The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.
