“sizing info is inaccurate”

“I haven't run in these shoes, I just received them in the mail and have to return them. It warns that they run large and to order a half size smaller, but in my case, that couldn't have been further from the truth. I wear a size 8 normally. I ordered a size 8, and my toes were butting up against the edge of the shoe and wearing them around the house for a few minutes, my circulation was being cut off. Unfortunately, there are none available in a size 9 to try out.”
