These loafers are decent. As far as the shape-ups are concerned, I want to say the loafers are a more subtle version of the product, the formation of the shoe isn't as defined as other Shape-Up shoes. I also do not notice any real difference in wearing these shoes from other shoes, once they are "broken in". The first two weeks were a bit awkward, but perhaps my body simply got used to the way the weight is distributed differently. Weight distribution is more focused on the arch of your feet than the balls/heels, which can be uncomfortable at first. I have had them for about 1 month and already see significant wear on the outside of the shoe in places you would not expect. All in all, I say this is an average pair of shoes that has the benefit of slightly changing your walking stance and perhaps standing posture, but not to a degree where you notice any focus on the calf or ankles past a couple weeks of wear. Probably overpriced, would be a better buy in the $60-$70 range.
