Abstract
Abstract A shoe or sandal (1) is chosen which fits the patient's foot. One or more blanks (13, 14) of thermosoftening expanded plastics (e.g. an expanded cross-linked polyethylene) for constituting the insole (16) are heated above the softening temperature and inserted in the shoe (1). The shoe (1) is fitted on the patient's foot and the patient is walked until the insole (16) is below the softening temperature. The insole (16) may remain in the shoe (1) or may be transferred to the patient's own footwear.
