I own 4 pairs of Shape-ups and noticed my 24 year old son's posture was going from bad to worse-- he is an actor, so it is very noticeable on stage... so, I purchase a pair of these for him.  He loves them and wears them everywhere!!! His posture has improved enormously and he looks and feels taller-- which he has no objections to LOL... great men's shoes, kudos!
