I'm a heavy equipment mechanic and a fairly big heavy guy, who's been plagued with foot and ankle problems for years. I have a wide flat foot and I've suffered all kinds of pain and had all sorts of alignment issues. I've spent many hundreds of dollars and tried every orthotic insole known to man, including ones I got from a podiatrist. Some will help for a short time or to a certain extent temporarily and I have seen similar craftsmanship and quality, but I'm here to tell anyone who's on the fence about getting these insoles, just do it! They are worth every penny. And this company has the best customer service I've seen! They will promptly stand by their product and their money back guarantee without an issue, so why wait? And why not try them? You have nothing to lose and everything to gain! I am truly amazed at what these insoles do for my feet, ankles, knees, and back. I would go as far as to call them the "Holy Grail" of orthotic insoles! They cradle your feet with a comfort I have never felt before. I can walk and strut with confidence, energy, and no pain! My sister, who has similar feet and similar pain issues, is and nurse who is on them for many hours without rest... and she has been having great success with these for over eight months... that's testimony enough! From what I've read, it seems that athletes are having a lot of success with them as well. I'm not getting paid to say any of this, I just want people to stop suffering. You don't have to suffer anymore..
