摘要： A shoe includes a first part wore by wearers and a second part which includes a C-shaped resilient plate which is fixed to an underside of the first part by its top. A first pin and a second pin are respectively connected to the front end and the rear end of the resilient plate. A base includes a front end which is pivotably connected to the first pin on the resilient plate and two lugs extend from the top of the rear end of the base. Each lug has an elongate slot and the second pin is movably engaged with the two elongate slots of the two lugs. The resilient plate is moved up and down when the second pin is moved within the elongate slots of the base.
