A prosthetic insert unit for cushioning shocks in prosthetics is provided. The unit includes attachment member (150 etc.), a lower sleeve (124' etc), a slide bearing (152' etc.) to allow free reciprocal motion therebetween, an elastomeric energy storage member (124' etc.) received in the interior of the sleeve (124' etc.), a piston (134' etc.) cooperative with said elastomer member to compress same, and an anti-rotation mechanism. Preferably, the anti-rotation mechanism is integral with the slide bearing (152' etc.). The elastomer member provides controlled deflection as well as damping for the insert. Preferably, an anti-click element (269 etc.) is provide to minimize rebound clicking. Acoustical elements (268 etc.) may also be included to minimize noise transmission into other areas of the insert.
