I have been wearing these shoes for a month now.  When I first received the shoes I definitely had to get use to wearing them.  After a week when I would wear the shoes it felt like a normal pair of shoes.  I work in retail and they helped my posture and my stride at work.  I don't always move around, but the days I do, I can feel the work out after I take them off.  I would definitely recommend these to anyone, and have.
