Yeah Superfeet are great! My husband has them in every single pair of shoes he owns (green ones). He immediately takes out the insoles and puts the superfeet in. He even has them in his slippers!
I really haven't needed them until I started riding. I ended up getting the specialized inserts (previous post). Didn't even think about superfeet.
Was at REI yesterday and the superfeet are currently on sale through
May 13th. Give them a shot. There is a little reference book near the display that explains the different colors/uses for each one. -N
