I have the 890 Komen's same style#890,totally different material across the top doesn't breathe as well and fits snugger across the toes it's just different then I was expecting the bottom of the shoe length is the same when I hold them together its the material that changes the fit. not as happy with these as the 890pink and black komen edition of the shoe. definitely go up a size NB seemed to have changed the fit a bit over the past 3 years or so I don't know maybe a different manufacturer.They seemed to have cheaped out. If your looking for a true running shoe this is not the shoe.
