My sandals came with different lengths of straps, so one side I had to tighten more and then the other, and now that strap touches the ground.  Absolutely ridiculous, even though they are marked the same size, one is clearly different and uncomfortable to walk in. Ive wanted these for over a year now, and unfortunately they were a gift so I was unable to return them in the appropriate time window, which was less than 30 days btw, amazon prime or not.
