Crocs Sexi Flip Women's Shoes (W4)(W4)

I've had a black pair of Crocs sandals for about 2 yrs. Loved them from the moment I got them, and decided to get additional colors! Unfortunately, the pink and khaki pairs have not been consistent with one another nor with the black. My black are size 8, it's perfect! Has stretched slightly over 2 yrs but not to any level of discomfort or too worn out, as you can see in the picture. Even when I bought them, they were not too tight or too small. I ordered the khaki pair in 8, way too small and VERY tight around the ankle to the point of discomfort. After reading reviews, and seeing size 8 in pink was unavailable, I figured I'd try the 9 in pink...too big, even wobbly. So I then ordered the 8... Too tight and uncomfortable on my ankle and between my toes. You can almost see how uncomfortable the thing is between my toes in the pink compres to the black. The khaki was worse: even smaller than the pink although also in size 8. You can see how close to the edge/almost over tlmy toes are. Suuuuuper disappointed. I love my black pair and had to throw away my other sandals from maybe a decade ago so was excited to get more Crocs...major disappointment.
