Expectations on a scale of 1 through 10 were a 4. Money back guarantee a big plus in my decision to purchase. Did the foot pressure test AFTER standing on my feet all day, 10 hour shift. I am middle aged, overweight 40+ lbs, I wear work boots 5 days a week, my feet hurt by the middle of my shift, everyday. NOT TODAY!!!
I have the 430 insert They felt sturdy, no slipping, comfortable, like a very soft foot massage I kept waiting for my feet to hurt but never happened, not only did my feet feel better by the end of my shift, my ankles were not throbbing, my knees did not ache and my lower back even felt less pressure! Instead of waddling out the door after work I was actually walking the same as when I walked in! A fantastic delight that tickled my spirits. I hope they do the same for you!
If in doubt try it out! Hold on to the receipt and original packaging, just incase you chose to return them and if not pleased don't be afraid to return them that is why the guarantee it there! Also I did the foot test 3 times because first time I didn't have a clue what I was doing, then I actually read how to do it as I was doing it, just wanted to be sure I was purchasing the correct inserts. Your feet will thank you in many ways & you are worth it! =)
