I have been diagnosed with Parkinson's, and have fallen twice. My physician suggested Cadense Shoes and I purchased a pair about 8 months ago. I have not fallen since, and attribute that to these shoes. My only concern is about the lifetime of these shoes, as they are fairly expensive and I can see that the two hard plastic plates at the front of each shoe are starting to move off center. so I am looking for repair facilities if they are available. Otherwise, i'll simply have to order more shoes. bottom line, I have a lot of confidence in these shoes provided that they have an adequate life.
