I ordered these from Amazon last summer, to have them on hand for wearing in the fall and winter.  I already had a white pair I love.  I didn't take them out of the box until the deadline for return had past . . . because I was saving them for later.  Big mistake.  The box was marked with the right size, but one shoe was my size and the other was a size smaller!  I tried to return them, and Amazon would not take them back for a full refund even though I had never worn them except to try them on, and the wrong product was shipped to me.  Amazon let me return them for a partial refund, barely worth my trouble.  I was very irritated.  Word to the wise -- try on or try out the products you order right away!
