Usually Rainbows are a decent product but this pair was made with the strap too tight. I bought another pair at a dept store and tried them on before I paid for them and I have no problem with them. This online pair however was a waste of money since I can't enjoy wearing them and could not try before I buy. looks like there is a quality control issue if you can't buy 2 pairs of the same sandals and have them fit the same. online buyers beware.
