Dr. Scholl's is soft, worthless crap. I have Superfeet green in my hiking boots. In my opinion, if you don't have a foot problem, and wonder if insoles will "improve" anything - no. I wear the best quality socks (Swiftwick), and use the insoles that come with my cycling shoes (Shimano). Most insoles will only absorb energy and take up room. If the volume of your shoes is too big, insoles may help. Good luck.
