I'm in love with these shoes!  In the picture it looks like they're a sort of rainbow, woven fabric, but in person they are shimmery!  It's like they have rainbow lurex in the fabric or something.  Fabulous looking!  They fit a little smaller than my other Rocket Dog sneakers of a similar style, but not enough to make me get a bigger size...I know they'll break in and be fine.  If you don't like your shoes to really fit against your toes like I do, you may want to go up a half size.  I'm so anxious for warmer weather so I can really show these off!
