I have owned several pair of this particular style number, both in white and in black.  First tried them after I had broken my ankle, and had to wear a brace over the ankle that went inside my shoe.  These helped me feel more secure when I started back on my feet after being laid up for over 2 months while the ankle was mending.  I find that it is the most comfortable pair of walker/sneakers I have tried.  I have tried other brands, and they are not nearly as comfortable as these.  I sincerely hope that Propet never quits making these!
