An adjustable socket system includes a distal end portion having an axis, and a frame having a plurality of elongate fingers longitudinally extending from the distal end portion. Each of the elongate fingers defines at least two segments pivotally connected to one another and extending in a longitudinal direction relative to the distal end portion. The at least two segments are pivotable inwardly or outwardly relative to the axis. At least one elongate element is adjustably connected to the plurality of elongate fingers and forms part of a circumference of the adjustable socket system.
