     DETAILED DESCRIPTION OF THE INVENTION 
     The following description is provided, so as to enable any person skilled in the art to make use of said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, are adapted to remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide a set of podiatric articles placeable into a shoe and methods of using and delivering the same. 
     A pain scale measures a patient&#39;s pain intensity or other features. Pain scales are based on self-report, observational (behavioral), or physiological data. Self-report is considered primary and should be obtained if possible. Pain scales are available for neonates, infants, children, adolescents, adults, seniors, and persons whose communication is impaired. In accordance with Wong Baker Pain Scale, feeling of the person is characterized by a symbolic face. Specifically, face 0 is very happy because he is not in pain. Face 1 hurts just a little bit. Face 2 hurts a little more. Face 3 hurts even more. Face 4 hurts a lot. Face 5 hurts as much as you can imagine, although you do not have to be crying to feel this bad. The person is asked to choose the face that best describes how he is feeling. 
     A heel spur is an osteophytic proliferation just anterior to the calcaneal tuberosity that extends plantarly along its entire width. The boney prominence develops and points distally at the attachment of the plantar aponeurosis. The condition may be asymptomatic or may result in painful ambulation. 
     The patient usually presents with a complaint of pain located mainly under the medial plantar aspect of the heel. The onset is ordinarily gradual, the pain being most intense in the morning upon taking the first steps of the day, decreasing slightly after a period of ambulation, and then becoming more pronounced at day&#39;s end. 
     In addition, the patient may relate a history of increased pain upon ambulation after periods of non-weightbearing. The condition is rarely totally disabling, although a limp may be present. There is normally no history of preceding illness or trauma to the area, and the condition may be present from a few days to a few months before a patient seeks treatment. 
     It is evident that the major factor in the cause of heel spurs is undoubtedly mechanical, rather than infectious. A heel spur is generally thought to develop from traction on the periosteum that causes consequent subperiosteal ossification. By controlling pronation and lessening the bowstring effect of the plantar aponeurosis, the reactive force will be removed, and the inflammation should subside. 
     It should be noted that there are heel spurs caused by various infectious and arthritic conditions as well. Some of these conditions are rheumatic and psoriatic arthritis, ankylosing spondylitis, Reiter&#39;s syndrome, and Strumpell-Marie disease. However, these cases have been found to be the exception, rather than the rule, as far as etiology is concerned. 
     There are three types of heel spurs:
         I. Those that are large in size but asymptomatic because the angle of growth is such that the spur does not become a weightbearing point, and/or the inflammatory changes have been arrested. This type is usually found incidentally when the foot is X-rayed for some other purpose.   II. Those that are large in size and painful upon weightbearing, because the pitch of the calcaneus has been altered by a depression of the longitudinal arch, and as a result, the spur becomes a weightbearing point, sometimes causing intractable pain.   III. Those that exhibit only a rudimentary proliferation and whose outline is irregular and jagged. These usually are accompanied by an area of decreased density around the origin of the plantar fascia, indicating a subacute inflammatory process. All calcaneal spurs undoubtedly begin in this manner, but only a few become symptomatic at this stage, because in only these few are the etiologic factors acute.       

     The primary symptom is severe pain in the entire plantar surface of the heel with poststatic dyskinesia. Pinpoint palpation usually elicits maximum pain in the area of the medial tubercle of the calcaneus. 
     When taking X-rays, one should always take bilateral weightbearing lateral views. In evaluating the X-rays, one must also take into consideration the pathological processes of early fibrosis, osteophytic deposits, and eventual calcification. From our study and those of others, it is evident that a spur need not be evident on X-ray for the heel-spur syndrome to exist. 
     In the purpose of the current invention, a value M refers both to a dimension of heel projection  110   a / 110   b / 110   c  of the molding model and depth of heel  210   a / 210   b / 210   c.
