I was ok was sewing in the straps myself, and the shoes themselves are fine, but the straps came in two different widths, one thick and one thin.  There were two straps, which I assumed were one for each shoe.  I didn't realize until later that they were two different widths.  Maybe I was suppose to use one strap for both shoes and just cut it in half, but I don't think it was long enough to do that.  Other than that issue, I liked the shoes.
