love the material and the style, but they are a big larger than expected; and i ordered a smaller size (8.5) to get a tighter fit. (i wear 8.5 to a 9, depending on shoe.  i haven't worn an 8 since elementary school.)  need these to stay on during my rafting trips. i'm hoping after i wear them in a couple of weeks in the water, they will shrink when they sun-dry.  otherwise, may return them for a smaller size.
