Abstract
A socket for engaging a residual limb includes a plurality of hard counters, each configured to engage the residual limb at defined “go points”. The go points can bear pressure without discomfort or impeding range of motion. The counters are further configured to avoid contact with identified “no go” points where excess tissue may inhibit motion or experience irritation upon movement and which include one or more contoured pads to more effectively engage the bony prominences of the limb without inhibiting motion. A chassis from which each of the counters may flexibly depend connects the residual limb mechanically to a limb extension. A lacing system alternately intersects the counters and terminates in a tensioning reel. Rotation of the tensioning reel in a first direction will draw the laces over each of the counters such that the tensioned laces will draw counters together to engage the residual limb.
