I have these in the black/purple velvet color.  I didn't know if I would like these style-wise since it was that velvet-type material.  I thought that it would rub off eventually, but it has yet to do that even though I wear these a lot.

I wear these all the time; at work, working out, walking around, and I always feel them working.  I feel it mostly in the back of my thighs.  I'm not sure if there's a visible difference, but my thighs do feel stronger.

These shoes are really comfortable for anything.  I have stood 8 hours straight in these, and I run in these even though they're only made for walking.  The soles haven't worn down a bit either which was one of my concerns.  I'm a little taller too!  I need all the height I can get, and yet I don't look weird wearing them unlike some of the other toning shoes available.

I really like the style of these black ones, they go with anything, and they actually keep my feet really warm in the winter.  I didn't expect to use my sneakers as winter shoes.

They are a really great accessory to any work out routine.  They aren't going to automatically make you toned, though.  These are shoes you should use as a part of your workout and diet regimen.
