I have a lower back issue which flares up when I do alot of walking, and bought these on the recommendation of a friend. I balked at the $100 price tag, but as we were headed to the state fair for the day I sucked it up and bought them. I'm so glad I did. I made it through the entire day without any problem and thse are now my favorite shoes for just about everything except going to work (I would wear them there to, but we're not allowed to wear sneakers.) As soon as I put them on I noticed my posture changed, I usually make a conscious effot to walk with good posture and these made me do it without having to think about it. My one complaint is they are not aesthetically pleasing. I bought the black and blue ones which seemed the least oldladyish. (I'm 27, I shouldn't hve to wear granny shoes!) Under jeans they are not as noticably weird looking as they are on the shelf at the store. I really wish sketchers would put out some work appropriate ones. If you have lower back pain, try these. Just put on a pair and walk around the shoe dept of your local store. You won't be able to leave without a pair.
