Order this shoe a whole size bigger.  I love this shoes performance.  It does make you feet look small.  SO take heed to the first sentence.  Nike is usually a size smaller than addidas I wear a 9.5 in mens but in nike I wear a 10 to 10.5.  But in this shoe I would go with 10.5 to maybe an eleven if I need to.  Very comfortable and i mean very comfortable and light weight.
