ABSTRACT:
A walking sole to be used under an immobilizing bandage on the lower leg whereby all foot joints are rigid, includes a running surface having three essentially flat parts which are spaced longitudinally and merge into one another with rounded transitions. A forward or toe part is curved upwards from a flat central part at an angle ranging between 25.degree. and 35.degree.. A hindmost or rear heel part slopes upwardly from the central part at an angle ranging between 15.degree. and 25.degree.. The vertical distance between the bottom of the central part and the highest point of the forward part is (11.+-.1)% of a length factor, which factor equals 1.5 times the length of the sole in mm--15 mm. The vertical distance between said bottom and the highest point of the heel part is (3.+-.1)% of said length factor. The rear end of the walking sole is approximately at a right angle relative to the bottom of the central part and the uppermost point of the rear end and of the front end lie in a plane which is approximately parallel to the bottom of the central part.
