I own several pairs of Sketchers that are very comfortable.  These Sketchers fit smaller and are less comfortable than all my other Sketchers due to the memory foam taking up space in the footbed.  This addition should have been compensated for in the size and comfort of the shoe.  The outside fabric doesn't come up as high because of the memory foam.  Because of this, the backside of the heel is lower and therefore causes slippage and rubs.. These shoes should have better arch support along with some adjustments for the memory foam which is a good addition.
