I am returning my first pair because one shoe (the left one) was slightly (but noticeable once on) larger than the other. Also, the shoes were a bit larger than what I expected after reading many reviews about sizing.

My first pair did not work out - first because the two shoes had a manufacturing defect in the shoe shape. Also, because so many people suggested sizing up a whole size, I sized up 1/2 size. I should have ordered my normal sandal size, as these were to large in a 9.5. The second pair fit perfectly in size 9, my normal size for sandals. For enclosed shoes sometimes I do size up 1/2 size.
