this is my first negative review. I was really looking for a more durable comfortable replacement insole for athletic type shoes. Product is as described. Instructions were easy to follow and molding process worked well. However, these are the most uncomfortable insoles i have ever worn. i followed typical break in procedure; wearing a couple hours each day. But had increasing foot, leg, and back pain. I gave up for a few months, but recently remolded the insoles and again followed a very gentle break in regimen. Again, increasing foot, leg, and back pain. Maybe they are too firm for me. I have worn other types of insoles without difficulty.
