I was hesitant to spend this kind of money on walking shoes but I've always been a fitness buff and wanted to give them a try.  I tried a pair on in the store and immediately was impressed with how they worked.  They do look a bit strange on but I get lots of questions when people see me wearing it.  I can definitely feel the difference when walking in them and I can't wait to explore a city by foot one day to really get the advantages of the shoe.
