At my job I walk on concrete floors 8 hours a day and lift and carry items heavy items.  Just two hours into my normal work day and my feet are usually killing me.  I bought these shoes and now the painful feet are gone. It's very lightweight, roomy and comfortable, and I like how the soles don't look too thick and rounded like other "toning" shoes.

I don't feel any difference in the areas where this shoe says it's supposed to tone, but my job is very physical anyway so maybe those areas are already toned to the max?  When you first put them on you do notice a significant difference in the feel of the sole as compared to other shoes and you do have to adjust your posture/walking.

I can't really say much in regards to its toning aspect as I have yet to note any soreness or change in muscle tone, but I highly recommend these as walking shoes, especially if you use and abuse your feet as often as someone like me.
