This boot is super cute, especially cuffed down. But, it really runs small. I wear an 8 1/2 and can go either way on Crocs. Since I know Ocean Minded run a bit on the small side I ordered the 9, but should have gone with the 10. The leather is stretching some, since I wear them quite a bit, so they don't pinch any more.
I definitely recommend ordering a size up for whole sizes and a size and a half for half sizes.
