I ordered this in red in a 9.5m.  My normal men's size shoe would be an 8.5m.  My toes touched the end of the shoe.  On the plus side, they were smaller in width too so they were nice and snug in the heel.  I am returning the 9.5s and ordering an 11 in the men's.  I decided to go with the 11 since I am not sure how much of a difference the .5 makes.  The red is a nice and bright (which I wanted).  The laces are not speed laces and there is absolutely no arch support.  But the shoe looks well made and should last well.  I used the super saver shipping and returns so it cost me nothing to exchange.
