I have had my share of sneakers and checked out both these and the Shape Ups and I must say, these rock.  Forget the Sketchers Shape-ups, esp. if you have bad knees and/or are out of shape.  Some of my friends who have both ailments were uncomfortable in them and feared falling down.  Of course, weight, age and health had much to do with it.  Personally, aside from looking silly they were comfortable and not hard to walk around in.  However, if needing to sprint off, hopefully you aren't wearing the Sketchers.  Now the Easy tones, you could totally take off in.  One reviewer had said these made her want to walk faster and I agree.  I love these shoes, I have seen changes in tone and I am not in perfect shape (could be classified as overweight/obese).  The black/silver ones look nice with most business type dress wear.  My feet did feel achy and tired after wearing them for 5+ hours (up to 11).  However, the extra exercise is proving beneficial.  My only complaint, we need more colors!  Thanks Reebox!
