I ordered two pairs of Crocs, this one and a work clog, in the same size I always buy, 8M. What I received was 8W, which is good, otherwise I probably would have the problems with the little toe rubbing, as in other reviews.  This shoe is also much shorter than the work clog.  I would advise buying a size up in this shoe to be sure your heel or toe aren't hanging off the end.

I'm adding a note to caution that unless your balance is excellent, you shouldn't try this shoe. The heel is higher than it looks in the photo.
