Abstract: A folding step ladder includes a climbing part pivotally connected to a supporting part. Each foot of the ladder has a first part and a second part. The first part has first connecting structures to connect to one of the side members of the step ladder, and second connecting structures to connect to the second part. The second part has connecting structures for connection to the second connecting structures and a standing surface via which the ladder foot rests on the underlying surface. All of the first parts and at least two second parts of the feet are identical; moreover, in relation to the second parts of the ladder feet on the supporting part, the second parts of the ladder feet on the climbing part are fitted on the first parts of the ladder feet such that they have been rotated through 180° in relation to the first parts.
