This is my second pair of Shape Ups. I bought my first pair in an outlet store when they first came out but they were a little tight. I bought the largest size they had in stock which was my regular size. I thought they would stretch but they didn't and my toe always bumped the toe of the shoe. The only way I could wear them was bare-footed and that was gross for me.  So, this time I ordered a whole size larger than my regular size and they fit perfectly even with a thick sock. I love the extra workout you get just from walking around.  They are great for wearing all the time but I especially like them on the treadmill.  They are pretty much my "go to" shoe unless I'm wearing sandals or the dreaded work/dress shoe.
