I have been wearing this shoe for several years. I have severe Arthritis in my knees and need a good supportive shoe. First...I had to get a MAN's shoe to get the support I needed. I have tried every womans shoe possible. They don't last as long as the Men's... nor do they support as well. So I buy a men's size 7. Don't think its fair that Men's shoes are made better than womans...I have researched this for many years. Even the same exact shoe ..."Sketcher's Energy" ...the men's version will last 3 times longer than the womans. This being said...This shoe has apparently been discontinued in favor of placing that rocker panel on the bottom of it! Can't get the origional version any longer. Please! I know these  "excersise" shoes are a fad, but they are impossible to walk in ...especially if you have knee or other orthopedic problems. Again, its only the very young who will venture to wear these shoes. Is there no justice? Why must middle aged and older people be forced to give up what is so important to them in favor of a new fad? My Foot Doctor said these shoes are a very poor choice for anyone to wear and he forsees many problem resulting from the use of them. Why must Skecher take a shoe that is a very good seller and change it?????I see many people wearing this shoe when I'm out and about. What are we to do now? I will no longer be faithful to the Skecher brand.
