Shoes Mbt Review

Does Reebok Easytone, Skechers Shapeups and/or MBT work?
Hello!
I’ve been frequently seeing ads for these shoes that supposedly affect your body like exercise would and also help with posture. I was wondering if any of the shoes are effective with that. Any reviews on them would be really appreciated. Also advice relating to these kinds of shoes would really be appreciated too.
I have found that wearing Earth Footwear has helped to tone my legs and improve my posture. They are different from regular shoes because the toes are higher than the heel (sounds kinda weird right?). But its just like walking on an inclined treadmill. Super comfy too!
