Well, I'm not sure if these are considered booties but I hope they will act like my cold weather ones to update an outfit. I needed a lower heel than those Angie blogged about but didn't want flats either. These were on the Nordsrtom site and arrived yesterday. I wore them last night and think they will be comfortable.

I usually wear a 7.5 or 8 and ordered the 38. They fit like a 7.5 so run about a half size small. They probably will not work for wide feet, but those needing a narrow shoe should be happy with them. They also come in blue and black.
