 The purpose of this study is to investigate the long term balance-enhancing effects of insoles that are hard and thin for older adults. Thirty older female adults between the ages of 65-84 years will be recruited for this study. Twenty participants 20 will wear the experimental insole and ten 10 participants will work their usual insole, during a 12 week period. Balance and foot sensitivity testing will take place at 0, 6 and 12 weeks. These tests will involve measurement of body motion and foot pressure in order to evaluate balance control. Additionally, each participant will be asked to return a bi-weekly postcard that will report on footwear wearing patterns and any falls or fall-related incidents that have occurred during the 12 weeks.
