A device is provided to support and position a limb extremity in a desired steady position to enable acquisition of morphological data from the underside and the upper portion of the limb extremity in a substantially non-weight-bearing attitude. The device comprises a stretchable envelope, made of a thin elastomeric membrane, and a support provided with adjustable positioning members such as hooks, pegs or clips comprising a proximal end and a distal end. The envelope is provided with laterally extending positioning member engaging portions disposed on opposite sides along the longitudinal axis of said envelope. Said positioning member engaging portions receive the distal end of said adjustable positioning members and thereby enable adjustable support and positioning of the envelope and, in turn, of the limb extremity inserted therein. There is further disclosed a measurement method comprising the steps of inserting a limb extremity into a closely fitted thin stretchable envelope provided with positioning member engaging portions, attaching adjustable positioning members to said portions, adjusting the position of said adjustable positioning members and performing optical acquisition of morphological data of the limb extremity.
