My specs-  I run a child care business from my home, so I am on my feet all day long!  I have two kids and two brothers to take care of, again on my feet all day long.  My husband is deployed, double duty= on my feet all day long!
Appeal-  As I don't have much time for anything than what's already on my plate I thought these would be great and hoped I would be sore by the end of the day and feel the daily work out from them (no I didn't read the instructions saying to wear them only 2-3 hours a day, are you kidding me?!  I just got new shoes that suggested weight loss...I wore them out of the store. lol)
Situation-  Prior to getting these shoes I had not been able to exercise, I would drop into bed with my feet in pain!  I would wake up to even more pain in the morning.  I honestly didn't care about the posture stuff or anything else.
Result-  As for toning and firming/weight loss, I haven't really noticed a difference.  My calves are more defined than they have been in a while but no weight loss.  ( I have not changed my eating habits either)  HOWEVER!  This is my favorite part; I no longer have foot pain.  I wake up not dreading to stand up!  I love it!  I also very much appreciate the posture aspect as well.  I feel more confident when I stand.  I did not expect that result...

I have had these shoes for three months now.  I run in them, I wear them from morning till night, if they could make some sort of slipper I would wear them to bed as well.  LOVE LOVE LOVE!
p.s.  I have no idea which kind I bought and I don't know the difference to all the different styles other than the appearance.  If there is a difference I would love to find out.
