Normally size up a full size from a street shoe to my running shoes.  These were a still too short.  Received the new pair within about 2 days!  They are very light weight. Medium width is fine. Does not appear to be a lot of cushion for pavement. I have not run in them extensively yet as I still cannot give up my old running sneakers! Would like some more shock absorbers. Ordered orange and the appearance is great! Price on Amazon could not be beat along with the delivery and FAST return.
