Not sure this is the best product and they make the shoes you wear much ...
I got these after my foot had started to heal.  They did help but the seam on the bottom side caused discomfort.  Not sure this is the best product and they make the shoes you wear much tighter.  recommended by a friend who had good luck with them.  I've had better luck changing to a pair of shoes with better arch support and loosing a few pounds.
