1st pair ordered: 8B...way too short. 2nd pair ordered: 8.5B...again way too short.  I wear an 8AA and thought these U.S. Polo Assn. fashion sneakers would work fine to wear on a very long flight.  They are not true to size.  Also, the foot padding is too small for the inside of the shoe...felt like my feet were on a cushy shelf, toes overhanging.  The other thing, the sneakers had a very strong chemical odor.  I was disappointed.
