advanced insoles (?) for running shoes

I haven't heard of those before, but I'm really curious about how well they're working out for your friend. I just bought a different kind of insole last week and am deciding how I feel about it. I've honestly always been more worried that I'll accidentally injure myself while exercising then that I won't be healthy because I don't exercise. That fear has stalled many exercise programs in the past, and I'm trying to get past it this time round.
