Walking sole

A walking sole adapted to be used under an immobilizing bandage on the lower leg for maintaining all foot joints in a rigid condition, said walking sole having a lower running surface coming into contact with the ground formed of three longitudinally spaced essentially flat parts, and said flat parts joining one another with rounded transitions, a forward one of said parts curved upwardly from a central part at an angle betwen 25.degree. and 35.degree. and a rear heel part sloping upwardly of said central part at an angle between 12.degree. and 25.degree., sole dimensioned to provide a distance between a bottom plane of said central part to a highest point of said forward part of (11.+-.1)% of a length factor and having a distance between said bottom plane of said central part and a highest point of said rear part of (3.+-.1)% of said length factor, said length factor equal to 1.5 times the length of said sole in mm--15 mm, a rear end of said walking sole aligned approximately at a right angle to said central bottom plane, and an uppermost point of said rear end and an uppermost point on a front end of said sole aligned to lie in a plane approximately parallel to said bottom central plane.
