I'm normally a size 7, but I got a 6 because they run big. I got the grassy colored one before of the same brand and after 2 years of squatting, the front started ripping. Bought the same brand with a different color because even though I know it may rip again, these are the best rain boots I have ever had. They are cheap, comfy, and the only brand I can find with beautiful designs, not just one color.
