These do run large, my 13 month old still has room to spare in the 6-12 m size.  At first I hated them because I saw them leave little marks on her ankles.  So I stretched them overnight by putting them around jars.  After that I was very happy because they do stay on and the soles are way softer than Pedipeds (which don't leave marks but are stiff soled, not good for little feet).  The blue flowers seem to go well with most all of our outfits.  They are wearing well, not scuffing etc., although the soles stiffen when they get wet.  I will continue to buy Robeez Soft Soles.
