Goals and Objectives After completing this CME, should have: Assessment and 1) Knowledge of foot- wear construction and Management materials. 2) Skills to accurately assess the fit and suitabili- ty of footwear. Understanding construction and materials aids in properly 3) Current knowledge fitting patients. of the footwear options available to better treat patients.

Welcome to Podiatry Management’s CME Instructional program. Our journal has been approved as a sponsor of Contin- uing Medical Education by the Council on Podiatric Medical Education. You may enroll: 1) on a per issue basis (at $20.00 per topic) or 2) per year, for the special introductory rate of $139 (you save $61). You may submit the answer sheet, along with the other information requested, via mail, fax, or phone. In the near future, you may be able to submit via the Internet. If you correctly answer seventy (70%) of the questions correctly, you will receive a certificate attesting to your earned cred- its. You will also receive a record of any incorrectly answered questions. If you score less than 70%, you can retake the test at no additional cost. A list of states currently honoring CPME approved credits is listed on pg. 176. Other than those entities cur- rently accepting CPME-approved credit, Podiatry Management cannot guarantee that these CME credits will be acceptable by any state licensing agency, hospital, managed care organization or other entity. PM will, however, use its best efforts to ensure the widest acceptance of this program possible. This instructional CME program is designed to supplement, NOT replace, existing CME seminars. The goal of this program is to advance the knowledge of practicing podiatrists. We will endeavor to publish high quality manuscripts by noted authors and researchers. If you have any questions or comments about this program, you can write or call us at: Podiatry Management, P.O. Box 490, East Islip, NY 11730, (631) 563-1604 or e-mail us at [email protected].

fore, mules, , sandals, and court shoes may be seen as being unsuitable. The suitability of each of the main styles depends on the exact styling, heel height, materials used, and perhaps most importantly, the use to which a patient will put the footwear. For example, high heel court shoes may be worn with minimum risks to foot health in healthy individuals, who wear them for a very short time with minimal weight bearing.

A = both feet the same overall length; B = long heel-to-ball joint counter should not dig into the measurement; C = short heel-to-ball joint measurement Achilles tendon or malleoli. Heel fit also influences the entire fit of the shoe because the foot has a different stance inside a high- heeled and a low-heeled shoe, and also functions differently inside the shoe. When walking barefoot, the heel of the foot is lifted about two inches with each step, with the ball of the foot working as a fulcrum for the step-off. The amount of heel rise is proportional to the length of the step. Therefore, the longer the stride, the higher the heel rise. In a shoe with a two-inch heel, there is no rise in the heel, be- cause the shoe is already ac- counting for that rise.
