I ordered my normal size and they definitely run small. The good thing is that they are soft enough that I can put them on. I think they should be a little tighter so they don't slip off. It sucks a little because when I tried to take my shoes off my foot got stuck in it (probably due to holes/gaps in the shoes meant for airflow). I will wear them for everyday use around the home/garden or for quick errands. The soles feel very thin and don't offer enough support. I see that my heels hurt if I wear them too long.
