The envelope encloses a filling material that can change its shape continuously. The front end of the envelope is located at a distance 2/3H ? 5% from the heel, wherein H is the maximum length of a sole lining that may be inserted into the footwear. The envelope is arranged at an angle of 5 to 15 degrees with respect to the longitudinal axis of the sole towards the inner side of the heel. The length of the support envelope is 4/9H ? 10%. The inner periphery of the support envelope is generally straight or slightly convex and crosses the concave inner edge of the stiffening plate at a distance of 2/3H ? 5% from the heel and extends rearwardly towards the heel.
