I am almost ALWAYS a 10.5 even with the amazon size fit it said 10.5 would be fine.  But nope.  These sneakers run 1/2 a size small. My toe was rubbing in the tip of the shoe.  I had to return these.  I did not want to exchange them because they didn't even feel that cushioned, i think the first triumphs were softer and cushier than this pair, these felt really stiff.  The quality was just not there for the $87 price tag.
