i LIKE THE SHOE BUT FELT THE STRENGTH STYLE WAS LIGHTER IN WEIGHT WHILE STILL BEING STABLE & THE METABOLISM ONE IS LIKE WALKING ON AIR BUT DOESN'T HAVE GOOD SUPPORT. I GUESS IT DEPENDS ON WHICH THING IS MOST IMPORTANT. I WORE MY STABILITY FIRST TIME TODAY (IN THE MALL) & THEY WERE VERY EASY TO WALK IN. COULD LATER FEEL A WORKOUT IN THE LEG CALVES, HOWEVER, ONCE HOME COULDN'T WAIT TO GET THE WEIGHT OFF OF MY FEET. I WAS IN THEM TOTAL OF 5 HRS BUT ALSO DID A LOT OF STOP & GO SHOPPING. MY FINAL ANALYSIS IS THAT THIS IS A GOOD SHOE TO SHAPE UP YOUR LEGS BUT IF YOU ARE BUYING FOR WORK & COMFORT, GET A DIFFERENT STYLE.
