Abstract
A shoe includes a first plate and a second plate that are located in a forefoot portion of the shoe between an upper and an outsole of the shoe, and one or more springs for biasing the first plate and the second plate apart from each other. A device for a shoe includes a first plate and a second plate that are installable in a forefoot portion of the shoe, and an energy return member positioned between the first plate and the second plate. A method of using a shoe includes applying, with a foot, a force on at least one of two plates that is positioned in a forefoot portion of a shoe, so as to move the two plates together and increase a loading of a spring, and launching the foot due to the two plates being moved apart by the spring as the foot is being lifted.
