Although I use these sneakers as my primary walking shoes, I have some issues with them. First, the SIZING is complicated. I bought them in my "normal" size; yet they feel snug and not as comfortable. So, I compensate by wearing them with thin hose. Second, all the ads say that you will notice a difference and achieve a good workout; however, I don't notice ANY changes in my gluts or other muscles. Initially, I felt some discomfort in the gluts (not painful, just uncomfortable), but that's no longer an issue (I guess I became used the walking in these shoes).  Finally, if you are ONLY walking, these would do, but every now and then, I like to break into a sprint since I usually walk with my dog and he likes to jog now and then. Well, I'm afraid to try that in these rockers...I'm afraid I'll lose my balance and fall. I also found the price excessive, but felt I got a better deal through Amazon. Some crazies spend twice as much for these! Next time, I'll just get a good pair of plain ol' all purpose sneakers and save some bucks.
