After 2 years of almost constant daily wear, my old Skechers Shape-Ups were beginning to wear out. These are just as comfortable, and I fully expect to enjoy them as "daily wear" shoes for some time to come. Note: I did not purchase my first pair of Shape-Ups specifically as "exercise shoes" as they had been touted to be. No, I had damaged my ACL and had been in pretty constant pain, using a cane to alleviate some of the weight taken by the damaged knee, etc. The Shape-Ups did two things for me: they let me relinquish the use of the cane by doing a GREAT job of absorbing shock, cushioning my walking, and the slight instability in the heel area worked to augment my rehab exercises designed to strengthen the knee's stability. Over the course of the last couple of years, unless I have engaged in extended (several hours' duration) exercise involving locomotion or a LOT of simply standing, the knee pain has almost entirely disappeared. Was it all the Skechers? Probably not, but the difference in endurance between wearing them and wearing other very good shoes has been like night and day.

The above is strictly one guy's experience, but as one "data point" it holds much more significance for me, of course, than any number of broad surveys. *shrugs* As for me, until I can find shoes that treat my knees (yes, the other knee is getting older, too *heh*) as nicely, these shoes will be my fav.
