I wear a size 11 street shoe and purchased a 13.  It was a good fit, but the shoe itself was clunky, especially at the ankles.  I dance in  Black Bloch Boost DRT's and appreciate the sleekness of that shoe.  I thought I would give these a try since I am in search of a nice looking white pair of dance sneakers in addition to my black ones.  I sent these back to Amazon the next day with no problems from Amazon.  On to another pair.
