I ordered these in my normal size, 7, but my toe was right at the top when I tried on, would definitely need to 1/2 size up.  I would have just exchanged them for a bigger size, but I ordered these in grey, they really look more of a taupe color, not grey at all.  And it's probably just me, but I did not see what was so cute about them once I tried them on.  :(
