I still do, but not as often. One of the problems with falling when you're a polio survivor is that you don't have time to react and protect yourself because of delayed reaction time. So anything we can do to forestall these events helps prevent injury. We all know we have to wear supportive shoes, but there is support and then there is support. Look at your shoes.
Athletic shoes are relatively inexpensive and have excellent support.
Be sure there is a good arch support system inside. You may have a problem here. Feet affected by polio tend to curl inward placing much of the weight on the outside edge of the foot. Not only don't I roll over on my ankles as much, but much of my leg and foot pain is reduced. So much for buying shoes.
