A shock absorbing apparatus (200) includes a flexible membrane (204) defining an accumulator cavity, and a compression assembly defining a compression cavity. The compression assembly is disposed within the flexible membrane (204) such that viscous fluid contained within the cavities may be exchanged therebetween by a damping orifice (238), fluid conduit and or valve mechanism. The accumulator cavity deforms in response to the application of a transmitted impact load, and is capable of storing and releasing potential energy in response to the application and cessation of the transmitted impact load.
