An adjustable socket system (100) includes a distal portion (102) and a proximal portion (104). An axis (106) extends between the distal and proximal portions (102, 104). A plurality of struts (108) are connected to the distal portion (102) and distributed circumferentially about the axis (106). The struts (108) at least in part define a receiving volume (114) adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts (108) are moved radially outward relative to the axis (106) to loosen the fit of the adjustable system (100), and a closed configuration in which at least some of the struts (108) are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system (100). A tightening system (1050) is operatively connected to the struts (108) and arranged to tighten and loosen the fit of the adjustable socket system (100) on one or more areas of the residual limb.
