These same shoes I bought in Phoenix at Nordstrom's Last Chance.  They were so comfortable that I went ahead and "bit the bullet" and bought two pair (one never knows when the company will quit producing these) at the going price when the pair I had began to wear out.  They are billed as giving one's legs a workout while one walks.  I'm not sure about that, but they are very comfortable and fit my feet snugly (not easy in a sandal).
