I ordered a size 8.5 and it fit perfect.  I had another pair of Ryka running shoes and they also were 8.5.  This is the size I usually wear, so I'd say this has good sizing.  They look really cool - the colors are great.  The only down side are the toes are very slightly pointy and looks slightly odd, but not noticeable to anyone else.  I think these are a good price.  I haven't run in them yet, so might have to get back to you on that!
