I love these sneakers!  I have had them since October and I wear them almost every day.  In fact, my legs, back and feet remind me when I'm not wearing them!

At first I was skeptical--they look a little silly.  I am 30 years old and spend a lot of time walking around at my job.  I was having problems with cramping in my calves and knee/hip pains.  I can't say if I've seen a difference in the appearance of my legs, but I no longer have calf pain or hip/knee pain.  And the comfort continues long after I've taken them off!  I used to wake up in the morning with sore feet and stiff legs and lower back. Sometimes I would even go to bed with sciatic pain.  Since wearing these shoes I have not had any issues with my legs and back.  I also have found that my posture improves when wearing these sneakers.  I have heard others say that their legs are tired when wearing these sneakers.  I haven't felt that way, but I also work out 6 days a week.  If you spend a lot of time on your feet or walking, I highly recommend these sneakers. They are worth every penny. I can't wait to purchase them in different colors and styles.
