Our RGM orthotics were made to conform to the shape and contours of your feet. Our orthotics were designed to improve the alignment of the feet and legs, thus relieving any symptoms of abnormal foot function. During the first few weeks, your body will gradually become accustomed to this new and proper alignment. Because each human body is different, the exact period of adjustment is difficult to determine. It may take 2 - 6 weeks. During this adjustment period, you MAY experience mild discomfort in other parts of the body, such as the knees, hips, or back. This discomfort is temporary, and should disappear as the orthotics help the foot to realign and function more efficiently.
