I went to Kmart and bought Therashoes. They are 34.99. I think the address is http://www.therashoes.com I bought them last week and wore them for my 7 mile walk and o my were my legs SORE the next day. Right now they are buy one get one half off. They are VERY comfortable the most comfortable shoe I have EVER worn BUT you WILL have muscle soreness if you don't allow yourself time to adjust. Therashoes also have a knockoff of the Fitflops at the Big K and they are currently 9.99 and they are also buy one get one half off. Make sure you try them on as they the sneakers tend to run small.
