This shoe is well constructed and has great cushioning (vital to someone who walks with a pounding pace like me).  It does take a little time to get used to the shoes, and at first they feel a little wobbly.  I don't just use them for exercising, I also use them for their excellent support and helpfulness in keeping my body aligned.  At the end of the day, I can't wait to take them off as they are rather heavy.  They are a pricey shoe, but I am glad I bought them.  My next purchase will be the Sketcher Shape-Ups, which are only $110.  Their construction appears to be the same, but I won't know if they perform as well until I get a pair.
