I was really excited to get these shoes. I walk often and wanted to see if these really work. After a 3mile walk around my neighborhood I could really feel it in my butt and inner thighs. The only downfall of these shoes is that they aren't really all that comfortable. They made my toes tingle and my shins hurt. They are not really supportive shoes and that in itself is enough to prevent me from wearing them all the time. I now switch back and forth between these shoes and my Nike shoes. They do work different muscles in my legs, but they bother in my feet in the process. I guess it's a trade off!
