I don't have it and I've never tried it on, but I have seen it irl and I thought it was cute. If I remember correctly, the red was sort of muted, but I'm not sure my memory is definitely accurate b/c I went to like 4 shoe stores and all of them had that shoe in assorted colors and I just remember being like "why is it everywhere??"
Zappos usually has reviews though, maybe some of those would be more helpful?
