A sole structure of Goodyear's dual-intake air-capsule shoes includes a sole formed with a vent slot; a heel portion provided with an air-capsule receptacle, in which a T-type intake slot is disposed between the vent slot and the air-capsule receptacle, and two intakes are arranged by side of the T-type air-intake slot; an air capsule provided with a bottom end formed with a fixing hole and an elastic pillar fixed to the fixing hole of the air capsule for supporting the capsule. The level of those intakes is lower than that of a sole's bottom face. There are front sole lines formed on the sole's bottom face and a heel arranged on the sole for direct contact to the ground. A connection part is formed with an intake, while the heel is provided with a channel. Every intake or outlet is provided with a one-way valve such that air is allowed to flow in one direction, that is, to enter the capsule through the intakes and leave the capsule through the outlets.
