I bought them half a size up, based on the general guidelines for New Balances. This was correct. The shoes failed to hold securely to my heels, however.<br /><br />The construction of the shoe was very thin, to the point of feeling chinsy (though not shoddy). The laces were completely flat and difficult to untie, and the mesh on the toe extended far enough (as is common with runners) that it seemed a likely candidate for tearing due to the big toe.<br /><br />It's probably a decent shoe, but it wasn't right for me. Returning.
