Just bought myself a pair of those new "shape-ups" type walking shoe the other day. I first saw them on the Rachael Ray TV Show about 2 years ago. I knew that they were very expensive.
I was at Kohls the other day and saw the Sketcher Shape-ups for $110. Here is a photo of the Sketcher:
This morning was the first day I tried walking in them. At first they feel very strange. It feels like you are teetering on a log. They are a little awkward to walk in at first too. But after awhile, I got the hang of it. I really felt my leg muscles working as I was walking and I think they give you a better cardio workout too because it seems that my heart rate climbed faster walking in these shoes than it does when I walk in regular walking shoes. I think it will take a little while to get used to them, but I'm gonna give 'em a try.
