I have aqua and they are so cute! They fit well, I would say they are a bit big. I usually wear between 8.5 and 9 and am a size 9. There's a bit more room in the sock so I could probably go for an 8.5 (if half sizes are available...can't remember if they were when I was she bought). I also have wide feet and they still fit me well and I don't look like I wear shoes on my wide feet. Haven't worn them yet except for walking around the house but they seem to be quite durable!
