Comfortable!  Comforting!
My feet feel better when I wear these, and I feel better all over; less fatigue.  Perfect for flat, open sandals.  I place them, try the shoe, and sometimes move them a couple of times to find just the right spot; then I press them firmly in place.  Slightest change in position does make a difference.  I wear a size 7 (women) and have a high arch.  Have tried other insoles; best so far.
