I must first of all mention that I use Dr. Scholl's Double-Air Pillo insoles together with all my "Go" shoes since my feet are a bit skinny and I could use the extra cushion due the rehab I'm doing for my left knee. The ensemble makes me feel like I'm walking on clouds. I've been on "Go" since last summer and it has made such a difference as part of my knee improvement effort (special shoes, special Vasili insoles, physical therapy, strengthening, gym regularly, used to put on knee brace but no longer need to). Loving the variety in styles and design too!
