I've had body alignment issues since I was a kid (I am 40 now)— regular trips to the chiro and osteopath, which would help for a day or two only. I had constant pain between my shoulder blades, worsening when I stressed out.
I first tried the insoles - I got a bit uncomfortable for about four days as my knee started to swollen. I contacted the Biopods team, asking them if it was normal... and it was! I had a torn meniscus, which got fixed (just random clicks from it, but it was okay) but healed following my lousy alignment. Because of the insoles, my knee got a free rehab (!), and after four days, it got much better, and since then, I can't feel any "clicks" and my knee feels safe (for those who know the feeling when something happened to your limb and you feel you can't rely on it as much as you did before - doesn't feel safe). My family doctor told me it was because I disturbed the misaligned scar tissue that had to reform itself to get the proper alignment—NO MORE BACK PAIN for over a year. I can walk for hours without feeling my legs or feet hurting. No more sprained ankles, either... Since then, I have bought three pairs of shoes, introducing my wife to them and hoping there will be young kids' options soon (Biopods if you read me... :)). This product works, and I highly recommend it.
