placed on a substantially horizontal reference plane, the center of mass zone defines a transition of a roll of a foot having the highest radius of curvature of the midsole and the outsole, and in that the center of mass is behind a point of the metatarsals, wherein the radius of curvature of the center of mass zone is between 350 mm and 3000 mm; a transition zone towards the heel having a radius smaller than the radius of the center of mass zone; an impact zone at the heel having a radius smaller than the radius of the transition zone; an unrolling zone positioned towards the toe in a location under the metatarsals of a foot and having a radius smaller than the radius of the center of mass zone; and a final unrolling zone at the toe having a radius greater than the radius of the unrolling zone.
