After reading most of the reviews relative to sizing, it sounded as if the sizing of this dance sneaker was totally off.  However, though worried, I adhered to the sizing info and ordered accordingly.  My street shoe ranges from a 6-1/2 to 7-1/2, generally a 7 - and my foot is fairly narrow.  I ordered a size 8 in this sneaker, received today, and after wearing it for a few hours inside, the size seems correct.  The shoe appears smaller than the 6-1/2 clog I was wearing, but feels fine on my feet.  Incidentally, I also have on socks.  Would have given 5 stars if I'd actually danced in the shoes (I do line dancing), but feel it will be fine.
