Abstract
A sole cushioning module includes a contacting plate, a base plate, a connecting portion and a first spring leaf. The contacting plate abuts against a sole. The base plate and the contacting plate form a space. The connecting portion connects with the contacting plate and the base plate. The first spring leaf is located within the space. The first spring leaf connects with the base plate. The first spring leaf is curved and forms a first outer curved surface. A first region of the first outer curved surface abuts against the contacting plate. When the contacting plate moves towards the base plate, the contacting plate presses on the first outer curved surface. The first spring leaf deforms, and the first outer curved surface slides relative to the contacting plate. The first region shifts towards an end of the first spring leaf connecting with the base plate.
