My daughter is a true size 10 (toddler), the size I ordered, and the Salt Water Sandal was at least 1.5 sizes too narrow; we promptly returned it.  The sandal strap is fastened to the sole in such a way that makes the foot space very narrow.  I would only recommend this sandal for a toddler with small or narrow feet.  I thought I'd save a few bucks and purchase Hoy sandals instead of Stride Rite...well, my daughter now has a pair of Stride Rite sandals that feet her feet perfectly.
