Abstract

A shoe cushion for safety shoes includes a plurality of combination pieces pivotally connected with each other. Each of the combination pieces has a first side formed with a pivot shaft and a second side formed with a pivot groove. The pivot shaft of a first combination piece is inserted into and pivotally mounted in the pivot groove of an adjacent second combination piece. Thus, the combination pieces can be pivoted relative to each other so that the shape of the shoe cushion is changed freely so as to conform to the profile of the shoe sole of the shoe body and the profile of the user's one foot, thereby providing a comfortable sensation to the user wearing the shoe.
