I ordered these in navy/yellow.  They are super cute and wonderfully Sketcher-comfortable.  I can't speak much for their toning effect though I have had some slight soreness in my hams and glutes on days after significant walking in the shoes.

These are great, airy, warm weather shoes.  I have received several compliments on them and I rarely have people notice my shoes.

There is one downside - I wear them without socks.  While they're perfectly comfortable without socks, they've begun to stink a bit.  I don't think that's the shoes' fault though, just my smelly feet.

I actually came back to Amazon to buy another pair in a different color and noticed there weren't any reviews, so I thought I'd put in my two cents of two thumbs up!
