Uneven ground requires either a component adaptation in the sagittal plane or in frontal plane or both. The lack of adaptability of prosthetic components requires compensational movement strategies by the user. Common energy storing and returning (ESR) feet have some basic flexibility through the carbon structure allowing for some limited adaptation in both planes. For the frontal plane the split toe feature adds some functionality. However, even with split toe the ROM is clearly limited and needs high force impact for minor adaptations. Now there is a novel foot module allowing for 10° inversion/eversion through a dedicated joint.
