Abstract: The invention relates to a resilient foot insert for an artificial foot, having at least one leaf spring. In order to increase structural strength, the at least one leaf spring comprises a plurality of leaf spring elements which are coupled in parallel, are arranged next to one another and are connected to one another at their two end regions. Between these two end regions, there is a clearance distance or gap between an adjacent pair of the leaf spring elements. An adjustable pressure buffer in the gap adjusts the deformation characteristics of the at least one leaf spring.
